Presenting Your Research

 

Research is complete only when the results are shared with the scientific community.

 

 

-American Psychological Association

 

Imagine that you have identified an interesting research question, reviewed the relevant literature, designed and conducted an empirical study, analyzed the data, and drawn your conclusions. There is still one more step in the process of conducting scientific research. It is time to add your research to the literature so that others can learn from it and build on it. Remember that science is a social process—a large-scale collaboration among many researchers distributed across space and time. For this reason, it could be argued that unless you make your research public in some form, you are not really engaged in science at all.

 

In this chapter, we look at how to present your research effectively. We begin with a discussion of American Psychological Association (APA) style—the primary approach to writing taken by researchers in psychology and related fields. Then we consider how to write an APA-style empirical research report. Finally, we look at some of the many other ways in which researchers present their work, including review and theoretical articles, theses and other student papers, and talks and posters at professional meetings.

11.1 American Psychological Association (APA) Style

 

 

 

1. Define APA style and list several of its most important characteristics.

 

2. Identify three levels of APA style and give examples of each.

 

3. Identify multiple sources of information about APA style.

What Is APA Style?

 

APA style is a set of guidelines for writing in psychology and related fields. These guidelines are set down in the Publication Manual of the American Psychological Association (APA,

2006). [1] The Publication Manual originated in 1929 as a short journal article that provided basic

standards for preparing manuscripts to be submitted for publication (Bentley et al., 1929). [2] It was later expanded and published as a book by the association and is now in its sixth edition. The primary purpose of APA style is to facilitate scientific communication by promoting clarity of expression and by standardizing the organization and content of research articles and book chapters. It is easier to write about research when you know what information to present, the order in which to present it, and even the style in which to present it. Likewise, it is easier to read about research when it is presented in familiar and expected ways.

 

APA style is best thought of as a “genre” of writing that is appropriate for presenting the results of psychological research—especially in academic and professional contexts. It is not synonymous with “good writing” in general. You would not write a literary analysis for an English class, even if it were based on psychoanalytic concepts, in APA style. You would write it in Modern Language Association (MLA) style instead. And you would not write a newspaper article, even if it were about a new breakthrough in behavioral neuroscience, in APA style. You would write it in Associated Press (AP) style instead. At the same time, you would not write an empirical research report in MLA style, in AP style, or in the style of a romance novel, an e-mail to a friend, or a shopping list. You would write it in APA style. Part of being a good writer in general is adopting a style that is appropriate to the writing task at hand, and for writing about psychological research, this is APA style.

 

The Levels of APA Style

 

Because APA style consists of a large number and variety of guidelines—the Publication Manual is nearly 300 pages long—it can be useful to think about it in terms of three basic levels. The first is the

overall organization of an article (which is covered in Chapter 2 “Getting Started in Research” of the Publication Manual). Empirical research reports, in particular, have several distinct sections that always appear in the same order:

 

1. Title page. Presents the article title and author names and affiliations.

 

2. Abstract. Summarizes the research.

 

3. Introduction. Describes previous research and the rationale for the current study.

 

4. Method. Describes how the study was conducted.

 

5. Results. Describes the results of the study.

 

6. Discussion. Summarizes the study and discusses its implications.

 

7. References. Lists the references cited throughout the article.

 

 

The second level of APA style can be referred to as high-level style (covered in Chapter 3 “Research Ethics” of the Publication Manual), which includes guidelines for the clear expression of ideas. There are two important themes here. One is that APA-style writing is formal rather than informal. It adopts a tone that is appropriate for communicating with professional colleagues—other researchers and practitioners— who share an interest in the topic. Beyond this shared interest, however, these colleagues are not necessarily similar to the writer or to each other. A graduate student in California might be writing an article that will be read by a young psychotherapist in New York City and a respected professor of psychology in Tokyo. Thus formal writing avoids slang, contractions, pop culture references, humor, and other elements that would be acceptable in talking with a friend or in writing informally.

 

The second theme of high-level APA style is that it is straightforward. This means that it communicates ideas as simply and clearly as possible, putting the focus on the ideas themselves and not on how they are communicated. Thus APA-style writing minimizes literary devices such as metaphor, imagery, irony, suspense, and so on. Again, humor is kept to a minimum. Sentences are short and direct. Technical terms must be used, but they are used to improve communication, not simply to make the writing sound more

 

 

“scientific.” For example, if participants immersed their hands in a bucket of ice water, it is better just to write this than to write that they “were subjected to a pain-inducement apparatus.” At the same time, however, there is no better way to communicate that a between-subjects design was used than to use the term “between-subjects design.”

 

APA Style and the Values of Psychology

 

Robert Madigan and his colleagues have argued that APA style has a purpose that often goes unrecognized (Madigan, Johnson, & Linton, 1995).[3] Specifically, it promotes psychologists’ scientific values and assumptions. From this perspective, many features of APA style that at first seem arbitrary actually make good sense. Following are several features of APA-style writing and the scientific values or assumptions

they reflect.

 

 

APA style feature Scientific value or assumption
 

There are very few direct quotations of other researchers.

The phenomena and theories of psychology are objective and do not depend on the specific words a particular researcher used to describe them.
 

Criticisms are directed at other researchers’ work but not at them personally.

The focus of scientific research is on drawing general conclusions about the world, not on the personalities of particular researchers.
There are many references and reference citations. Scientific research is a large-scale collaboration among many researchers.
 

Empirical research reports are organized with specific sections in a fixed order.

There is an ideal approach to conducting empirical research in psychology (even if this ideal is not always achieved in actual research).
Researchers tend to “hedge” their conclusions, e.g., “The

results suggest that…”

 

Scientific knowledge is tentative and always subject to revision based on new empirical results.

 

 

 

Another important element of high-level APA style is the avoidance of language that is biased against particular groups. This is not only to avoid offending people—why would you want to offend people who are interested in your work?—but also for the sake of scientific objectivity and accuracy. For example, the term sexual orientation should be used instead of sexual preference because people do not generally experience their orientation as a “preference,” nor is it as easily changeable as this term suggests (Committee on Lesbian and Gay Concerns, APA, 1991). [4]

 

 

The general principles for avoiding biased language are fairly simple. First, be sensitive to labels by avoiding terms that are offensive or have negative connotations. This includes terms that identify people with a disorder or other problem they happen to have. For example, patients with schizophrenia is better than schizophrenics. Second, use more specific terms rather than more general ones. For

example, Mexican Americans is better than Hispanics if everyone in the group is, in fact, Mexican American. Third, avoid objectifying research participants. Instead, acknowledge their active contribution to the research. For example, “The students completed the questionnaire” is better than “The subjects were administered the questionnaire.” Note that this principle also makes for clearer, more engaging writing. Table 11.1 “Examples of Avoiding Biased Language” shows several more examples that follow these general principles.

 

Table 11.1 Examples of Avoiding Biased Language

 

Instead of… Use…
man, men men and women, people
firemen firefighters
homosexuals, gays, bisexuals lesbians, gay men, bisexual men, bisexual women
minority specific group label (e.g., African American)
neurotics people scoring high in neuroticism
special children children with learning disabilities

 

 

The previous edition of the Publication Manual strongly discouraged the use of the term subjects (except for nonhumans) and strongly encouraged the use of participants instead. The current edition, however, acknowledges that subjects can still be appropriate in referring to human participants in areas in which it has traditionally been used (e.g., basic memory research). But it also encourages the use of more specific terms when possible: college students, children, respondents, and so on.

 

The third level of APA style can be referred to as low-level style (which is covered in Chapter 4 “Theory in Psychology” through Chapter 7 “Nonexperimental Research” of the Publication Manual.) Low-level style includes all the specific guidelines pertaining to spelling, grammar, references and reference citations, numbers and statistics, figures and tables, and so on. There are so many low-level guidelines

 

 

that even experienced professionals need to consult the Publication Manual from time to time. Table 11.2 “Top 10 APA Style Errors” contains some of the most common types of APA style errors based on an analysis of manuscripts submitted to one professional journal over a 6-year period (Onwuegbuzie, Combs, Slate, & Frels, 2010). [5] These errors were committed by professional researchers but are probably similar to those that students commit the most too. See also Note 11.8 “Online APA Style Resources” in this section and, of course, the Publication Manual itself.

 

Table 11.2 Top 10 APA Style Errors

 

Error type Example
1. Use of numbers Failing to use numerals for 10 and above
 

2. Hyphenation

Failing to hyphenate compound adjectives that precede a noun (e.g., “role playing technique” should be “role-playing technique”)
3. Use of et al. Failing to use it after a reference is cited for the first time
4. Headings Not capitalizing headings correctly
5. Use of since Using since to mean because
 

6. Tables and figures

Not formatting them in APA style; repeating information that is already given in the text
7. Use of commas Failing to use a comma before and or or in a series of three or more elements
8. Use of abbreviations  

Failing to spell out a term completely before introducing an abbreviation for it

9. Spacing Not consistently double-spacing between lines
10. Use of &in references  

Using & in the text or and in parentheses

 

 

Online APA Style Resources

 

The best source of information on APA style is the Publication Manual itself. However, there are also many good websites on APA style, which do an excellent job of presenting the basics for beginning researchers. Here are a few of them.

APA-Style References and Citations

 

Because science is a large-scale collaboration among researchers, references to the work of other researchers are extremely important. Their importance is reflected in the extensive and detailed set of rules for formatting and using them.

References

 

At the end of an APA-style article or book chapter is a list that contains references to all the works cited in the text (and only the works cited in the text). The reference list begins on its own page, with the heading “References,” centered in upper and lower case. The references themselves are then listed alphabetically according to the last names of the first named author for each citation. (As in the rest of an APA-style manuscript, everything is double-spaced.) Many different kinds of works might be cited in APA-style articles and book chapters, including magazine articles, websites, government documents, and even television shows. Of course, you should consult the Publication Manual or Online APA Style Resources for details on how to format them. Here we will focus on formatting references for the three most common kinds of works cited in APA style: journal articles, books, and book chapters.

Journal Articles

 

For journal articles, the generic format for a reference is as follows:

 

 

 

Author, A. A., Author, B. B., & Author, C. C. (year). Title of article. Title of Journal, xx, pp–pp. doi:xx.xxxxxxxxxx

 

 

Here is a concrete example:

 

 

Adair, J. G., & Vohra, N. (2003). The explosion of knowledge, references, and citations: Psychology’s unique response to a crisis. American Psychologist, 58, 15–23. doi: 10.1037/0003-066X.58.1.15

 

 

There are several things to notice here. The reference includes a hanging indent. That is, the first line of the reference is not indented but all subsequent lines are. The authors’ names appear in the same order as on the article, which reflects the authors’ relative contributions to the research. Only the authors’ last names and initials appear, and the names are separated by commas with an ampersand (&) between the last two. This is true even when there are only two authors. Only the first word of the article title is capitalized. The only exceptions are for words that are proper nouns or adjectives (e.g., “Freudian”) or if there is a subtitle, in which case the first word of the subtitle is also capitalized. In the journal title, however, all the important words are capitalized. The journal title and volume number are italicized. At the very end of the reference is the digital object identifier (DOI), which provides a permanent link to the location of the article on the Internet. Include this if it is available. It can generally be found in the record for the item on an electronic database (e.g., PsycINFO) and is usually displayed on the first page of the published article.

Books

 

For a book, the generic format and a concrete example are as follows:

 

 

 

Author, A. A. (year). Title of book. Location: Publisher.

 

 

Milgram, S. (1974). Obedience to authority: An experimental view. New York, NY: Harper & Row.

 

 

Book Chapters

 

For a chapter in an edited book, the generic format and a concrete example are as follows:

Author, A. A., Author, B. B., & Author, C. C. (year). Title of chapter. In A. A. Editor, B. B. Editor, & C. C. Editor (Eds.), Title of book (pp. xxx–xxx). Location: Publisher.

 

Lilienfeld, S. O., & Lynn, S. J. (2003). Dissociative identity disorder: Multiple personalities, multiple controversies. In S. O. Lilienfeld, S. J. Lynn, & J. M. Lohr (Eds.), Science and pseudoscience in clinical psychology (pp. 109–142). New York, NY: Guilford Press.

 

 

Notice that references for books and book chapters are similar to those for journal articles, but there are several differences too. For an edited book, the names of the editors appear with their first and middle initials followed by their last names (not the other way around)—with the abbreviation “Eds.” (or “Ed.,” if there is only one) appearing in parentheses immediately after the final editor’s name. Only the first word of a book title is capitalized (with the exceptions noted for article titles), and the entire title is italicized. For a chapter in an edited book, the page numbers of the chapter appear in parentheses after the book title with the abbreviation “pp.” Finally, both formats end with the location of publication and the publisher, separated by a colon.

Reference Citations

 

When you refer to another researcher’s idea, you must include a reference citation (in the text) to the work in which that idea originally appeared and a full reference to that work in the reference list. What counts as an idea that must be cited? In general, this includes phenomena discovered by other researchers, theories they have developed, hypotheses they have derived, and specific methods they have used (e.g., specific questionnaires or stimulus materials). Citations should also appear for factual information that is not common knowledge so that other researchers can check that information for themselves. For example, in an article on the effect of cell phone usage on driving ability, the writer might cite official statistics on the number of cell phone–related accidents that occur each year. Among the ideas that do not need citations are widely shared methodological and statistical concepts (e.g., between- subjects design, t test) and statements that are so broad that they would be difficult for anyone to argue with (e.g., “Working memory plays a role in many daily activities.”). Be careful, though, because “common knowledge” about human behavior is often incorrect. Therefore, when in doubt, find an appropriate reference to cite or remove the questionable assertion.

When you cite a work in the text of your manuscript, there are two ways to do it. Both include only the last names of the authors and the year of publication. The first method is to use the authors’ last names in the sentence (with no first names or initials) followed immediately by the year of publication in parentheses. Here are some examples:

 

Burger (2008) conducted a replication of Milgram’s (1963) original obedience study.

 

 

Although many people believe that women are more talkative than men, Mehl, Vazire, Ramirez-Esparza, Slatcher, and Pennebaker (2007) found essentially no difference in the number of words spoken by male and female college students.

 

Notice several things. First, the authors’ names are treated grammatically as names of people, not as things. It is better to write “a replication of Milgram’s (1963) study” than “a replication of Milgram (1963).” Second, when there are two authors the names are not separated by commas, but when there are three or more authors they are. Third, the word and (rather than an ampersand) is used to join the authors’ names. Fourth, the year follows immediately after the final author’s name. An additional point, which is not illustrated in these examples but is illustrated in the sample paper in Section 11.2 “Writing a Research Report in American Psychological Association (APA) Style”, is that the year only needs to be included the first time a particular work is cited in the same paragraph.

 

The second way to cite an article or a book chapter is parenthetically—including the authors’ last names and the year of publication in parentheses following the idea that is being credited. Here are some examples:

 

People can be surprisingly obedient to authority figures (Burger, 2008; Milgram, 1963).

 

 

Recent evidence suggests that men and women are similarly talkative (Mehl, Vazire, Ramirez-Esparza, Slatcher, & Pennebaker, 2007).

 

One thing to notice about such parenthetical citations is that they are often placed at the end of the sentence, which minimizes their disruption to the flow of that sentence. In contrast to the first way of citing a work, this way always includes the year—even when the citation is given multiple times in the

 

 

same paragraph. Notice also that when there are multiple citations in the same set of parentheses, they are organized alphabetically by the name of the first author and separated by semicolons.

 

There are no strict rules for deciding which of the two citation styles to use. Most articles and book chapters contain a mixture of the two. In general, however, the first approach works well when you want to emphasize the person who conducted the research—for example, if you were comparing the theories of two prominent researchers. It also works well when you are describing a particular study in detail. The second approach works well when you are discussing a general idea and especially when you want to include multiple citations for the same idea.

 

The third most common error in Table 11.2 “Top 10 APA Style Errors” has to do with the use of et al. This is an abbreviation for the Latin term et alia, which means “and others.” In APA style, if an article or a book chapter has more than two authors, you should include all their names when you first cite that work. After that, however, you should use the first author’s name followed by “et al.” Here are some examples:

 

Recall that Mehl et al. (2007) found that women and men spoke about the same number of words per day on average.

 

There is a strong positive correlation between the number of daily hassles and the number of symptoms people experience (Kanner et al., 1981).

 

Notice that there is no comma between the first author’s name and “et al.” Notice also that there is no period after “et” but there is one after “al.” This is because “et” is a complete word and “al.” is an abbreviation for the word alia.

 

K EY TAKE AWAYS

 

 

 

· APA style is a set of guidelines for writing in psychology. It is the genre of writing that psychologists use to communicate about their research with other researchers and practitioners.

· APA style can be seen as having three levels. There is the organization of a research article, the high-

level style that includes writing in a formal and straightforward way, and the low-level style that consists of many specific rules of grammar, spelling, formatting of references, and so on.

 

 

 

· References and reference citations are an important part of APA style. There are specific rules for formatting references and for citing them in the text of an article.

 

 

 

 

1. Practice: Find a description of a research study in a popular magazine, newspaper, blog, or website.

 

Then identify five specific differences between how that description is written and how it would be written in APA style.

2. Practice: Find and correct the errors in the following fictional APA-style references and citations.

11.2 Writing a Research Report in American Psychological Association (APA) Style

 

 

 

1. Identify the major sections of an APA-style research report and the basic contents of each section.

 

2. Plan and write an effective APA-style research report.

LEARNIN G OBJE CTIVE S

 

 

In this section, we look at how to write an APA-style empirical research report, an article that presents the results of one or more new studies. Recall that the standard sections of an empirical research report provide a kind of outline. Here we consider each of these sections in detail, including what information it contains, how that information is formatted and organized, and tips for writing each section. At the end of this section is a sample APA-style research report that illustrates many of these principles.

Sections of a Research Report

 

Title Page and Abstract

 

An APA-style research report begins with a title page. The title is centered in the upper half of the page, with each important word capitalized. The title should clearly and concisely (in about 12 words or fewer) communicate the primary variables and research questions. This sometimes requires a main title followed by a subtitle that elaborates on the main title, in which case the main title and subtitle are separated by a colon. Here are some titles from recent issues of professional journals published by the American Psychological Association.

 

· Sex Differences in Coping Styles and Implications for Depressed Mood

· Effects of Aging and Divided Attention on Memory for Items and Their Contexts

· Computer-Assisted Cognitive Behavioral Therapy for Child Anxiety: Results of a Randomized Clinical Trial

· Virtual Driving and Risk Taking: Do Racing Games Increase Risk-Taking Cognitions, Affect, and Behavior?

 

 

Below the title are the authors’ names and, on the next line, their institutional affiliation—the university or other institution where the authors worked when they conducted the research. As we have already seen, the authors are listed in an order that reflects their contribution to the research. When multiple authors have made equal contributions to the research, they often list their names alphabetically or in a randomly determined order.

 

Individuals’ First Impressions”

 

· “Don’t Hide Your Happiness! Positive Emotion Dissociation, Social Connectedness, and Psychological Functioning”

· “Forbidden Fruit: Inattention to Attractive Alternatives Provokes Implicit Relationship Reactance”

Individual researchers differ quite a bit in their preference for such titles. Some use them regularly, while

 

others never use them. What might be some of the pros and cons of using cute article titles?

“Through the Looking Glass Clearly: Accuracy and Assumed Similarity in Well-Adjusted

“Let’s Get Serious: Communicating Commitment in Romantic Relationships”





In some areas of psychology, the titles of many empirical research reports are informal in a way that is perhaps best described as “cute.” They usually take the form of a play on words or a well-known expression that relates to the topic under study. Here are some examples from recent issues of the

Journal of Personality and Social Psychology.

How Informal Should an Article Title Be?

It’s Soooo Cute!

 

 

For articles that are being submitted for publication, the title page also includes an author note that lists the authors’ full institutional affiliations, any acknowledgments the authors wish to make to agencies that funded the research or to colleagues who commented on it, and contact information for the authors. For student papers that are not being submitted for publication—including theses—author notes are generally not necessary.

 

 

The abstract is a summary of the study. It is the second page of the manuscript and is headed with the word Abstract. The first line is not indented. The abstract presents the research question, a summary of the method, the basic results, and the most important conclusions. Because the abstract is usually limited to about 200 words, it can be a challenge to write a good one.

Introduction

 

The introduction begins on the third page of the manuscript. The heading at the top of this page is the full title of the manuscript, with each important word capitalized as on the title page. The introduction includes three distinct subsections, although these are typically not identified by separate headings. The opening introduces the research question and explains why it is interesting, the literature review discusses relevant previous research, and the closing restates the research question and comments on the method used to answer it.

The Opening

 

The opening, which is usually a paragraph or two in length, introduces the research question and explains why it is interesting. To capture the reader’s attention, researcher Daryl Bem recommends starting with general observations about the topic under study, expressed in ordinary language (not technical jargon)—observations that are about people and their behavior (not about researchers or their research; Bem, 2003). [1] Concrete examples are often very useful here. According to Bem, this would be a poor way to begin a research report:

 

Festinger’s theory of cognitive dissonance received a great deal of attention during the latter part of the 20th century (p. 191)

 

The following would be much better:

 

 

The individual who holds two beliefs that are inconsistent with one another may feel uncomfortable. For example, the person who knows that he or she enjoys smoking but believes it to be unhealthy may experience discomfort arising from the inconsistency or disharmony between these two thoughts or cognitions. This feeling of discomfort was called cognitive dissonance by social psychologist Leon

 

 

Festinger (1957), who suggested that individuals will be motivated to remove this dissonance in whatever way they can (p. 191).

 

After capturing the reader’s attention, the opening should go on to introduce the research question and explain why it is interesting. Will the answer fill a gap in the literature? Will it provide a test of an important theory? Does it have practical implications? Giving readers a clear sense of what the research is about and why they should care about it will motivate them to continue reading the literature review—and will help them make sense of it.

 

Breaking the Rules

 

 

Researcher Larry Jacoby reported several studies showing that a word that people see or hear repeatedly can seem more familiar even when they do not recall the repetitions—and that this tendency is especially pronounced among older adults. He opened his article with the following humorous anecdote (Jacoby, 1999).

 

A friend whose mother is suffering symptoms of Alzheimer’s disease (AD) tells the story of taking her mother to visit a nursing home, preliminary to her mother’s moving there. During an orientation meeting at the nursing home, the rules and regulations were explained, one of which regarded the dining room.

The dining room was described as similar to a fine restaurant except that tipping was not required. The absence of tipping was a central theme in the orientation lecture, mentioned frequently to emphasize the quality of care along with the advantages of having paid in advance. At the end of the meeting, the friend’s mother was asked whether she had any questions. She replied that she only had one question: “Should I tip?” (p. 3).

 

Although both humor and personal anecdotes are generally discouraged in APA-style writing, this example is a highly effective way to start because it both engages the reader and provides an excellent real-world example of the topic under study.

The Literature Review

 

 

Immediately after the opening comes the literature review, which describes relevant previous research on the topic and can be anywhere from several paragraphs to several pages in length. However, the literature review is not simply a list of past studies. Instead, it constitutes a kind of argument for why the research question is worth addressing. By the end of the literature review, readers should be convinced that the research question makes sense and that the present study is a logical next step in the ongoing research process.

 

Like any effective argument, the literature review must have some kind of structure. For example, it might begin by describing a phenomenon in a general way along with several studies that demonstrate it, then describing two or more competing theories of the phenomenon, and finally presenting a hypothesis to test one or more of the theories. Or it might describe one phenomenon, then describe another phenomenon that seems inconsistent with the first one, then propose a theory that resolves the inconsistency, and finally present a hypothesis to test that theory. In applied research, it might describe a phenomenon or theory, then describe how that phenomenon or theory applies to some important real-world situation, and finally suggest a way to test whether it does, in fact, apply to that situation.

 

Looking at the literature review in this way emphasizes a few things. First, it is extremely important to start with an outline of the main points that you want to make, organized in the order that you want to make them. The basic structure of your argument, then, should be apparent from the outline itself.

