1. The yolk sac __________.

• A. forms during the third trimester of pregnancy
• B. is the outer ring of cells that surrounds the blastocyst Copyright © 2018 Laura E. Berk. All Rights Reserved. 3 Test Bank for Berk, Development Through the Lifespan, 7e
• C. produces blood cells until the organs are mature enough to take over this function
• D. contains one large vein that delivers blood loaded with nutrients and two arteries that remove waste Answer: C Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. During the third stage of labor, __________.

• A. the cervix thins to nothing
• B. uterine contractions begin
• C. the placenta is delivered
• D. the baby is born

Correct answer: C

Rationale: During the third stage of labor, the correct answer is C, the placenta is delivered. This stage occurs after the baby is born and involves the expulsion of the placenta from the uterus. Choice A is incorrect because the thinning of the cervix to nothing typically occurs during the first stage of labor. Choice B is incorrect as uterine contractions usually begin during the first stage of labor to help with the dilation of the cervix. Choice D is incorrect because the baby is typically born in the second stage of labor, not the third.

3. The influence of situational factors on moral judgments indicates that like Piaget's cognitive stages, Kohlberg's moral stages are __________.

• A. predictable and universal
• B. highly organized and sequential
• C. attained in a neat, stepwise fashion
• D. loosely organized and overlapping

Correct answer: D

Rationale: The correct answer is D. Kohlberg's moral stages are not strictly sequential but rather overlap and are more fluid, much like Piaget's cognitive stages. Choices A, B, and C are incorrect because Kohlberg's stages do not follow a neat, predictable, or highly organized pattern, as they can be revisited and experienced in varying orders.

4. One criticism of the information-processing approach is that it __________.

• A. underestimates the individual's contribution to his or her own development
• B. ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence
• C. underestimates the competencies of infants and preschoolers, focusing on older children and adolescents
• D. is better at analyzing thinking into its components than at putting them back together into a comprehensive theory

Correct answer: B

Rationale: The criticism that the information-processing approach ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence, suggests a limitation of the theory in not fully acknowledging that cognitive development continues throughout the lifespan. This criticism highlights a potential drawback of the approach in terms of its understanding of cognitive changes beyond adolescence. Choice A is incorrect because the criticism is not about underestimating the individual's contribution. Choice C is also incorrect as the criticism is not related to age-specific competencies. Choice D is incorrect as it focuses on a different aspect of the information-processing approach.

5. What is a major disadvantage of cross-sectional research?

• A. Age-related changes cannot be examined.
• B. Participants often drop out before the study is over.
• C. Factors affecting individual development cannot be explored.
• D. Practice effects often cause biased findings.

Correct answer: C

Rationale: One major disadvantage of cross-sectional research is that factors affecting individual development cannot be explored thoroughly. Cross-sectional research involves comparing different groups of people at one specific point in time, and does not allow for tracking individual changes over time. This limitation means that the unique influences and trajectories of individual development may be overlooked in cross-sectional studies. Choices A, B, and D are incorrect. Choice A is not a major disadvantage of cross-sectional research as age-related changes can still be compared across different groups in this type of study. Choice B, while a potential issue in any study, is not specific to cross-sectional research. Choice D refers to a different type of bias caused by repeated testing rather than a major disadvantage of cross-sectional research.
