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. Developmental social neuroscience __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 17 Test Bank for Berk, Development Through the Lifespan, 7e

• A. involves the design of flowcharts to map the precise steps individuals use to complete tasks
• B. emphasizes that preschoolers’ thinking is full of faulty logic because they engage in hands-on exploration
• C. is devoted to studying the relationship between changes in the brain and emotional and social development
• D. involves the study of brain activity and the individual’s linear and logical cognitive processing patterns Answer: C Page Ref: 20 Skill Level: Understand Topic: Recent Theoretical Perspectives Difficulty Level: Moderate

Correct answer: C

Rationale: Developmental social neuroscience is dedicated to examining the connection between changes in the brain and emotional and social development. This field of study focuses on how the brain's development influences an individual's social and emotional behavior. By studying brain activity alongside emotional and social development, researchers can gain insights into how these aspects are interrelated and how they impact one another.

3. 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.

4. Which statement about the harm done by teratogens is true?

• A. Passive smoking can be harmful to the developing fetus.
• B. The genetic makeup of the mother and the developing organism plays an important role.
• C. The negative impact of teratogens is usually reversible.
• D. The most serious defects occur in the germinal period.

Correct answer: B

Rationale: The statement that the genetic makeup of the mother and the developing organism plays an important role in the harm done by teratogens is true. Genetic factors can influence susceptibility to teratogens, and the interaction between genetic and environmental factors plays a significant role in determining the impact on the developing fetus. This highlights the importance of considering both genetic and environmental influences when assessing risks to prenatal development. Choice A is incorrect as passive smoking can indeed be harmful to the developing fetus. Choice C is incorrect as the negative impact of teratogens is often not reversible. Choice D is incorrect as serious defects can occur throughout prenatal development, not just in the germinal period.

5. Why do young infants usually cry?

• A. because they are bored
• B. in shrill, piercing tones
• C. because of physical needs
• D. all night long

Correct answer: C

Rationale: Young infants usually cry because of physical needs such as hunger, discomfort, or needing to be changed. It is their way of communicating these needs to their caregivers as they are unable to do so in any other way. Choice A is incorrect because infants cry primarily to communicate physical needs, not because they are bored. Choice B is incorrect because the tone of the cry is not the reason why infants cry. Choice D is incorrect because infants cry for various physical needs, not necessarily all night long.