Second, it is important to emphasize the structure of your argument in your writing. One way to do this is to begin the literature review by summarizing your argument even before you begin to make it. “In this article, I will describe two apparently contradictory phenomena, present a new theory that has the potential to resolve the apparent contradiction, and finally present a novel hypothesis to test the theory.” Another way is to open each paragraph with a sentence that summarizes the main point of the paragraph and links it to the preceding points. These opening sentences provide the “transitions” that many beginning researchers have difficulty with. Instead of beginning a paragraph by launching into a description of a previous study, such as “Williams (2004) found that…,” it is better to start by indicating something about why you are describing this particular study. Here are some simple examples:

 

Another example of this phenomenon comes from the work of Williams (2004).

 

 

Williams (2004) offers one explanation of this phenomenon.

 

 

An alternative perspective has been provided by Williams (2004). We used a method based on the one used by Williams (2004).

Finally, remember that your goal is to construct an argument for why your research question is interesting and worth addressing—not necessarily why your favorite answer to it is correct. In other words, your literature review must be balanced. If you want to emphasize the generality of a phenomenon, then of course you should discuss various studies that have demonstrated it. However, if there are other studies that have failed to demonstrate it, you should discuss them too. Or if you are proposing a new theory, then of course you should discuss findings that are consistent with that theory. However, if there are other findings that are inconsistent with it, again, you should discuss them too. It is acceptable to argue that

the balance of the research supports the existence of a phenomenon or is consistent with a theory (and that is usually the best that researchers in psychology can hope for), but it is not acceptable to ignore contradictory evidence. Besides, a large part of what makes a research question interesting is uncertainty about its answer.

The Closing

 

The closing of the introduction—typically the final paragraph or two—usually includes two important elements. The first is a clear statement of the main research question or hypothesis. This statement tends to be more formal and precise than in the opening and is often expressed in terms of operational definitions of the key variables. The second is a brief overview of the method and some comment on its appropriateness. Here, for example, is how Darley and Latané (1968) [2] concluded the introduction to their classic article on the bystander effect:

 

These considerations lead to the hypothesis that the more bystanders to an emergency, the less likely, or the more slowly, any one bystander will intervene to provide aid. To test this proposition it would be necessary to create a situation in which a realistic “emergency” could plausibly occur. Each subject should also be blocked from communicating with others to prevent his getting information about their behavior during the emergency. Finally, the experimental situation should allow for the assessment of the speed

and frequency of the subjects’ reaction to the emergency. The experiment reported below attempted to fulfill these conditions (p. 378).

 

Thus the introduction leads smoothly into the next major section of the article—the method section.

 

Method

 

The method section is where you describe how you conducted your study. An important principle for writing a method section is that it should be clear and detailed enough that other researchers could replicate the study by following your “recipe.” This means that it must describe all the important elements of the study—basic demographic characteristics of the participants, how they were recruited, whether they were randomly assigned, how the variables were manipulated or measured, how counterbalancing was accomplished, and so on. At the same time, it should avoid irrelevant details such as the fact that the study was conducted in Classroom 37B of the Industrial Technology Building or that the questionnaire was double-sided and completed using pencils.

 

The method section begins immediately after the introduction ends with the heading “Method” (not “Methods”) centered on the page. Immediately after this is the subheading “Participants,” left justified and in italics. The participants subsection indicates how many participants there were, the number of women and men, some indication of their age, other demographics that may be relevant to the study, and how they were recruited, including any incentives given for participation.

After the participants section, the structure can vary a bit. Figure 11.1 “Three Ways of Organizing an APA- Style Method” shows three common approaches. In the first, the participants section is followed by a design and procedure subsection, which describes the rest of the method. This works well for methods that are relatively simple and can be described adequately in a few paragraphs. In the second approach, the participants section is followed by separate design and procedure subsections. This works well when both the design and the procedure are relatively complicated and each requires multiple paragraphs.

 

What is the difference between design and procedure? The design of a study is its overall structure. What were the independent and dependent variables? Was the independent variable manipulated, and if so, was it manipulated between or within subjects? How were the variables operationally defined? The procedure is how the study was carried out. It often works well to describe the procedure in terms of what the participants did rather than what the researchers did. For example, the participants gave their informed consent, read a set of instructions, completed a block of four practice trials, completed a block of 20 test trials, completed two questionnaires, and were debriefed and excused.

 

In the third basic way to organize a method section, the participants subsection is followed by a materials subsection before the design and procedure subsections. This works well when there are complicated materials to describe. This might mean multiple questionnaires, written vignettes that participants read

 

 

and respond to, perceptual stimuli, and so on. The heading of this subsection can be modified to reflect its content. Instead of “Materials,” it can be “Questionnaires,” “Stimuli,” and so on.

Results

 

The results section is where you present the main results of the study, including the results of the statistical analyses. Although it does not include the raw data—individual participants’ responses or scores—researchers should save their raw data and make them available to other researchers who request them. Some journals now make the raw data available online.

 

Although there are no standard subsections, it is still important for the results section to be logically organized. Typically it begins with certain preliminary issues. One is whether any participants or responses were excluded from the analyses and why. The rationale for excluding data should be described clearly so that other researchers can decide whether it is appropriate. A second preliminary issue is how multiple responses were combined to produce the primary variables in the analyses. For example, if participants rated the attractiveness of 20 stimulus people, you might have to explain that you began by computing the mean attractiveness rating for each participant. Or if they recalled as many items as they could from study list of 20 words, did you count the number correctly recalled, compute the percentage correctly recalled, or perhaps compute the number correct minus the number incorrect? A third preliminary issue is the reliability of the measures. This is where you would present test-retest correlations, Cronbach’s α, or other statistics to show that the measures are consistent across time and across items. A final preliminary issue is whether the manipulation was successful. This is where you would report the results of any manipulation checks.

 

The results section should then tackle the primary research questions, one at a time. Again, there should be a clear organization. One approach would be to answer the most general questions and then proceed to answer more specific ones. Another would be to answer the main question first and then to answer secondary ones. Regardless, Bem (2003) [3] suggests the following basic structure for discussing each new result:

 

1. Remind the reader of the research question.

 

 

2. Give the answer to the research question in words.

 

3. Present the relevant statistics.

 

4. Qualify the answer if necessary.

 

5. Summarize the result.

 

 

Notice that only Step 3 necessarily involves numbers. The rest of the steps involve presenting the research question and the answer to it in words. In fact, the basic results should be clear even to a reader who skips over the numbers.

Discussion

 

The discussion is the last major section of the research report. Discussions usually consist of some combination of the following elements:

 

· Summary of the research

· Theoretical implications

· Practical implications

· Limitations

· Suggestions for future research

 

The discussion typically begins with a summary of the study that provides a clear answer to the research question. In a short report with a single study, this might require no more than a sentence. In a longer report with multiple studies, it might require a paragraph or even two. The summary is often followed by a discussion of the theoretical implications of the research. Do the results provide support for any existing theories? If not, how can they be explained? Although you do not have to provide a definitive explanation or detailed theory for your results, you at least need to outline one or more possible explanations. In applied research—and often in basic research—there is also some discussion of the practical implications of the research. How can the results be used, and by whom, to accomplish some real-world goal?

 

The theoretical and practical implications are often followed by a discussion of the study’s limitations. Perhaps there are problems with its internal or external validity. Perhaps the manipulation was not very effective or the measures not very reliable. Perhaps there is some evidence that participants did not fully

 

 

understand their task or that they were suspicious of the intent of the researchers. Now is the time to discuss these issues and how they might have affected the results. But do not overdo it. All studies have limitations, and most readers will understand that a different sample or different measures might have produced different results. Unless there is good reason to think they would have, however, there is no reason to mention these routine issues. Instead, pick two or three limitations that seem like they could have influenced the results, explain how they could have influenced the results, and suggest ways to deal with them.

 

Most discussions end with some suggestions for future research. If the study did not satisfactorily answer the original research question, what will it take to do so? What new research questions has the study raised? This part of the discussion, however, is not just a list of new questions. It is a discussion of two or three of the most important unresolved issues. This means identifying and clarifying each question, suggesting some alternative answers, and even suggesting ways they could be studied.

 

Finally, some researchers are quite good at ending their articles with a sweeping or thought-provoking conclusion. Darley and Latané (1968), [4] for example, ended their article on the bystander effect by discussing the idea that whether people help others may depend more on the situation than on their personalities. Their final sentence is, “If people understand the situational forces that can make them hesitate to intervene, they may better overcome them” (p. 383). However, this kind of ending can be difficult to pull off. It can sound overreaching or just banal and end up detracting from the overall impact of the article. It is often better simply to end when you have made your final point (although you should avoid ending on a limitation).

References

 

The references section begins on a new page with the heading “References” centered at the top of the page. All references cited in the text are then listed in the format presented earlier. They are listed alphabetically by the last name of the first author. If two sources have the same first author, they are listed alphabetically by the last name of the second author. If all the authors are the same, then they are listed chronologically by the year of publication. Everything in the reference list is double-spaced both within and between references.

 

 

Appendixes, Tables, and Figures

 

Appendixes, tables, and figures come after the references. An appendix is appropriate for supplemental material that would interrupt the flow of the research report if it were presented within any of the major sections. An appendix could be used to present lists of stimulus words, questionnaire items, detailed descriptions of special equipment or unusual statistical analyses, or references to the studies that are included in a meta-analysis. Each appendix begins on a new page. If there is only one, the heading is “Appendix,” centered at the top of the page. If there is more than one, the headings are “Appendix A,” “Appendix B,” and so on, and they appear in the order they were first mentioned in the text of the report.

 

After any appendixes come tables and then figures. Tables and figures are both used to present results. Figures can also be used to illustrate theories (e.g., in the form of a flowchart), display stimuli, outline procedures, and present many other kinds of information. Each table and figure appears on its own page. Tables are numbered in the order that they are first mentioned in the text (“Table 1,” “Table 2,” and so on). Figures are numbered the same way (“Figure 1,” “Figure 2,” and so on). A brief explanatory title, with the important words capitalized, appears above each table. Each figure is given a brief explanatory caption, where (aside from proper nouns or names) only the first word of each sentence is capitalized.

More details on preparing APA-style tables and figures are presented later in the book.

 

Sample APA-Style Research Report

 

Figure 11.2 “Title Page and Abstract”, Figure 11.3 “Introduction and Method”,Figure 11.4 “Results and Discussion”, and Figure 11.5 “References and Figure” show some sample pages from an APA-style empirical research report originally written by undergraduate student Tomoe Suyama at California State University, Fresno. The main purpose of these figures is to illustrate the basic organization and formatting of an APA-style empirical research report, although many high-level and low-level style conventions can be seen here too.

· An APA-style empirical research report consists of several standard sections. The main ones are the abstract, introduction, method, results, discussion, and references.

· The introduction consists of an opening that presents the research question, a literature review that describes previous research on the topic, and a closing that restates the research question and comments on the method. The literature review constitutes an argument for why the current study is worth doing.

· The method section describes the method in enough detail that another researcher could replicate the study. At a minimum, it consists of a participants subsection and a design and procedure subsection.

· The results section describes the results in an organized fashion. Each primary result is presented in terms of statistical results but also explained in words.

· The discussion typically summarizes the study, discusses theoretical and practical implications and

limitations of the study, and offers suggestions for further research.

LEARNIN G OBJE CT IVE S

 

 

Writing an empirical research report in American Psychological Association (APA) style is only one way to present new research in psychology. In this section, we look at several other important ways.

Other Types of Manuscripts

 

Section 11.2 “Writing a Research Report in American Psychological Association (APA) Style” focused on writing empirical research reports to be submitted for publication in a professional journal. However, there are other kinds of manuscripts that are written in APA style, many of which will not be submitted for publication elsewhere. Here we look at a few of them.

Review and Theoretical Articles

 

Recall that review articles summarize research on a particular topic without presenting new empirical results. When these articles present a new theory, they are often called theoretical articles. Review and theoretical articles are structured much like empirical research reports, with a title page, an abstract, references, appendixes, tables, and figures, and they are written in the same high-level and low-level style. Because they do not report the results of new empirical research, however, there is no method or results section. Of course, the body of the manuscript should still have a logical organization and include an opening that identifies the topic and explains its importance, a literature review that organizes previous research (identifying important relationships among concepts or gaps in the literature), and a closing or conclusion that summarizes the main conclusions and suggests directions for further research or discusses theoretical and practical implications. In a theoretical article, of course, much of the body of the

 

 

manuscript is devoted to presenting the new theory. Theoretical and review articles are usually divided into sections, each with a heading that is appropriate to that section. The sections and headings can vary considerably from article to article (unlike in an empirical research report). But whatever they are, they should help organize the manuscript and make the argument clear.

Final Manuscripts

 

Until now, we have focused on the formatting of manuscripts that will be submitted to a professional journal for publication. These are referred to as copy manuscripts. Many features of a copy manuscript—consistent double-spacing, the running head, and the placement of tables and figures at the end—are intended to make it easier to edit and typeset on its way to publication. The published journal article looks quite different from the copy manuscript. For example, the title and author information, the abstract, and the beginning of the introduction generally appear on the same page rather than on separate pages. In contrast, other types of manuscripts are prepared by the author in their final form with no intention of submitting them for publication elsewhere. These are called final manuscripts and include dissertations, theses, and other student papers.

 

Final manuscripts can differ from copy manuscripts in a number of ways that make them easier to read. This can include putting tables and figures close to where they are discussed so that the reader does not have to flip to the back of the manuscript to see them. It can also include variations in line spacing that improve readability—such as using single spacing for table titles and figure captions or triple spacing between major sections or around tables and figures. Dissertations and theses can differ from copy manuscripts in additional ways. They may have a longer abstract, a special acknowledgments page, a table of contents, and so on. For student papers, it is important to check with the course instructor about formatting specifics. In a research methods course, papers are usually required to be written as though they were copy manuscripts being submitted for publication.

Conference Presentations

 

One of the ways that researchers in psychology share their research with each other is by presenting it at professional conferences. (Although some professional conferences in psychology are devoted

 

 

mainly to issues of clinical practice, we are concerned here with those that focus on research.) Professional conferences can range from small-scale events involving a dozen researchers who get together for an afternoon to large-scale events involving thousands of researchers who meet for several days. Although researchers attending a professional conference are likely to discuss their work with each other informally, there are two more formal types of presentation: oral presentations (“talks”) and posters. Presenting a talk or poster at a conference usually requires submitting an abstract of the research to the conference organizers in advance and having it accepted for presentation—although the peer review process is typically not as rigorous as it is for manuscripts submitted to a professional journal.

Oral Presentations

 

In an oral presentation, or “talk,” the presenter stands in front of an audience of other researchers and tells them about his or her research—usually with the help of a slide show. Talks usually last from 10 to 20 minutes, with the last few minutes reserved for questions from the audience. At larger conferences, talks are typically grouped into sessions lasting an hour or two in which all the talks are on the same general topic.

 

In preparing a talk, presenters should keep several general principles in mind. The first is that the number of slides should be no more than about one per minute of the talk. The second is that a talk is generally structured like an APA-style research report. There is a slide with the title and authors, a few slides to help provide the background, a few more to help describe the method, a few for the results, and a few for the conclusions. The third is that the presenter should look at the audience members and speak to them in a conversational tone that is less formal than APA-style writing but more formal than a conversation with a friend. The slides should not be the focus of the presentation; they should act as visual aids. As such, they should present main points in bulleted lists or simple tables and figures.

Posters

 

 

Another way to present research at a conference is in the form of a poster. A poster is typically presented during a one- to two-hour poster session that takes place in a large room at the conference site.

Presenters set up their posters on bulletin boards arranged around the room and stand near them. Other researchers then circulate through the room, read the posters, and talk to the presenters. In essence, poster sessions are a grown-up version of the school science fair. But there is nothing childish about them. Posters are used by professional researchers in all scientific disciplines and they are becoming increasingly common. At a recent American Psychological Society Conference, nearly 2,000 posters were presented across 16 separate poster sessions. Among the reasons posters are so popular is that they encourage meaningful interaction among researchers.

 

Although a poster can consist of several sheets of paper that are attached separately to the bulletin board, it is now more common for them to consist of a single large sheet of paper. Either way, the information is organized into distinct sections, including a title, author names and affiliations, an introduction, a method section, a results section, a discussion or conclusions section, references, and acknowledgments. Although posters can include an abstract, this may not be necessary because the poster itself is already a brief summary of the research. Figure 11.7 “Two Possible Ways to Organize the Information on a Poster” shows two different ways that the information on a poster might be organized.

 

Figure 11.7 Two Possible Ways to Organize the Information on a Poster

 

 

 

 

 

Given the conditions under which posters are often presented—for example, in crowded ballrooms where people are also eating, drinking, and socializing—they should be constructed so that they present the main ideas behind the research in as simple and clear a way as possible. The font sizes on a poster should be large—perhaps 72 points for the title and authors’ names and 28 points for the main text. The information

 

 

should be organized into sections with clear headings, and text should be blocked into sentences or bulleted points rather than paragraphs. It is also better for it to be organized in columns and flow from top to bottom rather than to be organized in rows that flow across the poster. This makes it easier for multiple people to read at the same time without bumping into each other. Posters often include elements that add visual interest. Figures can be more colorful than those in an APA-style manuscript. Posters can also include copies of visual stimuli, photographs of the apparatus, or a simulation of participants being tested. They can also include purely decorative elements, although it is best not to overdo these.

 

Again, a primary reason that posters are becoming such a popular way to present research is that they facilitate interaction among researchers. Many presenters immediately offer to describe their research to visitors and use the poster as a visual aid. At the very least, it is important for presenters to stand by their posters, greet visitors, offer to answer questions, and be prepared for questions and even the occasional critical comment. It is generally a good idea to have a more detailed write-up of the research available for visitors who want more information, to offer to send them a detailed write-up, or to provide contact information so that they can request more information later.

· Talks and posters at professional conferences follow some APA style guidelines but are considerably less detailed than APA-style research reports. Their function is to present new research to interested

researchers and facilitate further interaction among researchers.

Ethical Standards in Psychology

July 9, 2025/in Psychology Questions /by Besttutor

Address each point in this paper. Please use grading rubric as an outline and cover every aspect in its entirety! Must include in-text citations. Original work ONLY NO PLAIGARISM!!

In a 7- to 10-page scholarly research paper, evaluate one of the enforceable standards in the Ethics Code (Standard 2: Competency) that can be found on pages 340-353 as it applies to an area of your specialization (I/O Psychology). The enforceable standards are in the second section of the book, Chapters 4–13. Along with the text, use a minimum of five scholarly articles taken from peer-reviewed journals. (To be Attached)

In the paper, you should evaluate the Ethics Code and how each section on the standard you chose will affect the ethical decision-making as it applies to your chosen topic. (The ethical standard that I have chosen is Standard 2 Competency)- you would cover each of the substandard within that Ethical Standard. A good approach is to do the following:

-Present each substandard in order. Briefly describe the substandard.

– Present examples of how that substandard relates to your specialization (my specialization is I/O Psychology).

Assignment: Application of Role Theory to a Case Study

July 9, 2025/in Psychology Questions /by Besttutor

This week, you will use role theory to apply to your chosen case study. In other words, your theoretical orientation—or lens—is role theory as you analyze the case study.

Use the same case study that you chose in Week 2. (Remember, you will be using this same case study throughout the entire course). Use the “Dissecting a Theory and Its Application to a Case Study” worksheet to help you dissect the theory. You do not need to submit this handout. It is a tool for you to use to dissect the theory, and then you can employ the information in the table to complete your assignment.

To prepare:

  • Review and focus on the same case study that you used in Week 2.
  • Review the websites and guides for developing PowerPoint skills found in the Learning Resources.
  • Record presentation using CaptureSpace.

By Day 7

Submit a narrated PowerPoint presentation using Kaltura Media that includes 11 to 12 slides.

  • Each slide should be written using bullet points, meaning no long paragraphs of written text should be in the slides.
  • Include a brief narration of less than 30 seconds for each slide (i.e., the narration takes the place of any written paragraphs, while the bullet points provide context and cues for the audience to follow along).

Your presentation should address the following:

  • Identify the presenting problem for the case study you selected. (Remember the presenting problem has to be framed from the perspective of role theory. For example, the presenting problem can be framed within the context of role functioning).
  • Identify all the relevant roles assumed by the client.
  • Analyze the social expectations and social and cultural norms revolving around the role, social position, and role scripts of one of the roles assumed by the client.
  • Explain the role and social position of the social worker in working with the client in the case study.
  • Describe how the role(s) and social position(s) assumed by the social worker will influence the relationship between the social worker and the client.
  • Identify three assessment questions that are guided by role theory that you will ask the client to better understand the problem.
  • Identify and describe two interventions that are aligned with the presenting problem and role theory.
  • Identify one outcome that you would measure if you were to evaluate one of the interventions you would implement to determine if the intervention is effective.
  • Evaluate one advantage and one limitation in using role theory in understanding the case.

Be sure to:

  • Identify and correctly reference the case study you have chosen.
  • Use literature to support your claims.
  • Use APA formatting and style.
  • Include the reference list on the last slide.

Hey Everyone!

 

Congrats on making it to the end even though we didn’t have a choice �.

The scenario we were placed with made me think about the career path I chose. In the scenario, an elderly woman was recently diagnosed with depression and generalized anxiety disorder. As a nurse, I would love to provide the patient’s family with information about the psychological disorder their family member is faced with and reassure them. Psychological disorders describe behavior and predict future behaviors (How Theories Are Used in Psychology,2020). I believe the two psychological theories that can help us to understand the disorders better are cognitive theories and social psychology theories. Being away from her family (hospitalized), may have contributed to her depression and anxiety. The change of environment correlates to the social psychology theory. The scenario also stated that the 75-year-old woman suffered from

dementia. Dementia (forgetfulness) correlates to the psychological cognitive theory.

In addition to informing the family members about the psychological disorder, as a nurse, I would also suggest putting pictures of her family members in the room or anything that will make her feel like home.

Regina,

The cognitive theory of psychology and the social theory of psychology can be tied into this scenario, as you have stated above. You gave a great example of each. Cognitive development can continue throughout our lives but it can also deteriorate (Feldman, 2018). Dementia is an example of how cognitive functions can decay over time. Dementia leads to decrease of neurotransmitters, like serotonin, dopamine, and norepinephrine. These neurotransmitters are precisely connected to our state of mind and tranquility based on the amount that is produces (Budson, 2019). Do you think this could cause the depression and anxiety as well?

Hey Nicolle!

Thank you for responding. I definitely think dementia can cause depression and anxiety. I can only imagine not being able to remember stuff/ people that I’m supposed to remember. It would defiantly take a toll on me. I would get anxious when people come to visit. As you stated, dementia leads to a decrease of neurotransmitters, like serotonin, dopamine, and norepinephrine and those are some of the “happy hormones”.

Hello Professor Owens and classmates,

This week we are applying our knowledge to a scenario presented in the discussion. The knowledge of psychological principles can help a great deal in nursing. In the scenario given above, the nurse’s knowledge of psychotherapy and biomedical therapy can help her begin a discussion with the patient and her family on what is the best course of action in her case. The family needs to be explained that professional care can and will aid the patient in faster recovery.

According to Feldman (2018), there are four major approaches to therapy: psychodynamic, behavioral, cognitive, and humanistic. Psychodynamic therapy includes seeking out the unresolved issues from the unconscious to conscious so that the patient can deal with the current state more effectively. This approach originated from Freud’s psychoanalytic theories of personality. The patient may also benefit from behavioral treatment, which is built upon the assumption that abnormal and normal behavior are both learned, therefore, the patient can be taught to respond more positively to her new environment. The cognitive approach to therapy can guide the patient to modify the way she thinks about herself and her environment versus changing her external behavior. Cognitive treatments seek to alter the patient’s thought patterns that lead to being stuck in dysfunctional ways of thinking (Feldman, 2018). This approach has proven to be successful in dealing with a wide range of disorders like anxiety, depression, eating disorders, and substance abuse. Additionally, combining cognitive approach with other types of therapies, for example, behavioral, can be an even more effective form of treatment.

According to De Vries and Timmins (2017), psychology is a required element in nursing education. It helps to get a better understanding of colleagues, patients, and health care organizations in general. Applying the knowledge of psychological principles helps optimize the care provided by nurses. Psychology provides the problem-solving support that is needed so much, not just in the profession of nursing but in everyday life. It helps achieve mastery in nursing practice and develop strong values and standards.

