1. Which of the following best describes a sequential design?

• A. Does not address diversity in developmental outcomes.
• B. Permits researchers to check if cohort effects are operating.
• C. Is less efficient than a longitudinal design.
• D. Makes cross-sectional, but not longitudinal, comparisons.

Correct answer: B

Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.

2. Katie wonders when she will first be able to hear her fetus's heartbeat through a stethoscope. You tell her that this should happen by the __________.

• A. fourth week of pregnancy
• B. third month of pregnancy
• C. end of the second trimester
• D. beginning of the third trimester

Correct answer: B

Rationale: The correct answer is the third month of pregnancy (choice B). During the third month of pregnancy, which is around 9-12 weeks, a fetal heartbeat can typically be heard using a stethoscope. This is an exciting milestone for expectant parents as it provides reassurance about the baby's well-being. Choices A, C, and D are incorrect because by the fourth week of pregnancy, the fetal heartbeat is not usually detectable with a stethoscope. The end of the second trimester and the beginning of the third trimester are too late in the pregnancy timeline for this milestone.

3. Newborns of smoking mothers __________.

• A. are more attentive to sounds
• B. display more muscle tension
• C. less often have colic
• D. are less excitable when visually stimulated Answer: B Page Ref: 84 Skill Level: Understand known or suspected teratogens. Copyright © 2018 Laura E. Berk. All Rights Reserved. 12 Test Bank for Berk, Development Through the Lifespan, 7e Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: B

Rationale: Newborns of smoking mothers display more muscle tension. This is because nicotine in cigarettes can lead to increased muscle tension in babies, which can affect their physical development and potentially lead to future health issues. This is one of the negative effects of smoking during pregnancy on the developing fetus.

4. To study the impact of biological aging on motor skills, researchers focus on __________.

• A. sedentary adults
• B. competitive athletes
• C. men in their mid- to late thirties
• D. women in their childbearing years

Correct answer: B

Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.

5. Dr. O'Connor wants 90-year-old Mr. Takashi to participate in a research study that involves moderate risks. Mr. Takashi is incapable of consenting. Which statement best expresses your advice regarding Mr. Takashi's participation in the study?

• A. He should not be allowed to participate in the study under any circumstances.
• B. He should be allowed to participate in the study regardless of the benefit.
• C. He should be allowed to participate in the study only if his participation will benefit others.
• D. He should be allowed to participate in the study only if it is likely to benefit him directly.

Correct answer: D

Rationale: Mr. Takashi should be allowed to participate in the study only if it is likely to benefit him directly. This decision aligns with the principle of beneficence in research ethics, which emphasizes maximizing benefits and minimizing risks for research participants. Since Mr. Takashi is incapable of giving consent, his participation should be based on the likelihood of direct benefits to him rather than solely for the benefit of others or solely for research purposes. Option A is too restrictive and does not consider potential benefits to Mr. Takashi. Option B is flawed as it disregards the need for the study to benefit Mr. Takashi. Option C focuses on benefiting others, which is not the primary consideration when the participant cannot give consent.
