1. Jalynn is in the last half of the first month of her pregnancy. Which of the following is developing the fastest?

• A. circulatory system
• B. endocrine system
• C. nervous system
• D. skin

Correct answer: C

Rationale: During the last half of the first month of pregnancy, the nervous system develops the fastest among the options provided. This rapid development of the nervous system is crucial for the overall growth and functioning of the fetus. The nervous system includes the brain and spinal cord, which are essential for various bodily functions and will continue to develop throughout the pregnancy. The circulatory system, although important, does not develop at the fastest rate during this stage. The endocrine system and skin also play significant roles in the development of the fetus but are not the systems that develop the fastest in the last half of the first month of pregnancy.

2. A theory of development __________.

• A. illustrates the ultimate truth about human behavior
• B. describes, explains, and predicts behavior
• C. explains all aspects of human growth
• D. does not require scientific verification

Correct answer: B

Rationale: A theory of development describes, explains, and predicts behavior. It provides a framework for understanding how individuals grow and change over time. The purpose of a theory is not to illustrate ultimate truth or explain all aspects of human growth, but rather to help researchers and practitioners make sense of and predict human behavior. Theories are expected to be tested and refined through scientific verification. Choice A is incorrect because theories do not necessarily illustrate ultimate truth. Choice C is incorrect as theories focus on behavior and development, not all aspects of human growth. Choice D is incorrect because scientific verification is essential for theories to be valid and reliable.

3. 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.

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. The harm done by teratogens __________.

• A. is straightforward and predictable
• B. is usually apparent at birth
• C. rarely goes beyond physical damage
• D. depends on age at the time of exposure

Correct answer: D

Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.