Hello Professor,

As a future nurse, having this knowledge of psychological principles will help me in the workplace, with patients and co-workers by allowing to me to have a better understanding of how the mind functions. I have gained a variety of information that can give me different perspectives on how and why my co-workers and patients behave they way they do. I will be handle situations in a professional manner rather than with just my emotions. This course has given me not only an understanding of how others work but also myself. I cannot force others to change their behavior but I can change mine and how I react to the behaviors of others. This scenario would be difficult for me to understand before this course, now I can give some insight on it. The diagnosis over generalized anxiety disorder does not come as a shock to me. Generalized anxiety disorder happens when an individual encounters longstanding, incessant anxiety and unmanageable concern (Feldman, 2018). Some factors of the cause can be easily recognized like family, money, work or health. Other times the individual has a sensation of impending doom but cannot pinpoint the purpose. This elderly lady, I believe has the generalized anxiety disorder because of her dementia. Her dementia can be interfering with her ability to understand her hospitalization therefore causing her to worry over her situation. Her family has stated that they are about her overall well-being. Due to her hospitalization her family believes that it is causing her stress as well. Her overall well-being potentially being an issue could be caused by the stress and anxiety she is feeling. If stress is dealt with inadequately it could cause adverse side effects, including psychological disorders (Feldman, 2018). My understanding of these psychological principles would help me in this scenario. I would be able to reassure her family that she is being well taken care of and explain to them how stress could be affecting her overall well-being. I would be able to give her proper coping skills to handle the stress she is experiencing. This course has provided me with valuable knowledge that I can utilize in my future endeavors.

Hello Nicolle,

I agree with you that this course has been very valuable for us as future nursing professionals. The material and the information we have learned will not only help us with our work life but also our personal lives. It was great to learn about problem-focused, and emotion-focused coping, a combination of the two coping strategies along with a healthy diet, exercise, mindfulness techniques, and meditation will help us deal with stress ourselves as well as make suggestions to patients.

Hello Everyone!

 

Scenario Congratulations! You have graduated from Chamberlain University and have been working as a nurse for one year. On your next shift, you are tasked with taking care of a 75-year-old woman who is suffering from dementia. She is under your care and has been recently diagnosed with depression and generalized anxiety disorder. Her family comes to visit her often and expresses to you that they are worried about her overall health and have been overly stressed making sure she gets the proper care she needs. The family has also stated that they believe the recent hospitalization is contributing to her stress.

Answer the following questions based on the scenario described above:

As a future nurse, I will apply the following concepts throughout my career. I feel that utilizing behavioral and cognitive concepts are very important. I feel in the case above this is important to be able to help this patient and her family feel comfortable with you taking care of her. These concepts can also help the patient with all of her needs weather it is giving her medications or just sitting with her and letting her talk. When it comes to being a nurse you have to conform and act in an appropriate manner in order to gain the trust of the patients, their families, and your coworkers This will also show future colleagues and bosses that you are trustworthy and can act in a professional manner. Another concept that is beneficial in this profession is humanistic which in this case can help the 75-year-old patient with dementia reduce her stress and give her a better more

Discuss two to three major theories or concepts that you have learned throughout the course and apply them to the case. Creativity in application is encouraged! As a future nurse, how will having an understanding of psychological principles help you in the workplace, with patients and co-workers?

Amanda,

I completely agree with that the behavioral approach can help in this scenario. The behavioral approach conveys that concentration should be surface behavior that can been seen and be gauged neutrally, rather than behavior that is within (Feldman, 2018). Along with visible behavior, this approach is interested in how circumstantial components influence the visible behavior. Behavioral therapy is an effective way to treat patients with dementia. It instructs the caretakers to watch for causes that bring about the symptoms and then maintain them when they are noticed (Sauer, 2019). What circumstantial component in this scenario could be influencing her observable symptoms of dementia?

Hey Amanda!

Thank you for sharing your thoughts on the scenario. I think you’re absolutely right on the humanistic approach with the patient. Another approach for the patient could be a cognitive theory approach because of her dementia.

Hi Everyone

The importance of psychology in the nursing profession is almost natural for nurses. If a nurse has ever needed to try analyze how their patient thinks and feels in order to better understand how to care for them effectively, the application of psychology in nursing is evident (Hana, 2018). Psychology and nursing careers go hand-in-hand, and this approach allows the healthcare professional to build a trusting relationship with the patient to provide the appropriate care and when it comes to a scenario whereby a 75 years old patient who is suffering from dementia and recently diagnosed with depression and generalized anxiety disorder, the question will be as a nurse, what kind of psychological theories or concepts can I apply on this patient to better understand and analyze what is going with her since psychology goes in hand with nursing. To the best of my knowledge, I will start by applying biological theory in psychology which states that all thoughts, feeling & behavior ultimately have a biological cause ( MCLeod, 2013). It is one of the major perspectives in psychology that involves studying of the brain, genetics, hormones, the immune and nervous systems which I believe biological perspective best describes the human behavior because, psychological issues can be studied to understand human behavior. There are various studies that can be done, such as the study of the nervous system, the immune system, the brain and genetics. Genetics as it is known to pass down from generations, one can conclude that certain behavioral patterns are predictable for future generations and I will start by analyzing what types of dementia can be genetically or inherited and also what could be possibly the cause of her brain damage which tends to interferes with the ability of her brain cells to communicate with each other which thereby affecting her thinking, behavior and feelings which also can be affected. Other theory I will be looking at is Cognitive perspective which suggests that people’s thoughts and beliefs are central components of abnormal behavior. (Feldman, 2018). Since dementia is a neuropsychiatric syndrome that is characterized by cognitive decline and progressive deterioration of daily functioning, commonly associated with behavioral and psychological symptoms of dementia BPSD (Abraha et al, 2017). As a nurse, I will be looking at what kind of cognitive therapy does she need which will serves as an intervention for treatment such as reality orientation and skills training which seem to be an effective interventions for reversing cognitive impairment.

Psychology as a behavioral health discipline is the key to the biopsychosocial practice, and plays a major role in understanding the concept of health and illness( Saeed, 2005). As a nurse, I will apply psychological perspectives in many areas such that the principles of psychology will enable me to assess, evaluate and provide solutions to all unwanted emotional situations as patient depends on nurses to reduce their emotional stress, as biological functioning and structure determines one’s behavior and as a nurse, the biological understanding of how my patients will be my priority by monitoring their well being and in terms of my co- worker’s, I will apply behavioral control such that I will engage in Speaking up, confronting co-workers, and communicating expectations and perceptions of undesired behavior are important to team and organizational performance (Qi and Liu, 2017) Reacting poorly to conflict can lead to regret, resentment and rifts. On the other hand, I will learn to manage conflict well, so that my professional relationships with my co-workers will become stronger than ever.

When I met Yolanda and Jay one fall in my child development class, Yolanda was just two months pregnant. Approaching age 30, married for several years, and their careers well under way, they had decided to have a baby. To prepare for parenthood, they enrolled in my evening section, arriving once a week after work full of questions: “How does the baby grow before birth?” “When is each organ formed?” “Has its heart begun to beat?” “Can it hear, feel, or sense our presence?”

Most of all, Yolanda and Jay wanted to do everything possible to make sure their baby would be born healthy. Yolanda started to wonder about her diet and whether she should keep up her daily aerobic workout. And she asked me whether an aspirin for a headache, a glass of wine at dinner, or a few cups of coffee during work and study hours might be harmful.

In this chapter, we answer Yolanda and Jay’s questions, along with a great many more that scientists have asked about the events before birth. First, we trace prenatal development, paying special attention to environmental supports for healthy growth, as well as damaging influences that threaten the child’s health and survival. Next, we turn to the events of childbirth. Today, women in industrialized nations have many choices about where and how they give birth, and hospitals go to great lengths to make the arrival of a new baby a rewarding, family-centered event.

Yolanda and Jay’s son Joshua reaped the benefits of his parents’ careful attention to his needs during pregnancy. He was strong, alert, and healthy at birth. Nevertheless, the birth process does not always go smoothly. We will consider the pros and cons of medical interventions, such as pain-relieving drugs and surgical deliveries, designed to ease a difficult birth and protect the health of mother and baby. Our discussion also addresses the development of infants born underweight or too early. We conclude with a close look at the remarkable capacities of newborns.

Prenatal Development

The sperm and ovum that unite to form the new individual are uniquely suited for the task of reproduction. The ovum is a tiny sphere, measuring 1175 inch in diameter—barely visible to the naked eye as a dot the size of the period at the end of this sentence. But in its microscopic world, it is a giant—the largest cell in the human body. The ovum’s size makes it a perfect target for the much smaller sperm, which measure only 1500 inch.

Conception

About once every 28 days, in the middle of a woman’s menstrual cycle, an ovum bursts from one of her ovaries, two walnut-sized organs located deep inside her abdomen, and is drawn into one of two fallopian tubes—long, thin structures that lead to the hollow, soft-lined uterus (see  Figure 3.1 ). While the ovum is traveling, the spot on the ovary from which it was released, now called the corpus luteum, secretes hormones that prepare the lining of the uterus to receive a fertilized ovum. If pregnancy does not occur, the corpus luteum shrinks, and the lining of the uterus is discarded two weeks later with menstruation.

The male produces sperm in vast numbers—an average of 300 million a day—in the testes, two glands located in the scrotum, sacs that lie just behind the penis. In the final process of maturation, each sperm develops a tail that permits it to swim long distances, upstream in the female reproductive tract, through the cervix (opening of the uterus) and into the fallopian tube, where fertilization usually takes place. The journey is difficult, and many sperm die. Only 300 to 500 reach the ovum, if one happens to be present. Sperm live for up to 6 days and can lie in wait for the ovum, which survives for only 1 day after being released into the fallopian tube. However, most conceptions result from intercourse occurring during a three-day period—on the day of ovulation or during the 2 days preceding it (Wilcox, Weinberg, & Baird,  1995 ).

With conception, the story of prenatal development begins to unfold. The vast changes that take place during the 38 weeks of pregnancy are usually divided into three phases: (1) the period of the zygote, (2) the period of the embryo, and (3) the period of the fetus. As we look at what happens in each, you may find it useful to refer to  Table 3.1 , which summarizes milestones of prenatal development.

Period of the Zygote

FIGURE 3.1 Female reproductive organs, showing fertilization, early cell duplication, and implantation.

(From Before We Are Born, 6th ed., by K. L. Moore & T. V. N. Persaud, p. 87. Copyright © 2003, reprinted with permission from Elsevier, Inc.)

The period of the zygote lasts about two weeks, from fertilization until the tiny mass of cells drifts down and out of the fallopian tube and attaches itself to the wall of the uterus. The zygote’s first cell duplication is long and drawn out; it is not complete until about 30 hours after conception. Gradually, new cells are added at a faster rate. By the fourth day, 60 to 70 cells exist that form a hollow, fluid-filled ball called a blastocyst (refer again to  Figure 3.1 ). The cells on the inside, called the embryonic disk, will become the new organism; the outer ring of cells, termed the trophoblast, will become the structures that provide protective covering and nourishment.

  The one-celled zygote multiplies and forms a blastocyst.

The blastocyst burrows into the uterine lining. Structures that feed and protect the developing organism begin to form—amnion, chorion, yolk sac, placenta, and umbilical cord.

A primitive brain and spinal cord appear. Heart, muscles, ribs, backbone, and digestive tract begin to develop.

Many external body structures (face, arms, legs, toes, fingers) and internal organs form. The sense of touch begins to develop, and the embryo can move.

  Fetus

9–12 3 inches (7.6 cm); less than 1 ounce (28 g) Rapid increase in size begins. Nervous system, organs, and muscles become organized and connected, and new behavioral capacities (kicking, thumb sucking, mouth opening, and rehearsal of breathing) appear. External genitals are well-formed, and the fetus’s sex is evident.
Second image4 13–24 12 inches (30 cm); 1.8 pounds (820 g) The fetus continues to enlarge rapidly. In the middle of this period, fetal movements can be felt by the mother. Vernix and lanugo keep the fetus’s skin from chapping in the amniotic fluid. Most of the brain’s neurons are in place by 24 weeks. Eyes are sensitive to light, and the fetus reacts to sound.
Third image5 25–38 20 inches (50 cm); 7.5 pounds (3,400 g) The fetus has a good chance of survival if born during this time. Size increases. Lungs mature. Rapid brain development causes sensory and behavioral capacities to expand. In the middle of this period, a layer of fat is added under the skin. Antibodies are transmitted from mother to fetus to protect against disease. Most fetuses rotate into an upside-down position in preparation for birth.

Implantation.

Between the seventh and ninth days,  implantation  occurs: The blastocyst burrows deep into the uterine lining. Surrounded by the woman’s nourishing blood, it starts to grow in earnest. At first, the trophoblast (protective outer layer) multiplies fastest. It forms a membrane, called the  amnion , that encloses the developing organism in amniotic fluid, which helps keep the temperature of the prenatal world constant and provides a cushion against any jolts caused by the woman’s movement. A yolk sac emerges that produces blood cells until the liver, spleen, and bone marrow are mature enough to take over this function (Moore, Persaud, & Torchia,  2013 ).

The events of these first two weeks are delicate and uncertain. As many as 30 percent of zygotes do not survive this period. In some, the sperm and ovum do not join properly. In others, cell duplication never begins. By preventing implantation in these cases, nature eliminates most prenatal abnormalities (Sadler,  2010 ).

Period of the zygote: seventh to ninth day. The fertilized ovum duplicates rapidly, forming a hollow ball of cells, or blastocyst, by the fourth day after fertilization. Here the blastocyst, magnified thousands of times, burrows into the uterine lining between the seventh and ninth day.

The Placenta and Umbilical Cord.

By the end of the second week, cells of the trophoblast form another protective membrane—the  chorion , which surrounds the amnion. From the chorion, tiny hairlike villi, or blood vessels, emerge. 1  As these villi burrow into the uterine wall, the placenta starts to develop. By bringing the embryo’s and mother’s blood close together, the  placenta  permits food and oxygen to reach the organism and waste products to be carried away. A membrane forms that allows these substances to be exchanged but prevents the mother’s and embryo’s blood from mixing directly.

The placenta is connected to the developing organism by the  umbilical cord , which first appears as a tiny stalk and, during the course of pregnancy, grows to a length of 1 to 3 feet. The umbilical cord contains one large vein that delivers blood loaded with nutrients and two arteries that remove waste products. The force of blood flowing through the cord keeps it firm, so it seldom tangles while the embryo, like a space-walking astronaut, floats freely in its fluid-filled chamber (Moore, Persaud, & Torchia,  2013 ).

By the end of the period of the zygote, the developing organism has found food and shelter. These dramatic beginnings take place before most mothers know they are pregnant.

Period of the Embryo

The period of the  embryo  lasts from implantation through the eighth week of pregnancy. During these brief six weeks, the most rapid prenatal changes take place as the groundwork is laid for all body structures and internal organs.

Last Half of the First Month.

In the first week of this period, the embryonic disk forms three layers of cells: (1) the ectoderm, which will become the nervous system and skin; (2) the mesoderm, from which will develop the muscles, skeleton, circulatory system, and other internal organs; and (3) the endoderm, which will become the digestive system, lungs, urinary tract, and glands. These three layers give rise to all parts of the body.

At first, the nervous system develops fastest. The ectoderm folds over to form the  neural tube , or primitive spinal cord. At 3½ weeks, the top swells to form the brain. While the nervous system is developing, the heart begins to pump blood, and the muscles, backbone, ribs, and digestive tract appear. At the end of the first month, the curled embryo—only ¼ inch long—consists of millions of organized groups of cells with specific functions.

The Second Month.

In the second month, growth continues rapidly. The eyes, ears, nose, jaw, and neck form. Tiny buds become arms, legs, fingers, and toes. Internal organs are more distinct: The intestines grow, the heart develops separate chambers, and the liver and spleen take over production of blood cells so that the yolk sac is no longer needed. Changing body proportions cause the embryo’s posture to become more upright.

Period of the embryo: fourth week. This 4-week-old embryo is only ¼-inch long, but many body structures have begun to form. The primitive tail will disappear by the end of the embryonic period.

1Recall from  Table 2.4  on  page 56  that chorionic villus sampling is the prenatal diagnostic method that can be performed earliest, at nine weeks after conception.

Period of the embryo: seventh week. The embryo’s posture is more upright. Body structures—eyes, nose, arms, legs, and internal organs—are more distinct. An embryo this age responds to touch. It can also move, although at less than one inch long and one ounce in weight, it is till too tiny to be felt by the mother.

At 7 weeks, production of neurons (nerve cells that store and transmit information) begins deep inside the neural tube at the astounding pace of more than 250,000 per minute (Nelson,  2011 ). Once formed, neurons begin traveling along tiny threads to their permanent locations, where they will form the major parts of the brain.

At the end of this period, the embryo—about 1 inch long and 17 ounce in weight—can already sense its world. It responds to touch, particularly in the mouth area and on the soles of the feet. And it can move, although its tiny flutters are still too light to be felt by the mother (Moore, Persaud, & Torchia,  2013 ).

Period of the Fetus

The period of the  fetus , from the ninth week to the end of pregnancy, is the longest prenatal period. During this “growth and finishing” phase, the organism increases rapidly in size.

The Third Month.

In the third month, the organs, muscles, and nervous system start to become organized and connected. When the brain signals, the fetus kicks, bends its arms, forms a fist, curls its toes, turns its head, opens its mouth, and even sucks its thumb, stretches, and yawns. Body position changes occur as often as 25 times per hour (Einspieler, Marschik, & Prechtl,  2008 ). The tiny lungs begin to expand and contract in an early rehearsal of breathing movements. By the twelfth week, the external genitals are well-formed, and the sex of the fetus can be detected with ultrasound (Sadler,  2010 ). Other finishing touches appear, such as fingernails, toenails, tooth buds, and eyelids. The heartbeat can now be heard through a stethoscope.

Prenatal development is sometimes divided into  trimesters , or three equal time periods. At the end of the third month, the first trimester is complete.

The Second Trimester.

By the middle of the second trimester, between 17 and 20 weeks, the new being has grown large enough that the mother can feel its movements. A white, cheeselike substance called  vernix  protects its skin from chapping during the long months spent bathing in the amniotic fluid. White, downy hair called  lanugo also appears over the entire body, helping the vernix stick to the skin.

At the end of the second trimester, many organs are well-developed. And most of the brain’s billions of neurons are in place; few will be produced after this time. However, glial cells, which support and feed the neurons, continue to increase rapidly throughout the remaining months of pregnancy, as well as after birth. Consequently, brain weight increases tenfold from the twentieth week until birth (Roelfsema et al.,  2004 ). At the same time, neurons begin forming synapses, or connections, at a rapid pace.

Period of the fetus: eleventh week. The fetus grows rapidly. At 11 weeks, the brain and muscles are better connected. The fetus can kick, bend its arms, and open and close its hands and mouth, and suck its thumb. Notice the yolk sac, which shrinks as the internal organs take over its function of producing blood cells.

Brain growth means new behavioral capacities. The 20-week-old fetus can be stimulated as well as irritated by sounds. And if a doctor looks inside the uterus using fetoscopy (see  Table 2.4  on  page 56 ), fetuses try to shield their eyes from the light with their hands, indicating that sight has begun to emerge (Moore, Persaud, & Torchia,  2013 ). Still, a fetus born at this time cannot survive. Its lungs are immature, and the brain cannot yet control breathing and body temperature.

The Third Trimester.

During the final trimester, a fetus born early has a chance for survival. The point at which the baby can first survive, called the  age of viability , occurs sometime between 22 and 26 weeks (Moore, Persaud, & Torchia,  2013 ). A baby born between the seventh and eighth months, however, usually needs oxygen assistance to breathe. Although the brain’s respiratory center is now mature, tiny air sacs in the lungs are not yet ready to inflate and exchange carbon dioxide for oxygen.

The brain continues to make great strides. The cerebral cortex, the seat of human intelligence, enlarges. As neural connectivity and organization improve, the fetus spends more time awake. At 20 weeks, fetal heart rate reveals no periods of alertness. But by 28 weeks, fetuses are awake about 11 percent of the time, a figure that rises to 16 percent just before birth (DiPietro et al.,  1996 ). Between 30 and 34 weeks, fetuses show rhythmic alternations between sleep and wakefulness that gradually increase in organization (Rivkees,  2003 ). Around this time, synchrony between fetal heart rate and motor activity peaks: A rise in heart rate is usually followed within 5 seconds by a burst of motor activity (DiPietro et al.,  2006 ). These are clear signs that coordinated neural networks are beginning to form in the brain.

Period of the fetus: twenty-second week. This fetus is almost one foot long and weighs slightly more than one pound. Its movements can be felt easily by the mother and by other family members who place a hand on her abdomen. If born now, the fetus has a slim chance of surviving.

By the end of pregnancy, the fetus also takes on the beginnings of a personality. Fetal activity is linked to infant temperament. In one study, more active fetuses during the third trimester became 1-year-olds who could better handle frustration and 2-year-olds who were less fearful, in that they more readily interacted with toys and with an unfamiliar adult in a laboratory (DiPietro et al.,  2002 ). Perhaps fetal activity is an indicator of healthy neurological development, which fosters adaptability in childhood. The relationships just described, however, are only modest. As we will see in  Chapter 6 , sensitive caregiving can modify the temperaments of children who have difficulty adapting to new experiences.

Period of the fetus: thirty-sixth week. This fetus fills the uterus. To nourish it, the umbilical cord and placenta have grown large. Notice the vernix (a cheeselike substance) on the skin, which protects it from chapping. The fetus has accumulated fat to aid temperature regulation after birth. In two more weeks, it will be full-term.

The third trimester brings greater responsiveness to stimulation. Between 23 and 30 weeks, connections form between the cerebral cortex and brain regions involved in pain sensitivity. By this time, painkillers should be used in any surgical procedures (Lee et al.,  2005 ). Around 28 weeks, fetuses blink their eyes in reaction to nearby sounds (Kisilevsky & Low,  1998 ; Saffran, Werker, & Werner,  2006 ). And at 30 weeks, fetuses presented with a repeated auditory stimulus against the mother’s abdomen initially react with a rise in heart rate and body movements. But over the next 5 to 6 minutes, responsiveness gradually declines, indicating habituation (adaptation) to the sound. If the stimulus is reintroduced after a 10-minute delay, heart rate falls off far more quickly (Dirix et al.,  2009 ). This suggests that fetuses can remember for at least a brief period.

Within the next six weeks, fetuses distinguish the tone and rhythm of different voices and sounds. They show systematic heart rate changes to a male versus a female speaker, to the mother’s voice versus a stranger’s, to a stranger speaking their native language (English) versus a foreign language (Mandarin Chinese), and to a simple familiar melody (descending tones) versus an unfamiliar melody (ascending tones) (Granier-Deferre et al.,  2003 ; Huotilainen et al.,  2005 ; Kisilevsky et al.,  2003 ,  2009 ; Lecanuet et al.,  1993 ). And in one clever study, mothers read aloud Dr. Seuss’s lively book The Cat in the Hat for the last six weeks of pregnancy. After birth, their infants learned to turn on recordings of the mother’s voice by sucking on nipples. They sucked hardest to hear The Cat in the Hat—the sound they had come to know while still in the womb (DeCasper & Spence, 1988).

In the final three months, the fetus gains more than 5 pounds and grows 7 inches. In the eighth month, a layer of fat is added to assist with temperature regulation. The fetus also receives antibodies from the mother’s blood that protect against illnesses, since the newborn’s own immune system will not work well until several months after birth. In the last weeks, most fetuses assume an upside-down position, partly because of the shape of the uterus and also because the head is heavier than the feet. Growth slows, and birth is about to take place.

ASK YOURSELF

REVIEW Why is the period of the embryo regarded as the most dramatic prenatal period? Why is the period of the fetus called the “growth and finishing” phase?

CONNECT How is brain development related to fetal capacities and behavior?

APPLY Amy, two months pregnant, wonders how the embryo is being fed and what parts of the body have formed. “I don’t look pregnant yet, so does that mean not much development has taken place?” she asks. How would you respond to Amy?

image6 Prenatal Environmental Influences

Although the prenatal environment is far more constant than the world outside the womb, many factors can affect the embryo and fetus. Yolanda and Jay learned that parents—and society as a whole—can do a great deal to create a safe environment for development before birth.

Teratogens

The term  teratogen  refers to any environmental agent that causes damage during the prenatal period.Scientists chose this label (from the Greek word teras, meaning “malformation” or “monstrosity”) because they first learned about harmful prenatal influences from cases in which babies had been profoundly damaged. But the harm done by teratogens is not always simple and straightforward. It depends on the following factors:

· ● Dose. As we discuss particular teratogens, you will see that larger doses over longer time periods usually have more negative effects.

· ● Heredity. The genetic makeup of the mother and the developing organism plays an important role. Some individuals are better able than others to withstand harmful environments.

· ● Other negative influences. The presence of several negative factors at once, such as additional teratogens, poor nutrition, and lack of medical care, can worsen the impact of a harmful agent.

· ● Age. The effects of teratogens vary with the age of the organism at time of exposure. To understand this last idea, think of the sensitive period concept introduced in  Chapter 1 . A sensitive period is a limited time span in which a part of the body or a behavior is biologically prepared to develop rapidly. During that time, it is especially sensitive to its surroundings. If the environment is harmful, then damage occurs, and recovery is difficult and sometimes impossible.

Figure 3.2  on  page 86  summarizes prenatal sensitive periods. In the period of the zygote, before implantation, teratogens rarely have any impact. If they do, the tiny mass of cells is usually so damaged that it dies. The embryonic period is the time when serious defects are most likely to occur because the foundations for all body parts are being laid down. During the fetal period, teratogenic damage is usually minor. However, organs such as the brain, ears, eyes, teeth, and genitals can still be strongly affected.

The effects of teratogens go beyond immediate physical damage. Some health effects are delayed and may not show up for decades. Furthermore, psychological consequences may occur indirectly, as a result of physical damage. For example, a defect resulting from drugs the mother took during pregnancy can affect others’ reactions to the child as well as the child’s ability to explore the environment. Over time, parent–child interaction, peer relations, and cognitive, emotional, and social development may suffer. Furthermore, prenatally exposed children may be less resilient in the face of environmental risks, such as single parenthood, parental emotional disturbance, or maladaptive parenting (Yumoto, Jacobson, & Jacobson,  2008 ). As a result, their long-term adjustment may be compromised.

FIGURE 3.2 Sensitive periods in prenatal development.

Each organ or structure has a sensitive period, during which its development may be disturbed. Blue horizontal bars indicate highly sensitive periods. Green horizontal bars indicate periods that are somewhat less sensitive to teratogens, although damage can occur.

(Adapted from Before We Are Born, 7th ed., by K. L. Moore and T. V. N. Persaud, p. 313. Copyright © 2008, reprinted with permission from Elsevier, Inc.)

Notice how an important idea about development discussed in earlier chapters is at work here: bidirectional influences between child and environment. Now let’s look at what scientists have discovered about a variety of teratogens.

Prescription and Nonprescription Drugs.

In the early 1960s, the world learned a tragic lesson about drugs and prenatal development. At that time, a sedative called thalidomide was widely available in Canada, Europe, and South America. When taken by mothers 4 to 6 weeks after conception, thalidomide produced gross deformities of the embryo’s arms and legs and, less frequently, damage to the ears, heart, kidneys, and genitals. About 7,000 infants worldwide were affected (Moore, Persaud, & Torchia,  2013 ). As children exposed to thalidomide grew older, many scored below average in intelligence. Perhaps the drug damaged the central nervous system directly. Or the child-rearing conditions of these severely deformed youngsters may have impaired their intellectual development.

Another medication, a synthetic hormone called diethylstilbestrol (DES), was widely prescribed between 1945 and 1970 to prevent miscarriages. As daughters of these mothers reached adolescence and young adulthood, they showed unusually high rates of cancer of the vagina, malformations of the uterus, and infertility. When they tried to have children, their pregnancies more often resulted in prematurity, low birth weight, and miscarriage than those of non-DES-exposed women. Young men showed an increased risk of genital abnormalities and cancer of the testes (Goodman, Schorge, & Greene,  2011 ; Hammes & Laitman,  2003 ).

Currently, the most widely used potent teratogen is a vitamin A derivative called Accutane (known by the generic name isotretinoin), prescribed to treat severe acne and taken by hundreds of thousands of women of childbearing age in industrialized nations. Exposure during the first trimester results in eye, ear, skull, brain, heart, and immune system abnormalities (Honein, Paulozzi, & Erickson,  2001 ). Accutane’s packaging warns users to avoid pregnancy by using two methods of birth control, but many women do not heed this advice (Garcia-Bournissen et al.,  2008 ).

Indeed, any drug with a molecule small enough to penetrate the placental barrier can enter the embryonic or fetal bloodstream. Yet many pregnant women continue to take over-the-counter medications without consulting their doctors. Aspirin is one of the most common. Several studies suggest that regular aspirin use is linked to low birth weight, infant death around the time of birth, poorer motor development, and lower intelligence scores in early childhood, although other research fails to confirm these findings (Barr et al.,  1990 ; Kozer et al.,  2003 ; Streissguth et al.,  1987 ). Coffee, tea, cola, and cocoa contain another frequently consumed drug, caffeine. High doses increase the risk of low birth weight (Brent, Christian, & Diener,  2011 ). And persistent intake of antidepressant medication is linked to an elevated incidence of premature delivery and birth complications, including respiratory distress, and to high blood pressure in infancy (Lund, Pedersen, & Henriksen,  2009 ; Roca et al.,  2011 ; Udechuku et al.,  2010 ).

Because children’s lives are involved, we must take findings like these seriously. At the same time, we cannot be sure that these frequently used drugs actually cause the problems just mentioned. Often mothers take more than one drug. If the embryo or fetus is injured, it is hard to tell which drug might be responsible or whether other factors correlated with drug taking are at fault. Until we have more information, the safest course of action is the one Yolanda took: Avoid these drugs entirely. Unfortunately, many women do not know that they are pregnant during the early weeks of the embryonic period, when exposure to medications (and other teratogens) can be of greatest threat.

Illegal Drugs.

The use of highly addictive mood-altering drugs, such as cocaine and heroin, has become more widespread, especially in poverty-stricken inner-city areas, where these drugs provide a temporary escape from a daily life of hopelessness. Nearly 4 percent of U.S. pregnant women take these substances (Substance Abuse and Mental Health Services Administration,  2011 ).

Babies born to users of cocaine, heroin, or methadone (a less addictive drug used to wean people away from heroin) are at risk for a wide variety of problems, including prematurity, low birth weight, physical defects, breathing difficulties, and death around the time of birth (Bandstra et al.,  2010 ; Howell, Coles, & Kable,  2008 ; Schuetze & Eiden,  2006 ). In addition, these infants are born drug-addicted. They are often feverish and irritable and have trouble sleeping, and their cries are abnormally shrill and piercing—a common symptom among stressed newborns (Bauer et al.,  2005 ). When mothers with many problems of their own must care for these babies, who are difficult to calm down, cuddle, and feed, behavior problems are likely to persist.

Throughout the first year, heroin- and methadone-exposed infants are less attentive to the environment than nonexposed babies, and their motor development is slow. After infancy, some children get better, while others remain jittery and inattentive. The kind of parenting they receive may explain why problems persist for some but not for others (Hans & Jeremy,  2001 ).

Evidence on cocaine suggests that some prenatally exposed babies develop lasting difficulties. Cocaine constricts the blood vessels, causing oxygen delivered to the developing organism to fall for 15 minutes following a high dose. It also can alter the production and functioning of neurons and the chemical balance in the fetus’s brain. These effects may contribute to an array of cocaine-associated physical defects, including eye, bone, genital, urinary tract, kidney, and heart deformities; brain hemorrhages and seizures; and severe growth retardation (Covington et al.,  2002 ; Feng,  2005 ; Salisbury et al.,  2009 ). Several studies report perceptual, motor, attention, memory, language, and impulse-control problems that persist into the preschool and school years (Bandstra et al.,  2011 ; Dennis et al.,  2006 ; Lester & Lagasse,  2010 ; Linares et al.,  2006 ).

This infant, born many weeks before his due date, breathes with the aid of a respirator. Prematurity and low birth weight can result from a variety of environmental influences during pregnancy, including maternal drug and tobacco use.

Other investigations, however, reveal no major negative effects of prenatal cocaine exposure (Behnke et al.,  2006 ; Frank et al.,  2005 ; Hurt et al.,  2009 ). These contradictory findings indicate how difficult it is to isolate the precise damage caused by illegal drugs. Cocaine users vary greatly in the amount, potency, and purity of the cocaine they ingest. Also, they often take several drugs, display other high-risk behaviors, suffer from poverty and other stresses, and engage in insensitive caregiving—factors that worsen outcomes for children (Jones,  2006 ). But researchers have yet to determine exactly what accounts for findings of cocaine-related damage in some studies but not in others.

Another illegal drug, marijuana, is used more widely than heroin and cocaine. Researchers have linked prenatal marijuana exposure to smaller head size (a measure of brain growth); attention, memory, and academic achievement difficulties; impulsivity and overactivity; and depression as well as anger and aggression in childhood and adolescence (Goldschmidt et al.,  2004 ; Gray et al.,  2005 ; Huizink & Mulder,  2006 ; Jutras-Aswad et al.,  2009 ). As with cocaine, however, lasting consequences are not well-established. Overall, the effects of illegal drugs are far less consistent than the impact of two legal substances to which we now turn: tobacco and alcohol.

Tobacco.

Although smoking has declined in Western nations, an estimated 14 percent of U.S. women smoke during their pregnancies (Tong et al.,  2009 ). The best-known effect of smoking during the prenatal period is low birth weight. But the likelihood of other serious consequences, such as miscarriage, prematurity, cleft lip and palate, blood vessel abnormalities, impaired heart rate and breathing during sleep, infant death, and asthma and cancer later in childhood, also increases (Geerts et al.,  2012 ; Howell, Coles, & Kable,  2008 ; Jaakkola & Gissler,  2004 ; Mossey et al.,  2009 ). The more cigarettes a mother smokes, the greater the chances that her baby will be affected. And if a pregnant woman stops smoking at any time, even during the third trimester, she reduces the likelihood that her infant will be born underweight and suffer from future problems (Klesges et al.,  2001 ).

Even when a baby of a smoking mother appears to be born in good physical condition, slight behavioral abnormalities may threaten the child’s development. Newborns of smoking mothers are less attentive to sounds, display more muscle tension, are more excitable when touched and visually stimulated, and more often have colic (persistent crying). These findings suggest subtle negative effects on brain development (Law et al.,  2003 ; Sondergaard et al.,  2002 ). Consistent with this view, prenatally exposed children and adolescents tend to have shorter attention spans, difficulties with impulsivity and overactivity, poorer memories, lower mental test scores, and higher levels of disruptive, aggressive behavior (Espy et al.,  2011 ; Fryer, Crocker, & Mattson,  2008 ; Lindblad & Hjern,  2010 ).

Exactly how can smoking harm the fetus? Nicotine, the addictive substance in tobacco, constricts blood vessels, lessens blood flow to the uterus, and causes the placenta to grow abnormally. This reduces the transfer of nutrients, so the fetus gains weight poorly. Also, nicotine raises the concentration of carbon monoxide in the bloodstreams of both mother and fetus. Carbon monoxide displaces oxygen from red blood cells, damaging the central nervous system and slowing body growth in the fetuses of laboratory animals (Friedman,  1996 ). Similar effects may occur in humans.

From one-third to one-half of nonsmoking pregnant women are “passive smokers” because their husbands, relatives, or co-workers use cigarettes. Passive smoking is also related to low birth weight, infant death, childhood respiratory illnesses, and possible long-term attention, learning, and behavior problems (Best,  2009 ; Pattenden et al.,  2006 ). Clearly, expectant mothers should avoid smoke-filled environments.

Alcohol.

In his moving book The Broken Cord, Michael Dorris ( 1989 ), a Dartmouth College anthropology professor, described what it was like to rear his adopted son Abel (called Adam in the book), whose biological mother drank heavily throughout pregnancy and died of alcohol poisoning shortly after his birth. A Sioux Indian, Abel was born with  fetal alcohol spectrum disorder (FASD) , a term that encompasses a range of physical, mental, and behavioral outcomes caused by prenatal alcohol exposure. Children with FASD are given one of three diagnoses, which vary in severity:

Left photo: This 5-year-old’s mother drank heavily during pregnancy. Her widely spaced eyes, thin upper lip, and flattened philtrum are typical of fetal alcohol syndrome (FAS). Right photo: This 12-year-old has the small head and facial abnormalities of FAS. She also shows the mental impairments and slow growth that accompany the disorder.

· 1. Fetal alcohol syndrome (FAS), distinguished by (a) slow physical growth, (b) a pattern of three facial abnormalities (short eyelid openings; a thin upper lip; a smooth or flattened philtrum, or indentation running from the bottom of the nose to the center of the upper lip), and (c) brain injury, evident in a small head and impairment in at least three areas of functioning—for example, memory, language and communication, attention span and activity level (overactivity), planning and reasoning, motor coordination, or social skills. Other defects—of the eyes, ears, nose, throat, heart, genitals, urinary tract, or immune system—may also be present. Abel was diagnosed as having FAS. As is typical for this disorder, his mother drank heavily throughout pregnancy.

· 2. Partial fetal alcohol syndrome (p-FAS), characterized by (a) two of the three facial abnormalities just mentioned and (b) brain injury, again evident in at least three areas of impaired functioning. Mothers of children with p-FAS generally drank alcohol in smaller quantities, and children’s defects vary with the timing and length of alcohol exposure. Furthermore, recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression (see  page 73  in  Chapter 2 ), thereby contributing to symptoms (Ouko et al.,  2009 ).

· 3. Alcohol-related neurodevelopmental disorder (ARND), in which at least three areas of mental functioning are impaired, despite typical physical growth and absence of facial abnormalities. Again, prenatal alcohol exposure, though confirmed, is less pervasive than in FAS (Chudley et al.,  2005 ; Loock et al.,  2005 ).

Even when provided with enriched diets, FAS babies fail to catch up in physical size during infancy and childhood. Mental impairment associated with all three FASD diagnoses is also permanent: In his teens and twenties, Abel Dorris had trouble concentrating and keeping a routine job, and he suffered from poor judgment. For example, he would buy something and not wait for change or would wander off in the middle of a task. He died at age 23, after being hit by a car.

The more alcohol a woman consumes during pregnancy, the poorer the child’s motor coordination, speed of information processing, reasoning, and intelligence and achievement test scores during the preschool and school years (Burden, Jacobson, & Jacobson,  2005 ; Korkman, Kettunen, & Autti-Raemoe,  2003 ; Mattson, Calarco, & Lang,  2006 ). In adolescence and early adulthood, FASD is associated with persisting attention and motor-coordination deficits, poor school performance, trouble with the law, inappropriate social and sexual behaviors, alcohol and drug abuse, and lasting mental health problems, including depression and high emotional reactivity to stress (Barr et al.,  2006 ; Fryer, Crocker, & Mattson,  2008 ; Hellemans et al.,  2010 ; Howell et al.,  2006 ; Streissguth et al.,  2004 ).

How does alcohol produce its devastating effects? First, it interferes with production and migration of neurons in the primitive neural tube. Brain-imaging research reveals reduced brain size, damage to many brain structures, and abnormalities in brain functioning, including the electrical and chemical activity involved in transferring messages from one part of the brain to another (Coles et al.,  2011 ; Haycock,  2009 ). Second, the body uses large quantities of oxygen to metabolize alcohol. A pregnant woman’s heavy drinking draws away oxygen that the developing organism needs for cell growth.

About 25 percent of U.S. mothers report drinking at some time during their pregnancies. As with heroin and cocaine, alcohol abuse is higher in poverty-stricken women. On some Native-American reservations, the incidence of FAS is as high as 10 to 20 percent (Szlemko, Wood, & Thurman,  2006 ; Tong et al.,  2009 ). Unfortunately, when affected girls later become pregnant, the poor judgment caused by the syndrome often prevents them from understanding why they themselves should avoid alcohol. Thus, the tragic cycle is likely to be repeated in the next generation.

How much alcohol is safe during pregnancy? Even mild drinking, less than one drink per day, is associated with reduced head size and body growth among children followed into adolescence (Jacobson et al.,  2004 ; Martinez-Frias et al.,  2004 ). Recall that other factors—both genetic and environmental—can make some fetuses more vulnerable to teratogens. Therefore, no amount of alcohol is safe. Couples planning a pregnancy and expectant mothers should avoid alcohol entirely.

This child’s deformities are linked to radiation exposure early in pregnancy, caused by the Chernobyl nuclear power plant disaster in 1986. She is also at risk for low intelligence and language and emotional disorders.

Radiation.

Defects due to ionizing radiation were tragically apparent in children born to pregnant women who survived the bombing of Hiroshima and Nagasaki during World War II. Similar abnormalities surfaced in the nine months following the 1986 Chernobyl, Ukraine, nuclear power plant accident. After each disaster, the incidence of miscarriage and babies born with underdeveloped brains, physical deformities, and slow physical growth rose dramatically (Double et al.,  2011 ; Schull,  2003 ). Evacuation of residents in areas near the Japanese nuclear facility damaged by the March 2011 earthquake and tsunami was intended to prevent these devastating outcomes.

Even when a radiation-exposed baby seems normal, problems may appear later. For example, even low-level radiation, resulting from industrial leakage or medical X-rays, can increase the risk of childhood cancer (Fattibene et al.,  1999 ). In middle childhood, prenatally exposed Chernobyl children had abnormal brain-wave activity, lower intelligence test scores, and rates of language and emotional disorders two to three times greater than those of nonexposed Russian children. Furthermore, the more tension parents reported, due to forced evacuation from their homes and worries about living in irradiated areas, the poorer their children’s emotional functioning (Loganovskaja & Loganovsky,  1999 ; Loganovsky et al.,  2008 ). Stressful rearing conditions seemed to combine with the damaging effects of prenatal radiation to impair children’s development.

Environmental Pollution.

In industrialized nations, an astounding number of potentially dangerous chemicals are released into the environment. More than 75,000 are in common use in the United States, and many new pollutants are introduced each year. When 10 newborns were randomly selected from U.S. hospitals for analysis of umbilical cord blood, researchers uncovered a startling array of industrial contaminants—287 in all (Houlihan et al.,  2005 ). They concluded that many babies are “born polluted” by chemicals that not only impair prenatal development but increase the chances of health problems and life-threatening diseases later on.

Certain pollutants cause severe prenatal damage. In the 1950s, an industrial plant released waste containing high levels of mercury into a bay providing seafood and water for the town of Minamata, Japan. Many children born at the time displayed physical deformities, mental retardation, abnormal speech, difficulty in chewing and swallowing, and uncoordinated movements. High levels of prenatal mercury exposure disrupt production and migration of neurons, causing widespread brain damage (Clarkson, Magos, & Myers,  2003 ; Hubbs-Tait et al.,  2005 ). Prenatal mercury exposure from maternal seafood diets predicts deficits in speed of cognitive processing and motor, attention, and verbal test performance during the school years (Boucher et al.,  2010 ; Debes et al.,  2006 ). Pregnant women are wise to avoid eating long-lived predatory fish, such as swordfish, albacore tuna, and shark, which are heavily contaminated with mercury.

For many years, polychlorinated biphenyls (PCBs) were used to insulate electrical equipment until research showed that, like mercury, they entered waterways and the food supply. In Taiwan, prenatal exposure to high levels of PCBs in rice oil resulted in low birth weight, discolored skin, deformities of the gums and nails, brain-wave abnormalities, and delayed cognitive development (Chen & Hsu,  1994 ; Chen et al.,  1994 ). Steady, low-level PCB exposure is also harmful. Women who frequently ate PCB-contaminated fish, compared with those who ate little or no fish, had infants with lower birth weights, smaller heads, persisting attention and memory difficulties, and lower intelligence test scores in childhood (Boucher, Muckle, & Bastien,  2009 ; Jacobson & Jacobson,  2003 ; Stewart et al.,  2008 ).

Another teratogen, lead, is present in paint flaking off the walls of old buildings and in certain materials used in industrial occupations. High levels of prenatal lead exposure are related to prematurity, low birth weight, brain damage, and a wide variety of physical defects. Even at low levels, affected infants and children show slightly poorer mental and motor development (Bellinger,  2005 ; Jedrychowski et al.,  2009 ).

Finally, prenatal exposure to dioxins—toxic compounds resulting from incineration—is linked to brain, immune system, and thyroid damage in babies and to an increased incidence of breast and uterine cancers in women, perhaps through altering hormone levels (ten Tusscher & Koppe,  2004 ). Even tiny amounts of dioxin in the paternal bloodstream cause a dramatic change in sex ratio of offspring: Affected men father nearly twice as many girls as boys (Ishihara et al.,  2007 ). Dioxin seems to impair the fertility of Y-bearing sperm prior to conception.

Infectious Disease.

About 5 percent of women in industrialized nations catch an infectious disease while pregnant. Although most of these illnesses, such as the common cold, seem to have no impact, a few—as  Table 3.2  illustrates—can cause extensive damage.

Viruses.

In the mid-1960s, a worldwide epidemic of rubella (three-day, or German, measles) led to the birth of more than 20,000 American babies with serious defects and to 13,000 fetal and newborn deaths. Consistent with the sensitive-period concept, the greatest damage occurs when rubella strikes during the embryonic period. More than 50 percent of infants whose mothers become ill during that time show deafness; eye deformities, including cataracts; heart, genital, urinary, intestinal, bone, and dental defects; and mental retardation. Infection during the fetal period is less harmful, but low birth weight, hearing loss, and bone defects may still occur. The organ damage inflicted by prenatal rubella often leads to lifelong health problems, including severe mental illness, diabetes, cardiovascular disease, and thyroid and immune-system dysfunction in adulthood (Brown,  2006 ; Duszak,  2009 ).

Routine vaccination in infancy and childhood has made new rubella outbreaks unlikely in industrialized nations. But an estimated 100,000 cases of prenatal infection continue to occur worldwide, primarily in developing countries in Africa and Asia with weak or absent immunization programs (Bale,  2009 ).

The human immunodeficiency virus (HIV), which can lead to acquired immune deficiency syndrome (AIDS), a disease that destroys the immune system, has infected increasing numbers of women over the past three decades. In developing countries, where 95 percent of new infections occur, more than half affect women. In South Africa, for example, nearly 30 percent of all pregnant women are HIV-positive (South African Department of Health,  2009 ). Untreated HIV-infected expectant mothers pass the deadly virus to the developing organism 20 to 30 percent of the time.

AIDS progresses rapidly in infants. By 6 months, weight loss, diarrhea, and repeated respiratory illnesses are common. The virus also causes brain damage, as indicated by seizures, gradual loss in brain weight, and delayed mental and motor development. Nearly half of prenatal AIDS babies die by 1 year of age and 90 percent by age 3 (Devi et al.,  2009 ). Antiretroviral drug therapy reduces prenatal AIDS transmission by as much as 95 percent, with no harmful consequences of drug treatment for children. These medications have led to a dramatic decline in prenatally acquired AIDS in Western nations. Although distribution is increasing, antiretroviral drugs are still not widely available in impoverished regions of the world (UNICEF,  2010a ).

As  Table 3.2  reveals, the developing organism is especially sensitive to the family of herpes viruses, for which no vaccine or treatment exists. Among these, cytomegalovirus (the most frequent prenatal infection, transmitted through respiratory or sexual contact) and herpes simplex 2 (which is sexually transmitted) are especially dangerous. In both, the virus invades the mother’s genital tract, infecting babies either during pregnancy or at birth.

Babies are tested for the HIV virus in a clinic in Mozambique, Africa. Prenatal treatment with antiretroviral drugs reduces transmission of AIDS from mother to child by as much as 95 percent.

Bacterial and Parasitic Diseases.

Table 3.2  also includes several bacterial and parasitic diseases. Among the most common is toxoplasmosis, caused by a parasite found in many animals. Pregnant women may become infected from eating raw or undercooked meat or from contact with the feces of infected cats. About 40 percent of women who have the disease transmit it to the developing organism. If it strikes during the first trimester, it is likely to cause eye and brain damage. Later infection is linked to mild visual and cognitive impairments (Jones, Lopez, & Wilson,  2003 ). Expectant mothers can avoid toxoplasmosis by making sure that the meat they eat is well-cooked, having pet cats checked for the disease, and turning over the care of litter boxes to other family members.

Other Maternal Factors

Besides avoiding teratogens, expectant parents can support the development of the embryo and fetus in other ways. In healthy, physically fit women, regular moderate exercise, such as walking, swimming, biking, or an aerobic workout, is related to increased birth weight (Olson et al.,  2009 ). However, frequent, vigorous exercise, especially late in pregnancy, results in lower birth weight than in healthy, nonexercising controls (Clapp et al.,  2002 ; Leet & Flick,  2003 ). Most women, however, do not engage in sufficient moderate exercise during pregnancy to promote their own and their baby’s health (Poudevigne & O’Connor,  2006 ). An expectant mother who remains fit experiences fewer physical discomforts in the final weeks.

In the following sections, we examine other maternal factors—nutrition, emotional stress, blood type, age, and previous births.

Nutrition.

During the prenatal period, when children are growing more rapidly than at any other time, they depend totally on the mother for nutrients. A healthy diet that results in a weight gain of 25 to 30 pounds (10 to 13.5 kilograms) helps ensure the health of mother and baby.

Prenatal malnutrition can cause serious damage to the central nervous system. The poorer the mother’s diet, the greater the loss in brain weight, especially if malnutrition occurred during the last trimester. During that time, the brain is increasing rapidly in size, and a maternal diet high in all the basic nutrients is necessary for it to reach its full potential. An inadequate diet during pregnancy can also distort the structure of the liver, kidney, pancreas, and other organs, resulting in lifelong health problems, including cardiovascular disease and diabetes in adulthood (Barker,  2008 ; Whincup et al.,  2008 ).

Because poor nutrition suppresses development of the immune system, prenatally malnourished babies frequently catch respiratory illnesses (Chandra,  1991 ). In addition, they are often irritable and unresponsive to stimulation. In poverty-stricken families, these effects quickly combine with a stressful home life. With age, low intelligence and serious learning problems become more apparent (Pollitt,  1996 ).

Many studies show that providing pregnant women with adequate food has a substantial impact on the health of their newborn babies. Yet the growth demands of the prenatal period require more than just increased quantity of food. Vitamin–mineral enrichment is also crucial. For example, taking a folic acid supplement around the time of conception greatly reduces by more than 70 percent abnormalities of the neural tube, such as anencephaly and spina bifida (see  Table 2.4  on  page 56 ). Folic acid supplementation early in pregnancy also reduces the risk of other physical defects, including cleft lip and palate, urinary tract abnormalities, and limb deformities. Furthermore, adequate folic acid intake during the last 10 weeks of pregnancy cuts in half the risk of premature delivery and low birth weight (Goh & Koren,  2008 ; MCR Vitamin Study Research Group,  1991 ; Scholl, Hediger, & Belsky,  1996 ).

Because of these findings, U.S. government guidelines recommend that all women of childbearing age consume 0.4 milligrams of folic acid per day. For women who have previously had a pregnancy affected by neural tube defect, the recommended amount is 4 to 5 milligrams (dosage must be carefully monitored, as excessive intake can be harmful) (American Academy of Pediatrics,  2006 ). About half of U.S. pregnancies are unplanned, so government regulations mandate that bread, flour, rice, pasta, and other grain products be fortified with folic acid.

When poor nutrition persists throughout pregnancy, infants usually require more than dietary improvement. Successful interventions must also break the cycle of apathetic mother–baby interactions. Some do so by teaching parents how to interact effectively with their infants, while others focus on stimulating infants to promote active engagement with their physical and social surroundings (Grantham-McGregor et al.,  1994 ; Grantham-McGregor, Schofield, & Powell,  1987 ).

Although prenatal malnutrition is highest in poverty-stricken regions of the world, it is not limited to developing countries. The U.S. Special Supplemental Food Program for Women, Infants, and Children (WIC), which provides food packages to low-income pregnant women, reaches about 90 percent of those who qualify because of their extremely low incomes (U.S. Department of Agriculture,  2011b ). But many U.S. women who need nutrition intervention are not eligible for WIC.

Emotional Stress.

When women experience severe emotional stress during pregnancy, their babies are at risk for a wide variety of difficulties. Intense anxiety—especially during the first two trimesters—is associated with higher rates of miscarriage, prematurity, low birth weight, infant respiratory and digestive illnesses, colic (persistent infant crying), sleep disturbances, and irritability during the child’s first three years (Field,  2011 ; Lazinski, Shea, & Steiner,  2008 ; van der Wal, van Eijsden, & Bonsel,  2007 ).

How can maternal stress affect the fetus?  TAKE A MOMENT … To understand this process, list the changes you sensed in your own body the last time you were under stress. When we experience fear and anxiety, stress hormones released into our bloodstream—such as epinephrine (adrenaline) and cortisol, known as the “flight or fight” hormones—cause us to be “poised for action.” Large amounts of blood are sent to parts of the body involved in the defensive response—the brain, the heart, and the muscles in the arms, legs, and trunk. Blood flow to other organs, including the uterus, is reduced. As a result, the fetus is deprived of a full supply of oxygen and nutrients.

Maternal stress hormones also cross the placenta, causing a dramatic rise in fetal stress hormones (evident in the amniotic fluid) and, therefore, in fetal heart rate, blood pressure, blood glucose, and activity level (Kinsella & Monk,  2009 ; Weinstock,  2008 ). Excessive fetal stress may permanently alter fetal neurological functioning, thereby heightening stress reactivity in later life. In several studies, infants and children of mothers who experienced severe prenatal anxiety displayed cortisol levels that were either abnormally high or abnormally low, both of which signal reduced physiological capacity to manage stress. Consistent with these findings, such children are more upset than their agemates when faced with novel or challenging experiences—effects that persist into adolescence and early adulthood (Entringer et al.,  2009 ; Van den Bergh et al.,  2008 ).

Furthermore, maternal emotional stress during pregnancy predicts childhood weakened immune system functioning and increased susceptibility to infectious disease (Nielsen et al.,  2011 ). It is also associated with diverse negative behavioral outcomes, including anxiety, short attention span, anger, aggression, overactivity, and lower mental test scores, above and beyond the impact of other risks, such as maternal prenatal maternal smoking, low birth weight, postnatal maternal anxiety, and low SES (de Weerth & Buitelaar,  2005 ; Gutteling et al.,  2006 ; Lazinski, Shea, & Steiner,  2008 ; Loomans et al.,  2011 ).

But stress-related prenatal complications are greatly reduced when mothers have partners, other family members, and friends who offer social support (Glover, Bergman, & O’Connor,  2008 ). The relationship of social support to positive pregnancy outcomes and subsequent child development is particularly strong for low-income women, who often lead highly stressful lives (see the  Social Issues: Health  box on  page 94 ).

Rh Factor Incompatibility.

When inherited blood types of mother and fetus differ, serious problems sometimes result. The most common cause of these difficulties is  Rh factor incompatibility . When the mother is Rh-negative (lacks the Rh blood protein) and the father is Rh-positive (has the protein), the baby may inherit the father’s Rh-positive blood type. If even a little of a fetus’s Rh-positive blood crosses the placenta into the Rh-negative mother’s bloodstream, she begins to form antibodies to the foreign Rh protein. If these enter the fetus’s system, they destroy red blood cells, reducing the oxygen supply to organs and tissues. Mental retardation, miscarriage, heart damage, and infant death can occur.

It takes time for the mother to produce Rh antibodies, so firstborn children are rarely affected. The danger increases with each additional pregnancy. Fortunately, Rh incompatibility can be prevented in most cases. After the birth of each Rh-positive baby, Rh-negative mothers are routinely given a vaccine to prevent the buildup of antibodies.

Maternal Age.

In  Chapter 2 , we noted that women who delay childbearing until their thirties or forties face increased risk of infertility, miscarriage, and babies born with chromosomal defects. Are other pregnancy complications more common for older mothers? Research indicates that healthy women in their thirties have about the same rates as those in their twenties (Bianco et al.,  1996 ; Dildy et al.,  1996 ; Prysak, Lorenz, & Kisly,  1995 ). Thereafter, as  Figure 3.3  reveals, complication rates increase, with a sharp rise among women age 50 to 55—an age at which because of menopause (end of menstruation) and aging reproductive organs, few women can conceive naturally (Salihu et al.,  2003 ; Usta & Nassar,  2008 ).

In the case of teenage mothers, does physical immaturity cause prenatal complications? As we will see in  Chapter 11 , nature tries to ensure that once a girl can conceive, she is physically ready to carry and give birth to a baby. Infants born to teenagers have a higher rate of problems, but not directly because of maternal age. Most pregnant teenagers come from low-income backgrounds, where stress, poor nutrition, and health problems are common. Also, many are afraid to seek medical care or, in the United States, do not have access to care because they lack health insurance (U.S. Department of Health and Human Services,  2011a ).

FIGURE 3.3 Relationship of maternal age to prenatal and birth complications.

Complications increase after age 40, with a sharp rise between 50 and 55 years. See  page 95  for a description of preeclampsia.

Social Issues: Health The Nurse–Family Partnership: Reducing Maternal Stress and Enhancing Child Development Through Social Support

At age 17, Denise—an unemployed high-school dropout living with her disapproving parents—gave birth to Tara. Having no one to turn to for help during pregnancy and beyond, Denise felt overwhelmed and anxious much of the time. Tara was premature and cried uncontrollably, slept erratically, and suffered from frequent minor illnesses throughout her first year. When she reached school age, she had trouble keeping up academically, and her teachers described her as distractible, unable to sit still, angry, and uncooperative.

The Nurse–Family Partnership, currently implemented in hundreds of counties across 42 U.S. states, is a voluntary home visiting program for first-time, low-income expectant mothers like Denise. Its goals are to reduce pregnancy and birth complications, promote competent early caregiving, and improve family conditions, thereby protecting children from lasting adjustment difficulties. A registered nurse visits the home weekly during the first month after enrollment, twice a month during the remainder of pregnancy and through the middle of the child’s second year, and then monthly until age 2. In these sessions, the nurse provides the mother with intensive social support—a sympathetic ear; assistance in accessing health and other community services and the help of family members (especially fathers and grandmothers); and encouragement to finish high school, find work, and engage in future family planning.

To evaluate the program’s effectiveness, researchers randomly assigned large samples of mothers at risk for high prenatal stress (due to teenage pregnancy, poverty, and other negative life conditions) to nurse-visiting or comparison conditions (just prenatal care, or prenatal care plus infant referral for developmental problems). Families were followed through their child’s school-age years and, in one experiment, into adolescence (Kitzman et al.,  2010 ; Olds et al.,  2004 ,  2007 ; Rubin et al.,  2011 ).

As kindergartners, Nurse–Family Partnership children obtained higher language and intelligence test scores. And at both ages 6 and 9, the children of home-visited mothers in the poorest mental health during pregnancy exceeded comparison children in academic achievement and displayed fewer behavior problems. Furthermore, from their baby’s birth on, home-visited mothers were on a more favorable life course: They had fewer subsequent births, longer intervals between their first and second births, more frequent contact with the child’s father, more stable intimate partnerships, less welfare dependence, and a greater sense of control over their lives—key factors in reducing subsequent prenatal stress and in protecting children’s development. Perhaps for these reasons, 12-year-old children of home-visited mothers continued to be advantaged in academic achievement and reported less alcohol use and drug-taking than comparison-group agemates.

Other findings revealed that professional nurses, compared with trained paraprofessionals, were far more effective in preventing outcomes associated with prenatal stress, including high infant fearfulness to novel stimuli and delayed mental development (Olds et al.,  2002 ). Nurses were probably more proficient in individualizing program guidelines to fit the strengths and challenges faced by each family. They also might have had unique legitimacy as experts in the eyes of stressed mothers, more easily convincing them to take steps to reduce pregnancy complications that can trigger persisting developmental problems—such as those Tara displayed.

The Nurse–Family Partnership is highly cost-effective (Dawley, Loch, & Bindrich,  2007 ). For $1 spent, it saves more than $5 in public spending on pregnancy complications, preterm births, and child and youth learning and behavior problems.

The Nurse–Family Partnership provides this first-time mother with regular home visits from a registered nurse. In follow-up research, children of home-visited mothers developed more favorably—cognitively, emotionally, and socially—than comparison children.

The Importance of Prenatal Health Care

Yolanda had her first prenatal appointment three weeks after missing her menstrual period. After that, she visited the doctor’s office once a month until she was seven months pregnant, then twice during the eighth month. As birth grew near, Yolanda’s appointments increased to once a week. The doctor kept track of her general health, her weight gain, the capacity of her uterus and cervix to support the fetus, and the fetus’s growth.

Yolanda’s pregnancy, like most others, was free of complications. But unexpected difficulties can arise, especially if mothers have health problems. For example, the 5 percent of pregnant women who have diabetes need careful monitoring. Extra glucose in the diabetic mother’s bloodstream causes the fetus to grow larger than average, making pregnancy and birth problems more common. Maternal high blood glucose also compromises prenatal brain development: It is linked to poorer memory and learning in infancy and early childhood (deRegnier et al.,  2007 ). Another complication, experienced by 5 to 10 percent of pregnant women, is preeclampsia (sometimes called toxemia), in which blood pressure increases sharply and the face, hands, and feet swell in the last half of pregnancy. If untreated, preeclampsia can cause convulsions in the mother and fetal death. Usually, hospitalization, bed rest, and drugs can lower blood pressure to a safe level (Vidaeff, Carroll, & Ramin,  2005 ). If not, the baby must be delivered at once.

Unfortunately, 6 percent of pregnant women in the United States wait until after the first trimester to seek prenatal care or receive none at all. Inadequate care is far more common among adolescent and low-income, ethnic-minority mothers. Their infants are three times as likely to be born underweight and five times as likely to die as are babies of mothers who receive early medical attention (Child Trends,  2012 ). Although the poorest of these mothers are eligible for government-sponsored health services, many low-income women do not qualify. As we will see when we take up birth complications, in nations where affordable medical care is universally available, such as Australia, Canada, Japan, and European countries, late-care pregnancies and maternal and infant health problems are greatly reduced.

LOOK AND LISTEN

List prenatal environmental factors that can compromise later academic performance and social adjustment. Ask several adults who hope someday to be parents to explain what they know about each factor. How great is their need for prenatal education?

During a routine prenatal visit, this couple views an ultrasound image of their twins. All pregnant women need regular prenatal care to protect their health and that of their babies.

Besides financial hardship, some mothers have other reasons for not seeking early prenatal care. These include situational barriers (difficulty finding a doctor, getting an appointment, and arranging transportation) and personal barriers (psychological stress, the demands of taking care of other young children, family crises, and ambivalence about the pregnancy). Many also engage in high-risk behaviors, such as smoking and drug abuse, which they do not want to reveal to health professionals (Daniels, Noe, & Mayberry,  2006 ; Maupin et al.,  2004 ). These women, who receive little or no prenatal care, are among those who need it most!

Clearly, public education about the importance of early and sustained prenatal care for all pregnant women is badly needed. Refer to Applying What We Know on  page 96 , which lists “do’s and don’ts” for a healthy pregnancy, based on our discussion of the prenatal environment.

Applying What We Know Do’s and Don’ts for a Healthy Pregnancy

Do Don’t
Do make sure that you have been vaccinated against infectious diseases that are dangerous to the embryo and fetus, such as rubella, before you get pregnant. Most vaccinations are not safe during pregnancy.

Do see a doctor as soon as you suspect that you are pregnant, and continue to get regular medical checkups throughout pregnancy.

Do eat a well-balanced diet and take vitamin–mineral supplements, as prescribed by your doctor, both prior to and during pregnancy. Gain 25 to 30 pounds gradually.

Do obtain literature from your doctor, library, or bookstore about prenatal development. Ask your doctor about anything that concerns you.

Do keep physically fit through moderate exercise. If possible, join a special exercise class for expectant mothers.

Do avoid emotional stress. If you are a single expectant mother, find a relative or friend on whom you can rely for emotional support.

Do get plenty of rest. An overtired mother is at risk for pregnancy complications.

Do enroll in a prenatal and childbirth education class with your partner or other companion. When parents know what to expect, the nine months before birth can be one of the most joyful times of life.

Don’t take any drugs without consulting your doctor.

Don’t smoke. If you have already smoked during part of your pregnancy, cut down or, better yet, quit. If other members of your family smoke, ask them to quit or to smoke outside.

Don’t drink alcohol from the time you decide to get pregnant.

Don’t engage in activities that might expose your embryo or fetus to environmental hazards, such as radiation or chemical pollutants. If you work in an occupation that involves these agents, ask for a safer assignment or a leave of absence.

Don’t engage in activities that might expose your embryo or fetus to harmful infectious diseases, such as toxoplasmosis.

Don’t choose pregnancy as a time to go on a diet.

Don’t gain too much weight during pregnancy. A very large weight gain is associated with complications.

image7 Childbirth

Although Yolanda and Jay completed my course three months before their baby was born, both agreed to return the following spring to share their experiences with my next class. Two-week-old Joshua came along as well. Yolanda and Jay’s story revealed that the birth of a baby is one of the most dramatic and emotional events in human experience. Jay was present throughout Yolanda’s labor and delivery. Yolanda explained:

·  By morning, we knew I was in labor. It was Thursday, so we went in for my usual weekly appointment. The doctor said, yes, the baby was on the way, but it would be a while. He told us to go home and relax and come to the hospital in three or four hours. We checked in at 3 in the afternoon; Joshua arrived at 2 o’clock the next morning. When, finally, I was ready to deliver, it went quickly; a half hour or so and some good hard pushes, and there he was! His face was red and puffy, and his head was misshapen, but I thought, “Our son! I can’t believe he’s really here.”

Jay was also elated by Joshua’s birth. “I wanted to support Yolanda and to experience as much as I could. It was awesome, indescribable,” he said, holding Joshua over his shoulder and patting and kissing him gently. In the following sections, we explore the experience of childbirth, from both the parents’ and the baby’s point of view.

The stages of Childbirth

It is not surprising that childbirth is often referred to as labor. It is the hardest physical work a woman may ever do. A complex series of hormonal changes between mother and fetus initiates the process, which naturally divides into three stages (see  Figure 3.4 ):

· 1. Dilation and effacement of the cervix. This is the longest stage of labor, lasting an average of 12 to 14 hours with a first birth and 4 to 6 hours with later births. Contractions of the uterus gradually become more frequent and powerful, causing the cervix, or uterine opening, to widen and thin to nothing, forming a clear channel from the uterus into the birth canal, or vagina.

· 2. Delivery of the baby. This stage is much shorter, lasting about 50 minutes for a first birth and 20 minutes in later births. Strong contractions of the uterus continue, but the mother also feels a natural urge to squeeze and push with her abdominal muscles. As she does so with each contraction, she forces the baby down and out.

· 3. Delivery of the placenta. Labor comes to an end with a few final contractions and pushes. These cause the placenta to separate from the wall of the uterus and be delivered in about 5 to 10 minutes.

FIGURE 3.4 The three stages of labor.

The Baby’s Adaptation to Labor and Delivery

At first glance, labor and delivery seem like a dangerous ordeal for the baby. The strong contractions exposed Joshua’s head to a great deal of pressure, and they squeezed the placenta and the umbilical cord repeatedly. Each time, Joshua’s supply of oxygen was temporarily reduced.

Fortunately, healthy babies are well-equipped to withstand these traumas. The force of the contractions causes the infant to produce high levels of stress hormones. Unlike during pregnancy, when excessive stress endangers the fetus, during childbirth high levels of infant cortisol and other stress hormones are adaptive. They help the baby withstand oxygen deprivation by sending a rich supply of blood to the brain and heart (Gluckman, Sizonenko, & Bassett,  1999 ). In addition, stress hormones prepare the baby to breathe by causing the lungs to absorb any remaining fluid and by expanding the bronchial tubes (passages leading to the lungs). Finally, stress hormones arouse the infant into alertness. Joshua was born wide awake, ready to interact with the surrounding world.

The Newborn Baby’s Appearance

Parents are often surprised at the odd-looking newborn—a far cry from the storybook image they may have had in their minds. The average newborn is 20 inches long and 7½ pounds in weight; boys tend to be slightly longer and heavier than girls. The head is large in comparison to the trunk and legs, which are short and bowed. This combination of a large head (with its well-developed brain) and a small body means that human infants learn quickly in the first few months of life. But, unlike most other mammals, they cannot get around on their own until much later.

To accommodate the well-developed brain, a newborn’s head is large in relation to the trunk and legs. This newborn’s body readily turns pink as she takes her first few breaths.

Even though newborn babies may not match parents’ idealized image, some features do make them attractive (Luo, Li, & Lee,  2011 ). Their round faces, chubby cheeks, large foreheads, and big eyes make adults feel like picking them up and cuddling them.

Assessing the Newborn’s Physical Condition: The Apgar Scale

Infants who have difficulty making the transition to life outside the uterus require special help at once. To assess the newborn’s physical condition quickly, doctors and nurses use the  Apgar Scale . As  Table 3.3 shows, a rating of 0, 1, or 2 on each of five characteristics is made at 1 minute and again at 5 minutes after birth. A combined Apgar score of 7 or better indicates that the infant is in good physical condition. If the score is between 4 and 6, the baby needs assistance in establishing breathing and other vital signs. If the score is 3 or below, the infant is in serious danger and requires emergency medical attention. Two Apgar ratings are given because some babies have trouble adjusting at first but do quite well after a few minutes (Apgar,  1953 ).

image8 Approaches to Childbirth

Childbirth practices, like other aspects of family life, are molded by the society of which mother and baby are a part. In many village and tribal cultures, expectant mothers are well-acquainted with the childbirth process. For example, the Jarara of South America and the Pukapukans of the Pacific Islands treat birth as a vital part of daily life. The Jarara mother gives birth in full view of the entire community, including small children. The Pukapukan girl is so familiar with the events of labor and delivery that she frequently can be seen playing at it. Using a coconut to represent the baby, she stuffs it inside her dress, imitates the mother’s pushing, and lets the nut fall at the proper moment. In most nonindustrialized cultures, women are assisted—though often not by medical personnel—during labor and delivery. Among the Mayans of the Yucatán, the mother leans against the body of a woman called the “head helper,” who supports her weight and breathes with her during each contraction (Jordan,  1993 ; Mead & Newton,  1967 ).

TABLE 3.3 The Apgar scale

  RATING
SIGN  a

0 1 2
Heart rate No heartbeat Under 100 beats per minute 100 to 140 beats per minute
Respiratory effort No breathing for 60 seconds Irregular, shallow breathing Strong breathing and crying
Reflex irritability (sneezing, coughing, and grimacing) No response Weak reflexive response Strong reflexive response
Muscle tone Completely limp Weak movements of arms and legs Strong movements of arms and legs
Color b Blue body, arms, and legs Body pink with blue arms and legs Body, arms, and legs completely pink

a To remember these signs, you may find it helpful to use a technique in which the original labels are reordered and renamed as follows: color = Appearance; heart rate = Pulse; reflex irritability = Grimace; muscle tone = Activity; and respiratory effort = Respiration. Together, the first letters of the new labels spell Apgar.

b The skin tone of nonwhite babies makes it difficult to apply the “pink” color criterion. However, newborns of all races can be rated for pinkish glow resulting from the flow of oxygen through body tissues.

In Western nations, childbirth has changed dramatically over the centuries. Before the late 1800s, birth usually took place at home and was a family-centered event. The industrial revolution brought greater crowding to cities, along with new health problems. As a result, childbirth moved from home to hospital, where the health of mothers and babies could be protected. Once doctors assumed responsibility for childbirth, women’s knowledge of it declined, and relatives and friends no longer participated (Borst,  1995 ).

In this Peruvian health clinic, families are encouraged to incorporate practices of their village culture into the birth experience. Here, a familiar attendant soothes a new mother as her baby is delivered.

By the 1950s and 1960s, women had begun to question the medical procedures that had come to be used routinely during labor and delivery. Many felt that routine use of strong drugs and delivery instruments had robbed them of a precious experience and was often neither necessary nor safe for the baby. Gradually, a natural childbirth movement arose in Europe and spread to North America. Its purpose was to make hospital birth as comfortable and rewarding for mothers as possible. Today, most hospitals offer birth centers that are family-centered and homelike. Freestanding birth centers, which permit greater maternal control over labor and delivery, including choice of delivery positions, presence of family members and friends, and early contact between parents and baby, also exist. And a small number of North American women reject institutional birth entirely and choose to have their babies at home.

Natural, or Prepared, Childbirth

Yolanda and Jay chose  natural , or prepared, childbirth—a group of techniques aimed at reducing pain and medical intervention and making childbirth a rewarding experience. Most natural childbirth programs draw on methods developed by Grantly Dick-Read ( 1959 ) in England and Fernand Lamaze ( 1958 ) in France. These physicians recognized that cultural attitudes had taught women to fear the birth experience. An anxious, frightened woman in labor tenses muscles, turning the mild pain that sometimes accompanies strong contractions into intense pain.

· In a typical natural childbirth program, the expectant mother and a companion (a partner, relative, or friend) participate in three activities:

· ● Classes. Yolanda and Jay attended a series of classes in which they learned about the anatomy and physiology of labor and delivery. Knowledge about the birth process reduces a mother’s fear.

· ● Relaxation and breathing techniques. During each class, Yolanda was taught relaxation and breathing exercises aimed at counteracting the pain of uterine contractions.

· ● Labor coach. Jay learned how to help Yolanda during childbirth by reminding her to relax and breathe, massaging her back, supporting her body, and offering encouragement and affection.

Social support is important to the success of natural childbirth techniques. In Guatemalan and American hospitals that routinely isolated patients during childbirth, some mothers were randomly assigned a doula—a Greek word referring to a trained lay attendant—who stayed with them throughout labor and delivery, talking to them, holding their hands, and rubbing their backs to promote relaxation. These mothers had fewer birth complications, and their labors were several hours shorter than those of women who did not have supportive companionship. Guatemalan mothers who received doula support also interacted more positively with their babies after delivery, talking, smiling, and gently stroking (Kennell et al.,  1991 ; Sosa et al.,  1980 ).

Other studies indicate that mothers who are supported during labor and delivery—either by a lay birth attendant or by a relative or friend with doula training—less often have cesarean (surgical) deliveries or need medication to control pain. Also, their babies’ Apgar scores are higher, and they are more likely to be breastfeeding at a two-month follow-up (Campbell et al.,  2006 ,  2007 ; Hodnett et al.,  2003 ; McGrath & Kennell,  2008 ). Social support also makes Western hospital-birth customs more acceptable to women from parts of the world where assistance from family and community members is the norm (Dundek,  2006 ).

LOOK AND LISTEN

Talk to several mothers about social supports available to them during labor and delivery. From the mothers’ perspectives, how did those supports (or lack of support) affect the birth experience?

Home Delivery

Home birth has always been popular in certain industrialized nations, such as England, the Netherlands, and Sweden. The number of American women choosing to have their babies at home rose during the 1970s and 1980s but remains small, at less than 1 percent (U.S. Department of Health and Human Services,  2011a ). Although some home births are attended by doctors, many more are handled by certified nurse–midwives, who have degrees in nursing and additional training in childbirth management.

After a home birth, the midwife and a lay attendant provide support to the new mother. For healthy women attended by a well-trained doctor or midwife, home birth is as safe as hospital birth.

Is it just as safe to give birth at home as in a hospital? For healthy women who are assisted by a well-trained doctor or midwife, it seems so because complications rarely occur (Fullerton, Navarro, & Young,  2007 ; Wax, Pinette, & Cartin,  2010 ). However, if attendants are not carefully trained and prepared to handle emergencies, the rate of infant death is high (Mehlmadrona & Madrona,  1997 ). When mothers are at risk for any kind of complication, the appropriate place for labor and delivery is the hospital, where life-saving treatment is available.

image9 Medical Interventions

Four-year-old Melinda walks with a halting, lumbering gait and has difficulty keeping her balance. She has cerebral palsy, a general term for a variety of impairments in muscle coordination caused by brain damage before, during, or just after birth. For about 10 percent of these children, including Melinda, brain damage was caused by  anoxia , or inadequate oxygen supply, during labor and delivery (Bracci, Perrone, & Buonocore,  2006 ). Melinda was also in  breech position , turned so that the buttocks or feet would be delivered first, and the umbilical cord was wrapped around her neck. Her mother had gotten pregnant accidentally, was frightened and alone, and arrived at the hospital at the last minute. Had she come to the hospital earlier, doctors could have monitored Melinda’s condition and delivered her surgically as soon as squeezing of the umbilical cord led to distress, thereby reducing the damage or preventing it entirely.

In cases like Melinda’s, medical interventions are clearly justified. But in others, they can interfere with delivery and even pose new risks. In the following sections, we examine some commonly used medical procedures during childbirth.

Fetal Monitoring

Fetal monitors  are electronic instruments that track the baby’s heart rate during labor. An abnormal heartbeat may indicate that the baby is in distress due to anoxia and needs to be delivered immediately. Continuous fetal monitoring, which is required in most U.S. hospitals, is used in over 80 percent of American births (Natale & Dodman,  2003 ). The most popular type of monitor is strapped across the mother’s abdomen throughout labor. A second, more accurate method involves threading a recording device through the cervix and placing it directly under the baby’s scalp.

Fetal monitoring is a safe medical procedure that has saved the lives of many babies in high-risk situations. But in healthy pregnancies, it does not reduce the already low rates of infant brain damage and death (Haws et al.,  2009 ). Furthermore, most infants have some heartbeat irregularities during labor, so critics worry that fetal monitors identify many babies as in danger who, in fact, are not. Monitoring is linked to an increase in the number of cesarean (surgical) deliveries, which we will discuss shortly (Thacker & Stroup,  2003 ). In addition, some women complain that the devices are uncomfortable, prevent them from moving easily, and interfere with the normal course of labor.

Still, fetal monitors will probably continue to be used routinely in the United States, even though they are not necessary in most cases. Doctors fear that they will be sued for malpractice if an infant dies or is born with problems and they cannot show that they did everything possible to protect the baby.

Labor and Delivery Medication

Some form of medication is used in more than 80 percent of U.S. births (Althaus & Wax,  2005 ). Analgesics, drugs used to relieve pain, may be given in mild doses during labor to help a mother relax. Anestheticsare a stronger type of painkiller that blocks sensation. Currently, the most common approach to controlling pain during labor is epidural analgesia, in which a regional pain-relieving drug is delivered continuously through a catheter into a small space in the lower spine. Unlike older spinal block procedures, which numb the entire lower half of the body, epidural analgesia limits pain reduction to the pelvic region. Because the mother retains the capacity to feel the pressure of the contractions and to move her trunk and legs, she is able to push during the second stage of labor.

Although pain-relieving drugs help women cope with childbirth and enable doctors to perform essential medical interventions, they also can cause problems. Epidural analgesia, for example, weakens uterine contractions. As a result, labor is prolonged, and the chances of cesarean (surgical) delivery increase (Nguyen et al.,  2010 ). And because drugs rapidly cross the placenta, exposed newborns tend to have lower Apgar scores, to be sleepy and withdrawn, to suck poorly during feedings, and to be irritable when awake (Caton et al.,  2002 ; Eltzschig, Lieberman, & Camann,  2003 ; Emory, Schlackman, & Fiano,  1996 ). Although no confirmed long-term consequences for development exist, the negative impact of these drugs on the newborn’s adjustment supports the current trend to limit their use.

Cesarean Delivery

A  cesarean delivery  is a surgical birth; the doctor makes an incision in the mother’s abdomen and lifts the baby out of the uterus. Forty years ago, cesarean delivery was rare. Since then, cesarean rates have climbed internationally, reaching 16 percent in Finland, 23 percent in New Zealand, 26 percent in Canada, 30 percent in Australia, and 32 percent in the United States (OECD,  2011b ).

Cesareans have always been warranted by medical emergencies, such as Rh incompatibility, premature separation of the placenta from the uterus, or serious maternal illness or infection (for example, the herpes simplex 2 virus, which can infect the baby during a vaginal delivery). Cesareans are also justified in breech births, in which the baby risks head injury or anoxia (as in Melinda’s case). But the infant’s exact position makes a difference: Certain breech babies fare just as well with a normal delivery as with a cesarean (Giuliani et al.,  2002 ). Sometimes the doctor can gently turn the baby into a head-down position during the early part of labor.

Until recently, many women who have had a cesarean have been offered the option of a vaginal birth in subsequent pregnancies. But new evidence indicates that compared with repeated cesareans, a natural labor after a cesarean is associated with slightly increased rates of rupture of the uterus and infant death (Cahill & Macones,  2007 ). As a result, the rule, “Once a cesarean, always a cesarean,” has made a comeback.

Repeated cesareans, however, do not explain the worldwide rise in cesarean deliveries. Instead, medical control over childbirth is largely responsible. Because many needless cesareans are performed, pregnant women should ask questions about the procedure before choosing a doctor. Although the operation itself is safe, mother and baby require more time for recovery. Anesthetic may have crossed the placenta, making cesarean newborns sleepy and unresponsive and at increased risk for breathing difficulties (McDonagh, Osterweil, & Guise,  2005 ).

image10 Preterm and Low-Birth-Weight Infants

Babies born three weeks or more before the end of a full 38-week pregnancy or who weigh less than 5½ pounds (2,500 grams) have for many years been referred to as “premature.” A wealth of research indicates that premature babies are at risk for many problems. Birth weight is the best available predictor of infant survival and healthy development. Many newborns who weigh less than 3½ pounds (1,500 grams) experience difficulties that are not overcome, an effect that becomes stronger as length of pregnancy and birth weight decrease (see  Figure 3.5  on  page 102 ) (Baron & Rey-Casserly,  2010 ; Bolisetty et al.,  2006 ; Dombrowski, Noonan, & Martin,  2007 ). Brain abnormalities, frequent illness, inattention, overactivity, sensory impairments, poor motor coordination, language delays, low intelligence test scores, deficits in school learning, and emotional and behavior problems are some of the difficulties that persist through childhood and ado lescence and into adulthood (Aarnoudse-Moens, Weiglas-Kuperus, & van Goudoever,  2009 ; Clark et al.,  2008 ; Delobel-Ayoub et al.,  2009 ; Nosarti et al.,  2011 ).

About 1 in 13 American infants is born underweight. Although the problem can strike unexpectedly, it occurs especially often among poverty-stricken women (U.S. Department of Health and Human Services,  2011a ). These mothers, as noted earlier, are more likely to be undernourished and to be exposed to other harmful environmental influences. In addition, they often do not receive adequate prenatal care.

Recall from  Chapter 2  that prematurity is also common in multiple births. About 60 percent of twins and more than 90 percent of triplets are born early and low birth weight (U.S. Department of Health and Human Services,  2011a ). Because space inside the uterus is restricted, multiples gain less weight than singletons in the second half of pregnancy.

FIGURE 3.5 Rates of infant survival and child disabilities by length of pregnancy.

In a follow-up of more than 2,300 babies born between 23 and 28 weeks gestation, the percentage who survived decreased and the percentage who displayed moderate to severe disabilities (assessed during the preschool years) increased with reduced length of pregnancy. Severe disabilities included cerebral palsy (unlikely to ever walk), severely delayed mental development, deafness, and blindness. Moderate disabilities included cerebral palsy (able to walk with assistance), moderately delayed mental development, and hearing impairments partially correctable with a hearing aid.

(Adapted from Bolisetty et al., 2006.)

Preterm versus Small-for-Date Infants

Although low-birth-weight infants face many obstacles to healthy development, most go on to lead normal lives; about half of those born at 23 to 24 weeks gestation and weighing only a couple of pounds at birth have no disability (refer again to  Figure 3.5 ). To better understand why some babies do better than others, researchers divide them into two groups.  Preterm infants  are those born several weeks or more before their due date. Although they are small, their weight may still be appropriate, based on time spent in the uterus.  Small-for-date infants  are below their expected weight considering length of the pregnancy. Some small-for-date infants are actually full-term. Others are preterm infants who are especially underweight.

Of the two types of babies, small-for-date infants usually have more serious problems. During the first year, they are more likely to die, catch infections, and show evidence of brain damage. By middle childhood, they are smaller in stature, have lower intelligence test scores, are less attentive, achieve more poorly in school, and are socially immature (Hediger et al.,  2002 ; O’Keefe et al.,  2003 ; Sullivan et al.,  2008 ). Small-for-date infants probably experienced inadequate nutrition before birth. Perhaps their mothers did not eat properly, the placenta did not function normally, or the babies themselves had defects that prevented them from growing as they should. Consequently, small-for-date infants are especially likely to suffer from prenatal neurological impairments that permanently weaken their capacity to manage stress (Wust et al.,  2005 ).

Even among preterm newborns whose weight is appropriate for length of pregnancy, just seven more days—from 34 to 35 weeks—greatly reduces rates of illness, costly medical procedures, and lengthy hospital stays (Gladstone & Katz,  2004 ). And despite being relatively low-risk for disabilities, a substantial number of 34-week preterms are below average in physical growth and mildly to moderately delayed in cognitive development in early and middle childhood (Morse et al.,  2009 ; Pietz et al.,  2004 ; Stephens & Vohr,  2009 ). And in an investigation of over 120,000 New York City births, babies born even 1 or 2 weeks early showed slightly lower reading and math scores at a third-grade follow-up than children who experienced a full-length prenatal period (Noble et al.,  2012 ). These outcomes persisted even after controlling for other factors linked to achievement, such as birth weight and SES. Yet doctors often induce births several weeks preterm, under the misconception that these babies are developmentally “mature.”

Consequences for Caregiving

Imagine a scrawny, thin-skinned infant whose body is only a little larger than the size of your hand. You try to play with the baby by stroking and talking softly, but he is sleepy and unresponsive. When you feed him, he sucks poorly. During the short, unpredictable periods in which he is awake, he is usually irritable.

The appearance and behavior of preterm babies can lead parents to be less sensitive in caring for them. Compared with full-term infants, preterm babies—especially those who are very ill at birth—are less often held close, touched, and talked to gently. At times, mothers of these infants resort to interfering pokes and verbal commands in an effort to obtain a higher level of response from the baby (Barratt, Roach, & Leavitt,  1996 ; Feldman,  2007 ). This may explain why preterm babies as a group are at risk for child abuse.

Research reveals that distressed, emotionally reactive preterm infants are especially susceptible to the effects of parenting quality: Among a sample of preterm 9-month-olds, the combination of infant negativity and angry or intrusive parenting yielded the highest rates of behavior problems at 2 years of age. But with warm, sensitive parenting, distressed preterm babies’ rates of behavior problems were the lowest (Poehlmann et al.,  2011 ). When they are born to isolated, poverty-stricken mothers who cannot provide good nutrition, health care, and parenting, the likelihood of unfavorable outcomes increases. In contrast, parents with stable life circumstances and social supports usually can overcome the stresses of caring for a preterm infant (Ment et al., 2003). In these cases, even sick preterm babies have a good chance of catching up in development by middle childhood.

These findings suggest that how well preterm infants develop has a great deal to do with the parent–child relationship. Consequently, interventions directed at supporting both sides of this tie are more likely to help these infants recover.

Interventions for Preterm Infants

A preterm baby is cared for in a special Plexiglas-enclosed bed called an isolette. Temperature is carefully controlled because these babies cannot yet regulate their own body temperature effectively. To help protect the baby from infection, air is filtered before it enters the isolette. When a preterm infant is fed through a stomach tube, breathes with the aid of a respirator, and receives medication through an intravenous needle, the isolette can be very isolating indeed! Physical needs that otherwise would lead to close contact and other human stimulation are met mechanically.

Special Infant Stimulation.

In proper doses, certain kinds of stimulation can help preterm infants develop. In some intensive care nurseries, preterm babies can be seen rocking in suspended hammocks or lying on waterbeds designed to replace the gentle motion they would have received while still in the mother’s uterus. Other forms of stimulation have also been used—an attractive mobile or a tape recording of a heartbeat, soft music, or the mother’s voice. These experiences promote faster weight gain, more predictable sleep patterns, and greater alertness (Arnon et al.,  2006 ; Marshall-Baker, Lickliter, & Cooper,  1998 ).

Touch is an especially important form of stimulation. In baby animals, touching the skin releases certain brain chemicals that support physical growth—effects believed to occur in humans as well. When preterm infants were massaged several times each day in the hospital, they gained weight faster and, at the end of the first year, were advanced in mental and motor development over preterm babies not given this stimulation (Field,  2001 ; Field, Hernandez-Reif, & Freedman,  2004 ).

In developing countries where hospitalization is not always possible, skin-to-skin “kangaroo care” is the most readily available intervention for promoting the survival and recovery of preterm babies. It involves placing the infant in a vertical position between the mother’s breasts or next to the father’s chest (under the parent’s clothing) so the parent’s body functions as a human incubator. Kangaroo care offers fathers a unique opportunity to increase their involvement in caring for the preterm newborn. Because of its many physical and psychological benefits, the technique is often used in Western nations as a supplement to hospital intensive care.

Kangaroo skin-to-skin contact fosters improved oxygenation of the baby’s body, temperature regulation, sleep, breastfeeding, alertness, and infant survival (Conde-Agudelo, Belizan, & Diaz-Rossello,  2011 ; Lawn et al.,  2010 ). In addition, the kangaroo position provides the baby with gentle stimulation of all sensory modalities: hearing (through the parent’s voice), smell (through proximity to the parent’s body), touch (through skin-to-skin contact), and visual (through the upright position). Mothers and fathers practicing kangaroo care feel more confident about caring for their fragile babies and interact more sensitively and affectionately with them (Dodd,  2005 ; Feldman,  2007 ).

Together, these factors may explain why preterm babies given many hours of kangaroo care in their early weeks, compared to those given little or no such care, score higher on measures of mental and motor development during the first year (Charpak, Ruiz-Peláez, & Figueroa,  2005 ; Feldman,  2007 ). Because of its diverse benefits, more than 80 percent of U.S. hospitals now offer kangaroo care to preterm newborns (Field et al.,  2006 ).

Training Parents in Infant Caregiving Skills.

Interventions that support parents of preterm infants generally teach them about the infant’s characteristics and promote caregiving skills. For parents with adequate economic and personal resources to care for a preterm infant, just a few sessions of coaching in recognizing and responding to the baby’s needs are linked to enhanced parent–infant interaction, reduced infant crying and improved sleep, more rapid language development in the second year, and steady gains in mental test scores that equal those of full-term children by middle childhood (Achenbach et al.,  1990 ; Newnham, Milgrom, & Skouteris,  2009 ).

When preterm infants live in stressed, low-income households, long-term, intensive intervention is required to reduce developmental problems. In the Infant Health and Development Project, preterm babies born into poverty received a comprehensive intervention that combined medical follow-up, weekly parent training sessions, and cognitively stimulating child care from 1 to 3 years of age. More than four times as many intervention children as controls (39 versus 9 percent) were within normal range at age 3 in intelligence, psychological adjustment, and physical growth (Bradley et al.,  1994 ). In addition, mothers in the intervention group were more affectionate and more often encouraged play and cognitive mastery in their children—one reason their 3-year-olds may have been developing so favorably (McCarton,  1998 ).

Social Issues: Health A Cross-National Perspective on Health Care and Other Policies for Parents and Newborn Babies

Infant mortality —the number of deaths in the first year of life per 1,000 live births—is an index used around the world to assess the overall health of a nation’s children. Although the United States has the most up-to-date health-care technology in the world, it has made less progress in reducing infant deaths than many other countries. Over the past three decades, it has slipped in the international rankings, from seventh in the 1950s to twenty-eighth in 2012. Members of America’s poor ethnic minorities are at greatest risk. African-American and Native-American babies are nearly twice as likely as white infants to die in the first year of life (U.S. Census Bureau,  2012a ,  2012b ).

Neonatal mortality, the rate of death within the first month of life, accounts for 67 percent of the infant death rate in the United States. Two factors are largely responsible for neonatal mortality. The first is serious physical defects, most of which cannot be prevented. The percentage of babies born with physical defects is about the same in all ethnic and income groups. The second leading cause of neonatal mortality is low birth weight, which is largely preventable. African-American and Native-American babies are twice as likely as white infants to be born early and underweight (U.S. Census Bureau,  2012b ).

Widespread poverty and weak health-care programs for mothers and young children are largely responsible for these trends. Each country in  Figure 3.6  that outranks the United States in infant survival provides all its citizens with government-sponsored health-care benefits. And each takes extra steps to make sure that pregnant mothers and babies have access to good nutrition, high-quality medical care, and social and economic supports that promote effective parenting.

For example, all Western European nations guarantee women a certain number of prenatal visits at very low or no cost. After a baby is born, a health professional routinely visits the home to provide counseling about infant care and to arrange continuing medical services. Home assistance is especially extensive in the Netherlands. For a token fee, each mother is granted a specially trained maternity helper, who assists with infant care, shopping, housekeeping, meal preparation, and the care of other children during the days after delivery (Zwart,  2007 ).

These fathers in Stockholm take advantage of Sweden’s parental leave program, the most generous in the world, which provides them with two weeks of birth leave followed by 16 months of paid leave at 80 percent of prior earnings.

Paid, job-protected employment leave is another vital societal intervention for new parents. Canadian mothers are eligible for 15 weeks’ maternity leave at 55 percent of prior earnings (up to a maximum of $485 per week), and Canadian mothers or fathers can take an additional 35 weeks of parental leave at the same rate. Paid leave is widely available in other industrialized nations as well. Sweden has the most generous parental leave program in the world. Mothers can begin maternity leave 60 days prior to expected delivery, extending it to six weeks after birth; fathers are granted two weeks of birth leave. In addition, either parent can take full leave for 16 months at 80 percent of prior earnings, followed by an additional three months at a modest flat rate. Each parent is also entitled to another 18 months of unpaid leave. Furthermore, many countries supplement basic paid leave. In Germany, for example, after a fully paid three-month leave, a parent may take one more year at a flat rate and three additional years at no pay (OECD,  2006 ; Waldfogel,  2001 ).

Yet in the United States, the federal government mandates only 12 weeks of unpaid leave for employees in businesses with at least 50 workers. Most women, however, work in smaller businesses, and many of those who work in large enough companies cannot afford to take unpaid leave (Hewlett,  2003 ). Similarly, though paternal leave predicts fathers’ increased involvement in infant care at the end of the first year, many fathers take little or none at all (Nepomnyaschy & Waldfogel,  2007 ; OECD,  2006 ). In 2002, California became the first state to guarantee a mother or father paid leave—up to six weeks at half salary, regardless of the size of the company. Since then, Hawaii, New Jersey, New York, Rhode Island, and the territory of Puerto Rico have passed similar legislation.

Nevertheless, six weeks of childbirth leave (the norm in the United States) is not enough. When a family is stressed by a baby’s arrival, leaves of six weeks or less are linked to increased maternal anxiety, depression, marital dissatisfaction, sense of role overload (conflict between work and family responsibilities), and negative interactions with the baby. A longer leave (12 weeks or more) predicts favorable maternal mental health, supportive marital interaction, and sensitive caregiving (Feldman, Sussman, & Zigler,  2004 ; Hyde et al.,  2001 ). Single women and their babies are most hurt by the absence of a generous national paid-leave policy. These mothers, who are usually the sole source of support for their families, can least afford to take time from their jobs.

FIGURE 3.6 Infant mortality in thirty nations.

Despite its advanced health-care technology, the United States ranks poorly. It is twenty-eighth in the world, with a death rate of 6.1 infants per 1,000 births.

(Adapted from U.S. Census Bureau, 2012a.)

In countries with low infant mortality rates, expectant parents need not wonder how or where they will get health care and other resources to support their baby’s development. The powerful impact of universal, high-quality health care, generous parental leave, and other social services on maternal and infant well-being provides strong justification for these policies.

At ages 5 and 8, children who had attended the child-care program regularly—for more than 350 days over the three-year period—continued to show better intellectual functioning. The more they attended, the higher they scored, with greater gains among those whose birth weights were higher—between 4½ and 5½ pounds (2,001 to 2,500 grams). In contrast, children who attended only sporadically gained little or even lost ground (Hill, Brooks-Gunn, & Waldfogel,  2003 ). These findings confirm that babies who are both preterm and economically disadvantaged require intensive intervention. And special strategies, such as extra adult–child interaction, may be necessary to achieve lasting changes in children with the lowest birth weights.

Nevertheless, even the best caregiving environments cannot “fix” the enormous biological risks associated with extremely low birth weight. A better course of action would be to prevent this serious threat to infant survival and development. The high rate of underweight babies in the United States—one of the worst in the industrialized world—could be greatly reduced by improving the health and social conditions described in the  Social Issues: Health  box above.

image11 Birth Complications, Parenting, and Resilience

In the preceding sections, we considered a variety of birth complications. Now let’s try to put the evidence together. Can any general principles help us understand how infants who survive a traumatic birth are likely to develop? A landmark study carried out in Hawaii provides some answers.

In 1955, Emmy Werner and Ruth Smith began to follow nearly 700 infants on the island of Kauai who had experienced mild, moderate, or severe birth complications. Each was matched, on the basis of SES and ethnicity, with a healthy newborn (Werner & Smith,  1982 ). Findings showed that the likelihood of long-term difficulties increased if birth trauma was severe. But among mildly to moderately stressed children, those growing up in stable families did almost as well on measures of intelligence and psychological adjustment as those with no birth problems. Children exposed to poverty, family disorganization, and mentally ill parents often developed serious learning difficulties, behavior problems, and emotional disturbance.

The Kauai study tells us that as long as birth injuries are not overwhelming, a supportive home environment can restore children’s growth. But the most intriguing cases in this study were the handful of exceptions. A few children with both fairly serious birth complications and troubled family environments grew into competent adults who fared as well as controls in career attainment and psychological adjustment. Werner and Smith found that these children relied on factors outside the family and within themselves to overcome stress. Some had attractive personalities that drew positive responses from relatives, neighbors, and peers. In other instances, a grandparent, aunt, uncle, or babysitter provided the needed emotional support (Werner,  1989 ,  2001 ; Werner & Smith,  1992 ).

Do these outcomes remind you of the characteristics of resilient children, discussed in  Chapter 1 ? The Kauai study and other similar investigations reveal that the impact of early biological risks often wanes as children’s personal characteristics and social experiences contribute increasingly to their functioning (Laucht, Esser, & Schmidt,  1997 ; Resnick et al.,  1999 ). In sum, when the overall balance of life events tips toward the favorable side, children with serious birth problems can develop successfully.

image12 The Newborn Baby’s Capacities

Newborn infants have a remarkable set of capacities that are crucial for survival and for evoking attention and care from parents. In relating to the physical and social world, babies are active from the very start.

Reflexes

A  reflex  is an inborn, automatic response to a particular form of stimulation. Reflexes are the newborn baby’s most obvious organized patterns of behavior. As Jay placed Joshua on a table in my classroom, we saw several. When Jay bumped the side of the table, Joshua reacted by flinging his arms wide and bringing them back toward his body. As Yolanda stroked Joshua’s cheek, he turned his head in her direction.  TAKE A MOMENT…  Look at  Table 3.4  and see if you can name the newborn reflexes that Joshua displayed.

Some reflexes have survival value. The rooting reflex helps a breastfed baby find the mother’s nipple. Babies display it only when hungry and touched by another person, not when they touch themselves (Rochat & Hespos,  1997 ). At birth, babies adjust their sucking pressure to how easily milk flows from the nipple (Craig & Lee,  1999 ). And if sucking were not automatic, our species would be unlikely to survive for a single generation!

In the Moro reflex, loss of support or a sudden loud sound causes the baby to extend the legs and throw the arms outward in an “embracing” motion.

A few reflexes form the basis for complex motor skills that will develop later. The stepping reflex looks like a primitive walking response. Unlike other reflexes, it appears in a wide range of situations—with the newborn’s body in a sideways or upside-down position, with feet touching walls or ceilings, and even with legs dangling in the air (Adolph & Berger,  2006 ). One reason that babies frequently engage in the alternating leg movements of stepping is their ease compared with other movement patterns; repetitive movement of just one leg or of both legs at once requires more effort.

TABLE 3.4 Some Newborn Reflexes

REFLEX STIMULATION RESPONSE AGE OF DISAPPEARANCE FUNCTION
Eye blink Shine bright light at eyes or clap hand near head. Infant quickly closes eyelids. Permanent Protects infant from strong stimulation
Rooting Stroke cheek near corner of mouth. Head turns toward source of stimulation. 3 weeks (becomes voluntary turning at this time) Helps infant find the nipple
Sucking Place finger in infant’s mouth. Infant sucks finger rhythmically. Replaced by voluntary sucking after 4 months Permits feeding
Moro Hold infant horizontally on back and let head drop slightly, or produce a sudden loud sound against surface supporting infant. Infant makes an “embracing” motion by arching back, extending legs, throwing arms outward, and then bringing arms in toward the body. 6 months In human evolutionary past, may have helped infant cling to mother
Palmar grasp Place finger in infant’s hand and press against palm. Infant spontaneously grasps finger. 3–4 months Prepares infant for voluntary grasping
Tonic neck Turn head to one side while infant is lying awake on back. Infant lies in a “fencing position.” One arm is extended in front of eyes on side to which head is turned, other arm is flexed. 4 months May prepare infant for voluntary reaching
Stepping Hold infant under arms and permit bare feet to touch a flat surface. Infant lifts one foot after another in stepping response. 2 months in infants who gain weight quickly; sustained in lighter infants Prepares infant for voluntary walking
Babinski Stroke sole of foot from toe toward heel. Toes fan out and curl as foot twists in. 8–12 months Unknown

Sources: Knobloch & Pasamanick, 1974; Prechtl & Beintema, 1965; Thelen, Fisher, & Ridley-Johnson, 1984.

In infants who gain weight quickly in the weeks after birth, the stepping reflex drops out because thigh and calf muscles are not strong enough to lift the baby’s chubby legs. But if the lower part of the infant’s body is dipped in water, the reflex reappears because the buoyancy of the water lightens the load on the baby’s muscles (Thelen, Fisher, & Ridley-Johnson,  1984 ). When stepping is exercised regularly, babies make more reflexive stepping movements and are likely to walk several weeks earlier than if stepping is not practiced (Zelazo et al.,  1993 ). However, there is no special need for infants to practice the stepping reflex because all normal babies walk in due time.

Several reflexes help parents and infants establish gratifying interaction. A baby who searches for and successfully finds the nipple, sucks easily during feedings, and grasps when the hand is touched encourages parents to respond lovingly and feel competent as caregivers. Reflexes can also help caregivers comfort the baby because they permit infants to control distress and amount of stimulation. For example, on short trips with Joshua to the grocery store, Yolanda brought along a pacifier. If he became fussy, sucking helped quiet him until she could feed, change, or hold him.

When held upright under the arms, newborns show a reflexive stepping response, which forms the basis for later walking.

The palmar grasp reflex is so strong during the first week after birth that many infants can use it to support their entire weight.

Refer to  Table 3.4  again, and you will see that most newborn reflexes disappear during the first six months. Researchers believe that this is due to a gradual increase in voluntary control over behavior as the cerebral cortex develops. Pediatricians test reflexes carefully because reflexes can reveal the health of the baby’s nervous system. Weak or absent reflexes, overly rigid or exaggerated reflexes, and reflexes that persist beyond the point in development when they should normally disappear can signal brain damage (Schott & Rossor,  2003 ; Zafeiriou,  2000 ).

States

Throughout the day and night, newborn infants move in and out of five  states of arousal , or degrees of sleep and wakefulness, described in  Table 3.5 . During the first month, these states alternate frequently. The most fleeting is quiet alertness, which usually moves quickly toward fussing and crying. Much to the relief of their fatigued parents, newborns spend the greatest amount of time asleep—about 16 to 18 hours a day. Because the fetus tends to synchronize periods of rest and activity with those of the mother, newborns sleep more at night than during the day (Heraghty et al.,  2008 ). Nevertheless, young babies’ sleep–wake cycles are affected more by fullness–hunger than by darkness–light (Davis, Parker, & Montgomery,  2004 ).

However, striking individual differences in daily rhythms exist that affect parents’ attitudes toward and interactions with the baby. A few newborns sleep for long periods, increasing the energy their well-rested parents have for sensitive, responsive care. Other babies cry a great deal, and their parents must exert great effort to soothe them. If these parents do not succeed, they may feel less competent and less positive toward their infant.

Furthermore, from birth on, arousal patterns have implications for cognitive development. Babies who spend more time alert probably receive more social stimulation and opportunities to explore and, therefore, may have a slight advantage in mental development (Sadeh et al.,  2007 ; Smart & Hiscock,  2007 ). And as with adults, sleep enhances babies’ learning and memory. In one study, eye-blink responses and brain-wave recordings revealed that sleeping newborns readily learned that a tone would be followed by a puff of air to the eye (Fifer et al.,  2010 ). Because young infants spend so much time sleeping, the capacity to learn about external stimuli during sleep may be essential for adaptation to their surroundings.

Of the states listed in  Table 3.5 , the two extremes—sleep and crying—have been of greatest interest to researchers. Each tells us something about normal and abnormal early development.

Sleep.

Observing Joshua as he slept, Yolanda and Jay wondered why his eyelids and body twitched and his rate of breathing varied. Sleep is made up of at least two states. During irregular, or  rapid-eye-movement (REM), sleep , brain-wave activity is remarkably similar to that of the waking state. The eyes dart beneath the lids; heart rate, blood pressure, and breathing are uneven; and slight body movements occur. In contrast, during regular, or  non-rapid-eye-movement (NREM), sleep , the body is almost motionless, and heart rate, breathing, and brain-wave activity are slow and even.

Like children and adults, newborns alternate between REM and NREM sleep. However, they spend far more time in the REM state than they ever will again. REM sleep accounts for 50 percent of a newborn baby’s sleep time. By 3 to 5 years, it has declined to an adultlike level of 20 percent (Louis et al.,  1997 ).

TABLE 3.5 Infant states of Arousal

STATE DESCRIPTION DAILY DURATION IN NEWBORN
Regular, or NREM, sleep The infant is at full rest and shows little or no body activity. The eyelids are closed, no eye movements occur, the face is relaxed, and breathing is slow and regular. 8–9 hours
Irregular, or REM, sleep Gentle limb movements, occasional stirring, and facial grimacing occur. Although the eyelids are closed, occasional rapid eye movements can be seen beneath them. Breathing is irregular. 8–9 hours
Drowsiness The infant is either falling asleep or waking up. Body is less active than in irregular sleep but more active than in regular sleep. The eyes open and close; when open, they have a glazed look. Breathing is even but somewhat faster than in regular sleep. Varies
Quiet alertness The infant’s body is relatively inactive, with eyes open and attentive. Breathing is even. 2–3 hours
Waking activity and crying The infant shows frequent bursts of uncoordinated body activity. Breathing is very irregular. Face may be relaxed or tense and wrinkled. Crying may occur. 1–4 hours

Why do young infants spend so much time in REM sleep? In older children and adults, the REM state is associated with dreaming. Babies probably do not dream, at least not in the same way we do. But researchers believe that the stimulation of REM sleep is vital for growth of the central nervous system. Young infants seem to have a special need for this stimulation because they spend little time in an alert state, when they can get input from the environment. In support of this idea, the percentage of REM sleep is especially great in the fetus and in preterm babies, who are even less able than full-term newborns to take advantage of external stimulation (de Weerd & van den Bossche,  2003 ; Peirano, Algarin, & Uauy,  2003 ).

Because newborns’ normal sleep behavior is organized and patterned, observations of sleep states can help identify central nervous system abnormalities. In infants who are brain-damaged or who have experienced birth trauma, disturbed REM–NREM sleep cycles are often present. Babies with poor sleep organization are likely to be behaviorally disorganized and, therefore, to have difficulty learning and evoking caregiver interactions that enhance their development. In the preschool years, they show delayed motor, cognitive, and language development (de Weerd & van den Bossche,  2003 ; Feldman,  2006 ; Holditch-Davis, Belyea, & Edwards,  2005 ). And the brain-functioning problems that underlie newborn sleep irregularities may culminate in sudden infant death syndrome, a major cause of infant mortality (see the  Biology and Environment  box on  page 110 ).

Crying.

Crying is the first way that babies communicate, letting parents know they need food, comfort, or stimulation. During the weeks after birth, all infants have some fussy periods when they are difficult to console. But most of the time, the nature of the cry, combined with the experiences leading up to it, helps guide parents toward its cause. The baby’s cry is a complex stimulus that varies in intensity, from a whimper to a message of all-out distress (Gustafson, Wood, & Green,  2000 ; Wood,  2009 ). As early as the first few weeks, infants can be identified by the unique vocal “signature” of their cries, which helps parents locate their baby from a distance (Gustafson, Green, & Cleland,  1994 ).

Young infants usually cry because of physical needs. Hunger is the most common cause, but babies may also cry in response to temperature change when undressed, a sudden noise, or a painful stimulus. Newborns (as well as older babies) often cry at the sound of another crying baby (Dondi, Simion, & Caltran,  1999 ; Geangu et al.,  2010 ). Some researchers believe that this response reflects an inborn capacity to react to the suffering of others. Furthermore, crying typically increases during the early weeks, peaks at about 6 weeks, and then declines (Barr,  2001 ). Because this trend appears in many cultures with vastly different infant care practices, researchers believe that normal readjustments of the central nervous system underlie it.  TAKE A MOMENT…  The next time you hear an infant cry, notice your own reaction. The sound stimulates strong feelings of arousal and discomfort in men and women, parents and nonparents alike (Murray,  1985 ). This powerful response is probably innately programmed in humans to make sure that babies receive the care and protection they need to survive.

Soothing Crying Infants.

Although parents do not always interpret their baby’s cry correctly, their accuracy improves with experience. At the same time, they vary widely in responsiveness. Parents who are high in empathy (ability to take the perspective of others in distress) and who hold “child-centered” attitudes toward infant care (for example, believe that babies cannot be spoiled by being picked up) are more likely to respond quickly and sensitively to a crying baby (Leerkes,  2010 ; Zeifman,  2003 ).

To soothe his crying infant, this father rocks her gently while talking softly.

Fortunately, there are many ways to soothe a crying baby when feeding and diaper changing do not work (see Applying What We Know on  page 111 ). The technique that Western parents usually try first, lifting the baby to the shoulder and rocking or walking, is highly effective. Another common soothing method is swaddling—wrapping the baby snugly in a blanket. The Quechua, who live in the cold, high-altitude desert regions of Peru, dress young babies in layers of clothing and blankets that cover the head and body, a practice that reduces crying and promotes sleep (Tronick, Thomas, & Daltabuit,  1994 ). It also allows the baby to conserve energy for early growth in the harsh Peruvian highlands.

In a public setting, watch several parents soothe their crying babies. What techniques did the parents use, and how successful were they?

Biology and Environment The Mysterious Tragedy of Sudden Infant Death Syndrome

Millie awoke with a start one morning and looked at the clock. It was 7:30, and Sasha had missed both her night waking and her early morning feeding. Wondering if she was all right, Millie and her husband Stuart tiptoed into the room. Sasha lay still, curled up under her blanket. She had died silently during her sleep.

Sasha was a victim of  sudden infant death syndrome (SIDS) , the unexpected death, usually during the night, of an infant under 1 year of age that remains unexplained after thorough investigation. In industrialized nations, SIDS is the leading cause of infant mortality between 1 and 12 months, accounting for about 20 percent of these deaths in the United States (Mathews & MacDorman,  2008 ).

SIDS victims usually show physical problems from the beginning. Early medical records of SIDS babies reveal higher rates of prematurity and low birth weight, poor Apgar scores, and limp muscle tone. Abnormal heart rate and respiration and disturbances in sleep–wake activity and in REM–NREM cycles while asleep are also involved (Cornwell & Feigenbaum,  2006 ; Kato et al.,  2003 ). At the time of death, many SIDS babies have a mild respiratory infection (Blood-Siegfried,  2009 ). This seems to increase the chances of respiratory failure in an already vulnerable baby.

Mounting evidence suggests that impaired brain functioning is a major contributor to SIDS. Between 2 and 4 months, when SIDS is most likely to occur, reflexes decline and are replaced by voluntary, learned responses. Neurological weaknesses may prevent SIDS babies from acquiring behaviors that replace defensive reflexes (Lipsitt,  2003 ). As a result, when breathing difficulties occur during sleep, infants do not wake up, shift their position, or cry out for help. Instead, they simply give in to oxygen deprivation and death. In support of this interpretation, autopsies reveal that the brains of SIDS babies contain unusually low levels of serotonin (a brain chemical that assists with arousal when survival is threatened) as well as other abnormalities in centers that control breathing and arousal (Duncan et al.,  2010 ).

Several environmental factors are linked to SIDS. Maternal cigarette smoking, both during and after pregnancy, as well as smoking by other caregivers, doubles risk of the disorder. Babies exposed to cigarette smoke arouse less easily from sleep and have more respiratory infections (Richardson, Walker, & Horne,  2009 ; Shah, Sullivan, & Carter,  2006 ). Prenatal abuse of drugs that depress central nervous system functioning (alcohol, opiates, and barbiturates) increases the risk of SIDS as much as fifteenfold (Hunt & Hauck,  2006 ). Babies of drug-abusing mothers are especially likely to display SIDS-related brain abnormalities (Kinney,  2009 ).

SIDS babies are also more likely to sleep on their stomachs than on their backs and often are wrapped very warmly in clothing and blankets. Infants who sleep on their stomachs less often wake when their breathing is disturbed (Richardson, Walker, & Horne,  2008 ). In other cases, healthy babies sleeping face down on soft bedding may die from continually breathing their own exhaled breath.

Quitting smoking and drug taking, changing an infant’s sleeping position, and removing a few bedclothes can reduce the incidence of SIDS. For example, if women refrained from smoking while pregnant, an estimated 30 percent of SIDS cases would be prevented. Public education campaigns that encourage parents to put their infants down on their backs have cut the incidence of SIDS in half in many Western nations (Moon, Horne, & Hauck,  2007 ). Another protective measure is pacifier use: Sleeping babies who suck arouse more easily in response to breathing and heart-rate irregularities (Li et al.,  2006 ). Nevertheless, compared with white infants, SIDS rates are two to six times as high in poverty-stricken minority groups, where parental stress, substance abuse, reduced access to health care, and lack of knowledge about safe sleep practices are widespread (Colson et al.,  2009 ; Pickett, Luo, & Lauderdale,  2005 ).

Public education campaigns encouraging parents to put their infants down on their backs to sleep have helped reduce the incidence of SIDS by more than half in many Western nations.

When SIDS does occur, surviving family members require a great deal of help to overcome a sudden and unexpected death. As Millie commented six months after Sasha’s death, “It’s the worst crisis we’ve ever been through. What’s helped us most are the comforting words of others who’ve experienced the same tragedy.”

Applying What We Know Soothing a Crying Baby

Method Explanation
Talk softly or play rhythmic sounds. Continuous, monotonous, rhythmic sounds (such as a clock ticking, a fan whirring, or peaceful music) are more effective than intermittent sounds.
Offer a pacifier. Sucking helps babies control their own level of arousal.
Massage the baby’s body. Stroking the baby’s torso and limbs with continuous, gentle motions relaxes the baby’s muscles.
Swaddle the baby. Restricting movement and increasing warmth often soothe a young infant.
Lift the baby to the shoulder and rock or walk. This combination of physical contact, upright posture, and motion is an effective soothing technique, causing young infants to become quietly alert.
Take the baby for a short car ride or a walk in a baby carriage; swing the baby in a cradle. Gentle, rhythmic motion of any kind helps lull the baby to sleep.
Combine several of the methods just listed. Stimulating several of the baby’s senses at once is often more effective than stimulating only one.
If these methods do not work, let the baby cry for a short period. Occasionally, a baby responds well to just being put down and, after a few minutes, will fall asleep.

In many tribal and village societies and non-Western developed nations (such as Japan), babies are in physical contact with their caregivers almost continuously. Infants in these cultures show shorter bouts of crying than their American counterparts (Barr,  2001 ). When Western parents choose to practice “proximal care” by holding their babies extensively, amount of crying in the early months is reduced by about one-third (St James-Roberts et al.,  2006 ).

Like the Quechua of Peru, the Mongol people of Central Asia heavily swaddle their babies, a practice that reduces crying and promotes sleep while also protecting infants from the region’s harsh winters.

But not all research indicates that rapid parental responsiveness reduces infant crying (van IJzendoorn & Hubbard,  2000 ). Parents must make reasoned choices about what to do on the basis of culturally accepted practices, the suspected reason for the cry, and the context in which it occurs—for example, in the privacy of their own home or while having dinner at a restaurant. Fortunately, with age, crying declines. Virtually all researchers agree that parents can lessen older babies’ need to cry by encouraging more mature ways of expressing their desires, such as gestures and vocalizations.

Abnormal Crying.

Like reflexes and sleep patterns, the infant’s cry offers a clue to central nervous system distress. The cries of brain-damaged babies and those who have experienced prenatal and birth complications are often shrill, piercing, and shorter in duration than those of healthy infants (Boukydis & Lester,  1998 ; Green, Irwin, & Gustafson,  2000 ). Even newborns with a fairly common problem—colic, or persistent crying—tend to have high-pitched, harsh-sounding cries (Zeskind & Barr,  1997 ). Although the cause of colic is unknown, certain newborns, who react especially strongly to unpleasant stimuli, are susceptible. Because their crying is intense, they find it harder to calm down than other babies (Barr et al.,  2005 ; St James-Roberts et al.,  2003 ). Colic generally subsides between 3 and 6 months.

Most parents try to respond to a crying baby with extra care and attention, but sometimes the cry is so unpleasant and the infant so difficult to soothe that parents become frustrated, resentful, and angry. Preterm and ill babies are more likely to be abused by highly stressed parents, who sometimes mention a high-pitched, grating cry as one factor that caused them to lose control and harm the baby (St James-Roberts,  2007 ). We will discuss a host of additional influences on child abuse in  Chapter 8 .

Sensory Capacities

On his visit to my class, Joshua looked wide-eyed at my bright pink blouse and turned to the sound of his mother’s voice. During feedings, he lets Yolanda know through his sucking rhythm that he prefers the taste of breast milk to plain water. Clearly, Joshua has some well-developed sensory capacities. In the following sections, we explore the newborn’s responsiveness to touch, taste, smell, sound, and visual stimulation.

Touch.

In our discussion of preterm infants, we saw that touch helps stimulate early physical growth. As we will see in  Chapter 6 , it is vital for emotional development as well. Therefore, it is not surprising that sensitivity to touch is well-developed at birth. The reflexes listed in  Table 3.4  on  page 107  reveal that the newborn baby responds to touch, especially around the mouth, on the palms, and on the soles of the feet (Humphrey,  1978 ). Newborns even use touch to investigate their world. When small objects are placed in their palms, they can distinguish shape (prism versus cylinder) and texture (smooth versus rough), as indicated by their tendency to hold on longer to objects with an unfamiliar shape or texture (Sann & Streri,  2007 ,  2008 ).

At birth, infants are highly sensitive to pain. If male newborns are circumcised, anesthetic is sometimes not used because of the risk of giving drugs to a very young infant. Babies often respond with a high-pitched, stressful cry and a dramatic rise in heart rate, blood pressure, palm sweating, pupil dilation, and muscle tension (Lehr et al.,  2007 ; Warnock & Sandrin,  2004 ). Brain-imaging research suggests that because of central nervous system immaturity, preterm babies, particularly males, feel the pain of a medical injection especially intensely (Bartocci et al.,  2006 ).

Recent research establishing the safety of certain local anesthetics for newborns promises to ease the pain of these procedures. Offering a nipple that delivers a sugar solution is also helpful; it quickly reduces crying and discomfort in young babies, preterm and full-term alike. Breast milk may be especially effective: Even the smell of the milk of the baby’s mother reduces infant distress to a routine blood-test heelstick more effectively than the odor of another mother’s milk or of formula (Nishitani et al.,  2009 ). And combining sweet liquid with gentle holding by the parent lessens pain even more. Research on infant mammals indicates that physical touch releases endorphins—painkilling chemicals in the brain (Axelin, Salanterä, & Lehtonen,  2006 ; Gormally et al.,  2001 ).

Allowing a baby to endure severe pain overwhelms the nervous system with stress hormones, which can disrupt the child’s developing capacity to handle common, everyday stressors. The result is heightened pain sensitivity, sleep disturbances, feeding problems, and difficulty calming down when upset (Mitchell & Boss,  2002 ).

Taste and Smell.

Facial expressions reveal that newborns can distinguish several basic tastes. Like adults, they relax their facial muscles in response to sweetness, purse their lips when the taste is sour, and show a distinct archlike mouth opening when it is bitter (Steiner,  1979 ; Steiner et al.,  2001 ). These reactions are important for survival: The food that best supports the infant’s early growth is the sweet-tasting milk of the mother’s breast. Not until 4 months do babies prefer a salty taste to plain water, a change that may prepare them to accept solid foods (Mennella & Beauchamp,  1998 ).

Nevertheless, newborns can readily learn to like a taste that at first evoked either a neutral or a negative response. For example, babies allergic to cow’s-milk formula who are given a soy- or other vegetable-based substitute (typically very strong and bitter-tasting) soon prefer it to regular formula (Harris,  1997 ). A taste previously disliked can come to be preferred when it is paired with relief of hunger.

As with taste, certain odor preferences are present at birth. For example, the smell of bananas or chocolate causes a relaxed, pleasant facial expression, whereas the odor of rotten eggs makes the infant frown (Steiner,  1979 ). During pregnancy, the amniotic fluid is rich in tastes and smells that vary with the mother’s diet—early experiences that influence newborns’ preferences. In a study carried out in the Alsatian region of France, where anise is frequently used to flavor foods, researchers tested newborns for their reaction to the anise odor (Schaal, Marlier, & Soussignan,  2000 ). The mothers of some babies had regularly consumed anise during the last two weeks of pregnancy; the other mothers had never consumed it. When presented with the anise odor on the day of birth, the babies of non-anise-consuming mothers were far more likely to turn away with a negative facial expression (see  Figure 3.7 ). These different reactions were still apparent four days later, even though all mothers had refrained from consuming anise during this time.

In many mammals, the sense of smell plays an important role in feeding and in protecting the young from predators by helping mothers and babies identify each other. Although smell is less well-developed in humans, traces of its survival value remain.

Immediately after birth, babies placed face down between their mother’s breasts spontaneously latch on to a nipple and begin sucking within an hour. If one breast is washed to remove its natural scent, most newborns grasp the unwashed breast, indicating that they are guided by smell (Varendi & Porter,  2001 ). At 4 days of age, breastfed babies prefer the smell of their own mother’s breast to that of an unfamiliar lactating mother (Cernoch & Porter,  1985 ). And both breast- and bottle-fed 3- to 4-day-olds orient more to the smell of unfamiliar human milk than to formula milk, indicating that (even without postnatal exposure) the odor of human milk is more attractive to newborns (Marlier & Schaal,  2005 ). Newborns’ dual attraction to the odor of their mother and to that of breast milk helps them locate an appropriate food source and, in the process, begin to distinguish their caregiver from other people.

FIGURE 3.7 Examples of facial expressions of newborns exposed to the odor of anise whose mothers’ diets differed in anise-flavored foods during late pregnancy.

(a) Babies of anise-consuming mothers spent more time turning toward the odor and sucking, licking, and chewing. (b) Babies of non-anise-consuming mothers more often turned away with a negative facial expression.

Hearing.

Newborn infants can hear a wide variety of sounds, and their sensitivity improves greatly over the first few months (Saffran, Werker, & Werner,  2006 ; Tharpe & Ashmead,  2001 ). At birth, infants prefer complex sounds, such as noises and voices, to pure tones. And babies only a few days old can tell the difference between a variety of sound patterns: a series of tones arranged in ascending versus descending order; tone sequences with a rhythmic downbeat (as in music) versus those without; utterances with two versus three syllables; the stress patterns of words (“ma-ma” versus “ma-ma”); happy-sounding speech as opposed to speech with negative or neutral emotional qualities; and even two languages spoken by the same bilingual speaker, as long as those languages differ in their rhythmic features—for example, French versus Russian (Mastropieri & Turkewitz,  1999 ; Ramus,  2002 ; Sansavini, Bertoncini, & Giovanelli,  1997 ; Trehub,  2001 ; Winkler et al.,  2009 ).

Young infants listen longer to human speech than structurally similar nonspeech sounds (Vouloumanos & Werker,  2004 ). And they can detect the sounds of any human language. Newborns make fine-grained distinctions among many speech sounds. For example, when given a nipple that turns on a recording of the “ba” sound, babies suck vigorously and then slow down as the novelty wears off. When the sound switches to “ga,” sucking picks up, indicating that infants detect this subtle difference. Using this method, researchers have found only a few speech sounds that newborns cannot discriminate. Their ability to perceive sounds not found in their own language is more precise than an adult’s (Aldridge, Stillman, & Bower,  2001 ; Jusczyk & Luce,  2002 ). These capacities reveal that the baby is marvelously prepared for the awesome task of acquiring language.

TAKE A MOMENT … Listen carefully to yourself the next time you talk to a young baby. You will probably speak in ways that highlight important parts of the speech stream—use a slow, high-pitched, expressive voice with a rising tone at the ends of phrases and sentences and a pause before continuing. Adults probably communicate this way because they notice that infants are more attentive when they do so. Indeed, newborns prefer speech with these characteristics (Saffran, Werker, & Werner,  2006 ). In addition, they will suck more on a nipple to hear a recording of their mother’s voice than that of an unfamiliar woman and to hear their native language as opposed to a foreign language (Moon, Cooper, & Fifer,  1993 ; Spence & DeCasper,  1987 ). These preferences may have developed from hearing the muffled sounds of the mother’s voice before birth.

Vision.

Vision is the least-developed of the newborn baby’s senses. Visual structures in both the eye and the brain are not yet fully formed. For example, cells in the retina, the membrane lining the inside of the eye that captures light and transforms it into messages that are sent to the brain, are not as mature or densely packed as they will be in several months. The optic nerve that relays these messages, and the visual centers in the brain that receive them, will not be adultlike for several years. And the muscles of the lens, which permit us to adjust our visual focus to varying distances, are weak (Kellman & Arterberry,  2006 ).

As a result, newborns cannot focus their eyes well, and  visual acuity , or fineness of discrimination, is limited. At birth, infants perceive objects at a distance of 20 feet about as clearly as adults do at 600 feet (Slater et al.,  2010 ). In addition, unlike adults (who see nearby objects most clearly), newborn babies see unclearly across a wide range of distances (Banks,  1980 ; Hainline,  1998 ). As a result, images such as the parent’s face, even from close up, look quite blurred.

Although they cannot yet see well, newborns actively explore their environment by scanning it for interesting sights and tracking moving objects. However, their eye movements are slow and inaccurate (von Hofsten & Rosander,  1998 ). Joshua’s captivation with my pink blouse reveals that he is attracted to bright objects. But although newborns prefer to look at colored rather than gray stimuli, they are not yet good at discriminating colors. It will take about four months for color vision to become adultlike (Kellman & Arterberry,  2006 ).

Neonatal Behavioral Assessment

A variety of instruments permit doctors, nurses, and researchers to assess the behavior of newborn babies. The most widely used, T. Berry Brazelton’s  Neonatal Behavioral Assessment Scale (NBAS) , evaluates the newborn’s reflexes, muscle tone, state changes, responsiveness to physical and social stimuli, and other reactions (Brazelton & Nugent,  1995 ). An instrument consisting of similar items, the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS), is specially designed for use with newborns at risk for developmental problems because of low birth weight, preterm delivery, prenatal substance exposure, or other conditions (Lester & Tronick,  2004 ). Scores are used to recommend appropriate interventions and to guide parents in meeting their baby’s unique needs.

The NBAS has been given to many infants around the world. As a result, researchers have learned about individual and cultural differences in newborn behavior and how child-rearing practices can maintain or change a baby’s reactions. For example, NBAS scores of Asian and Native-American babies reveal that they are less irritable than Caucasian infants. Mothers in these cultures often encourage their babies’ calm dispositions through holding and nursing at the first signs of discomfort (Muret-Wagstaff & Moore,  1989 ; Small,  1998 ). The Kipsigis of rural Kenya, who highly value infant motor maturity, massage babies regularly and begin exercising the stepping reflex shortly after birth. These customs contribute to Kipsigis babies’ strong but flexible muscle tone at 5 days of age (Super & Harkness,  2009 ). In Zambia, Africa, close mother–infant contact throughout the day quickly changes the poor NBAS scores of undernourished newborns. When reassessed at 1 week of age, a once unresponsive newborn appears alert and contented (Brazelton, Koslowski, & Tronick,  1976 ).

TAKE A MOMENT … Using these examples, can you explain why a single neonatal assessment score is not a good predictor of later development? Because newborn behavior and parenting combine to influence development, changes in scores over the first week or two of life (rather than a single score) provide the best estimate of the baby’s ability to recover from the stress of birth. NBAS “recovery curves” predict intelligence and absence of emotional and behavior problems with moderate success well into the preschool years (Brazelton, Nugent, & Lester,  1987 ; Ohgi et al.,  2003a ,  2003b ).

In some hospitals, health professionals use the NBAS or the NNNS to help parents get to know their newborns through discussion or demonstration of the capacities these instruments assess. Parents who participate in these programs, compared with no-intervention controls, interact more confidently and effectively with their babies (Browne & Talmi,  2005 ; Bruschweiler-Stern,  2004 ). Although lasting effects on development have not been demonstrated, NBAS-based interventions are useful in helping the parent–infant relationship get off to a good start.

Similar to women in the Zambian culture, this mother of the El Molo people of northern Kenya carries her baby all day, providing close physical contact, a rich variety of stimulation, and ready feeding.

image13 Adjusting to the New Family Unit

Because effective parental care is crucial for infant survival and optimal development, nature helps prepare expectant mothers and fathers for their new role. Toward the end of pregnancy, mothers begin producing the hormone oxytocin, which stimulates uterine contractions; causes the breasts to “let down” milk; induces a calm, relaxed mood; and promotes responsiveness to the baby (Russell, Douglas, & Ingram,  2001 ). And fathers show hormonal changes around the time of birth that are compatible with those of mothers—specifically, slight increases in prolactin (a hormone that stimulates milk production in females) and estrogens (sex hormones produced in larger quantities in females) and a drop in androgens (sex hormones produced in larger quantities in males) (Numan & Insel,  2003 ; Wynne-Edwards,  2001 ). These changes, which are induced by fathers’ contact with the mother and baby, predict positive emotional reactions to infants and paternal caregiving (Feldman et al.,  2010 ; Leuner, Glasper, & Gould,  2010 ).

Although birth-related hormones can facilitate caregiving, their release and effects may depend on experiences, such as a positive couple relationship. Furthermore, humans can parent effectively without experiencing birth-related hormonal changes, as successful adoption reveals. And as we have seen, a great many factors—from family functioning to social policies—are involved in good infant care.

Indeed, the early weeks after the baby’s arrival are full of profound challenges. The mother needs to recuperate from childbirth. If she is breastfeeding, energies must be devoted to working out this intimate relationship. The father must become a part of this new threesome while supporting the mother in her recovery. At times, he may feel ambivalent about the baby, who constantly demands and gets the mother’s attention. And as we will see in  Chapter 6 , siblings—especially those who are young and firstborn—understandably feel displaced. They sometimes react with jealousy and anger.

While all this is going on, the tiny infant is assertive about his urgent physical needs, demanding to be fed, changed, and comforted at odd times of the day and night. The family schedule becomes irregular and uncertain. Yolanda spoke candidly about the changes she and Jay experienced:

·  When we brought Joshua home, he seemed so small and helpless, and we worried about whether we would be able to take proper care of him. It took us 20 minutes to change the first diaper! I rarely feel rested because I’m up two to four times every night, and I spend a good part of my waking hours trying to anticipate Joshua’s rhythms and needs. If Jay weren’t so willing to help by holding and walking Joshua, I think I’d find it much harder.

How long does this time of adjustment to parenthood last? In  Chapter 14 , we will see that when marital relationships are positive, social support is available, and families have sufficient income, the stress caused by the birth of a baby remains manageable. Nevertheless, as one pair of counselors who have worked with many new parents pointed out, “As long as children are dependent on their parents, those parents find themselves preoccupied with thoughts of their children. This does not keep them from enjoying other aspects of their lives, but it does mean that they never return to being quite the same people they were before they became parents” (Colman & Colman,  1991 , p. 198).

image14 SUMMARY

Prenatal Development ( p. 80 )

· List the three periods of prenatal development, and describe the major milestones of each.

· ● The period of the zygote lasts about two weeks, from fertilization until implantation of the blastocyst in the uterine lining. During this time, structures that will support prenatal growth begin to form, including the placenta and the umbilical cord.

· ● During the period of the embryo, weeks 2 through 8, the groundwork is laid for all body structures. The neural tube forms and the nervous system starts to develop. Other organs follow rapidly. By the end of this period, the embryo responds to touch and can move.

· ● The period of the fetus, lasting until the end of pregnancy, involves dramatic increase in body size and completion of physical structures. At the end of the second trimester, most of the brain’s neurons are in place.

· ● The fetus reaches the age of viability at the beginning of the third trimester, between 22 and 26 weeks. The brain continues to develop rapidly, and new sensory and behavioral capacities emerge. Gradually the lungs mature, the fetus fills the uterus, and birth is near.

Prenatal Environmental Influences ( p. 85 )

· Cite factors that influence the impact of teratogens, noting agents that are known teratogens.

· ● The impact of teratogens varies with the amount and length of exposure, genetic makeup of mother and fetus, presence or absence of other harmful agents, and age of the organism at time of exposure. The developing organism is especially vulnerable during the embryonic period.

· ● The most widely used potent teratogen is Accutane, a drug used to treat severe acne. The prenatal impact of other commonly used medications, such as aspirin and caffeine, is hard to separate from other factors correlated with drug taking.

· ● Babies born to users of cocaine, heroin, or methadone are at risk for a wide variety of problems, including prematurity, low birth weight, physical defects, breathing difficulties, and death around the time of birth.

· ● Infants whose parents use tobacco are often born underweight, may have physical defects, and are at risk for long-term attention, learning, and behavior problems. Maternal alcohol consumption can lead to fetal alcohol spectrum disorder (FASD). Fetal alcohol syndrome (FAS) involves slow physical growth, facial abnormalities, and mental impairments. Milder forms—partial fetal alcohol syndrome (p-FAS) and alcohol-related neurodevelopmental disorder (ARND)—affect children whose mothers consumed smaller quantities of alcohol.

· ● Prenatal exposure to high levels of ionizing radiation, mercury, PCBs, lead, and dioxins leads to physical malformations and severe brain damage. Low-level exposure has been linked to cognitive deficits and emotional and behavioral disorders.

· ● Among infectious diseases, rubella causes a wide range of abnormalities. Babies with prenatally transmitted HIV rapidly develop AIDS, leading to brain damage and early death. Cytomegalovirus, herpes simplex 2, and toxoplasmosis can also be devastating to the embryo and fetus.

· Describe the impact of additional maternal factors on prenatal development.

· ● Prenatal malnutrition can lead to low birth weight, organ damage, and suppression of immune system development. Vitamin–mineral enrichment, including folic acid, can prevent prenatal and birth complications.

· ● Severe emotional stress is linked to many pregnancy complications and may permanently alter fetal neurological functioning, thereby magnifying future stress reactivity. Its negative impact can be reduced by providing the mother with social support. Rh factor incompatibility—an Rh-negative mother carrying an Rh-positive fetus—can lead to oxygen deprivation, brain and heart damage, and infant death.

· ● Other than the risk of chromosomal abnormalities in older women, maternal age through the thirties is not a major cause of prenatal problems. Poor health and environmental risks associated with poverty are the strongest predictors of pregnancy complications.

Why is early and regular health care vital during the prenatal period?

· ● Unexpected difficulties, such as preeclampsia, can arise, especially in mothers with preexisting health problems. Prenatal health care is especially critical for women unlikely to seek it, including those who are young and poor.

Childbirth ( p. 96 )

· Describe the three stages of childbirth, the baby’s adaptation to labor and delivery, and the newborn baby’s appearance.

· ● In the first stage of childbirth, contractions widen and thin the cervix. In the second stage, the mother feels an urge to push the baby through the birth canal. In the final stage, the placenta is delivered. During labor, infants produce high levels of stress hormones, which help them withstand oxygen deprivation, clear the lungs for breathing, and arouse them into alertness at birth.

· ● Newborn babies have large heads, small bodies, and facial features that make adults feel like cuddling them. The Apgar Scale assesses the baby’s physical condition at birth.

Approaches to Childbirth ( p. 98 )

· Describe natural childbirth and home delivery, noting benefits and concerns associated with each.

· ● In natural, or prepared, childbirth, the expectant mother and a companion attend classes about labor and delivery, master relaxation and breathing techniques to counteract pain, and prepare for coaching during childbirth. Social support from a partner, relative, or doula reduces the length of labor and the incidence of birth complications.

· ● Home birth is safe for healthy mothers who are assisted by a well-trained doctor or midwife, but mothers at risk for complications are safer giving birth in a hospital.

Medical Interventions ( p. 100 )

· List common medical interventions during childbirth, circumstances that justify their use, and any dangers associated with each.

· ● Fetal monitors help save the lives of many babies at risk for anoxia because of pregnancy and birth complications. When used routinely, however, they may identify infants as in danger who, in fact, are not.

· ● Use of analgesics and anesthetics to control pain, though necessary in complicated deliveries, can prolong labor and may have negative affects on the newborn’s adjustment.

· ● Cesarean deliveries are warranted by medical emergency or serious maternal illness and for many babies who are in breech position. However, many unnecessary cesareans are performed.

Preterm and Low-Birth-Weight Infants ( p. 101 )

· Describe risks associated with preterm birth and low birth weight, along with effective interventions.

· ● Low birth weight, most common in infants born to poverty-stricken women, is a major cause of neonatal and infant mortality and many developmental problems. Compared with preterm infants, whose weight is appropriate for time spent in the uterus, small-for-date infants usually have longer-lasting difficulties.

· ● Some interventions provide special stimulation in the intensive care nursery. Others teach parents how to care for and interact with their babies. Preterm infants in stressed, low-income households need long-term, intensive intervention.

Birth Complications, Parenting, and Resilience ( p. 105 )

What factors predict positive outcomes in infants who survive a traumatic birth?

· ● When infants experience birth trauma, a supportive home environment can help restore their growth. Even infants with fairly serious birth complications can recover with the help of favorable experiences with parents, relatives, neighbors, and peers.

The Newborn Baby’s Capacities ( p. 106 )

Describe the newborn baby’s reflexes and states of arousal, including sleep characteristics and ways to soothe a crying baby.

· ● Reflexes are the newborn baby’s most obvious organized patterns of behavior. Some have survival value, others provide the foundation for voluntary motor skills, and still others help parents and infants establish gratifying interaction.

· ● Newborns move in and out of five states of arousal but spend most of their time asleep. Sleep includes at least two states, rapid-eye-movement (REM) sleep and non-rapid-eye-movement (NREM) sleep. Newborns spend about 50 percent of sleep time in REM sleep, which provides them with stimulation essential for central nervous system development.

· ● A crying baby stimulates strong feelings of discomfort in nearby adults. The intensity of the cry and the experiences that led up to it help parents identify what is wrong. Once feeding and diaper changing have been tried, a highly effective soothing technique is lifting the baby to the shoulder and rocking and walking.

Describe the newborn baby’s sensory capacities.

· ● The senses of touch, taste, smell, and sound are well-developed at birth. Newborns use touch to investigate their world, are sensitive to pain, prefer sweet tastes and smells, and orient toward the odor of their own mother’s lactating breast.

· ● Newborns can distinguish a variety of sound patterns and prefer complex sounds. They are especially responsive to human speech, can detect the sounds of any human language, and prefer their mother’s voice.

· ● Vision is the least developed of the newborn’s senses. At birth, focusing ability and visual acuity are limited. In exploring the visual field, newborn babies are attracted to bright objects but have difficulty discriminating colors.

Why is neonatal behavioral assessment useful?

· ● The most widely used instrument for assessing the behavior of the newborn infant, Brazelton’s Neonatal Behavioral Assessment Scale (NBAS), has helped researchers understand individual and cultural differences in newborn behavior. Sometimes it is used to teach parents about their newborn’s capacities.

Adjusting to the New Family Unit ( p. 115 )

Describe typical changes in the family after the birth of a new baby.

· ● The new baby’s arrival is exciting but stressful, as the mother recuperates from childbirth and the family schedule becomes irregular and uncertain. When parents have a positive relationship as well as social support and adequate income, adjustment problems are usually temporary.

Case Studies in Assessment

July 9, 2025/in Psychology Questions /by Besttutor

Prior to beginning work on this discussion, read the assigned chapters from the text. It is highly recommended that you review each of the brief Blumenfeld (2012) video clips demonstrating the administration of a mental status examination. These are listed in the recommended resources and may require that you download Quicktime in order to view them. Although not required, these videos show the administration of a mental status exam and may prove helpful in this discussion.

Access the Barnhill (2014) DSM-5 Clinical Cases e-book in the DSM-5 library, and select one of the case studies. The case study you select must be one in which the client could be assessed using one or more of the assessment instruments discussed in this week’s reading.

For this discussion, you will take on the role of a psychology intern at a mental health facility working under the supervision of a licensed psychologist. In this role, you will conduct a psychological evaluation of a client referred to you for a second opinion using valid psychological tests and assessment procedures. The case study you select from the textbook will serve as the information provided to you from the professional who previously evaluated the client (e.g., the psychologist or psychiatrist).

In your initial post, begin with a paragraph briefly summarizing the main information about the case you selected. Evaluate and describe the ethical and professional interpretation of any assessment information presented in the case study. Devise an assessment battery for a psychological evaluation that minimally includes a clinical interview, mental status exam, intellectual assessment, observations of the client, and at least two assessment instruments specific to the diagnostic impressions (e.g., attention deficit/hyperactivity disorder, post-traumatic stress disorder, autism spectrum disorder, etc.). The assessment battery must include at least one approach to assessing your client which is different from the assessments previously administered. The assessment plan must be presented as a list of recommended psychological tests and assessment procedures with a brief sentence explaining the purpose of each test or procedure. Following the list of tests and assessment procedures you recommend for your client, compare the assessment instruments that fall within the same categories (e.g., intellectual or achievement), and debate the pros of cons of the instruments and procedures you selected versus the instruments and procedures reported by the referring professional.

Guided Response: Review several of your colleagues’ posts, and respond to at least two of your peers by 11:59 p.m. on Day 7 of the week. You are encouraged to post your required replies earlier in the week to promote more meaningful interactive discourse in this discussion. Was your colleague’s proposed assessment battery appropriate for the case they were referred? Evaluate the instrument(s) suggested by your colleague. Would these measures provide reliable, valid, and culturally appropriate results for the given scenario? Use your research to support your assertions. What other measure(s) would you suggest your colleague use in this situation? Continue to monitor the discussion forum until 5:00 p.m. Mountain Standard Time (MST) on Day 7 of the week and respond to anyone who replies to your initial post.

July 9, 2025/in Psychology Questions /by Besttutor

You have had the opportunity to work as a member of a small group as your cohort developed your group proposal concept. During your work in your cohort group, you made notes and observed the dynamics which emerged while working together in a small group. You have paid special attention and taken notes on your role in your small group in order to achieve the heightened self-awareness required to become a skilled group leader.

You also had the opportunity to practice your group leaderships skills at each stage of group development using Theravue. You will now use your knowledge of small group process and your newly acquired group leadership skills to reflect on your progress as a group leader as you complete your Group Leadership Self-Assessment for submission in Week 11.

To Prepare:

  • Review your notes from your cohort group work in Weeks 3 and 4.

  • Using your knowledge of group dynamics and group leadership skills, consider your growth as a group member and group leader.
  • Review the Group Leadership Self-Reflection Guidelines to guide your Week 11 Group Leadership Self-Assessment Assignment.
