Human Growth and Development Exam 1

1. Low-level radiation, resulting from industrial leakage or medical X-rays, __________.

A. is harmful only when combined with other teratogens
B. can increase the risk of childhood cancer
C. rarely causes lasting damage
D. is safe during the last trimester

Correct answer: B

Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.

2. What is one strength of the cross-sectional design?

A. It provides evidence about individual trends.
B. It cannot be threatened by cohort effects.
C. It is not plagued with dropout or practice effects.
D. It permits longitudinal comparisons. Answer: C Page Ref: 34 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate

Correct answer: C

Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.

3. Students who are foreign-born or first-generation Americans _______ than students of native-born parents.

A. are more likely to commit delinquent and violent acts
B. are more likely to be obese
C. often achieve in school as well as or better
D. tend to report lower self-esteem

Correct answer: C

Rationale: According to the information provided in the text box 'CULTURAL INFLUENCES: Immigrant Youths: Adapting to a New Land' on page 32, students who are foreign-born or first-generation Americans often achieve in school as well as or better than students of native-born parents. This implies that they excel academically despite facing challenges related to cultural adaptation and assimilation. Choices A, B, and D are incorrect because the provided information specifically highlights the academic achievement of foreign-born or first-generation American students compared to students of native-born parents, not their likelihood of committing delinquent acts, obesity rates, or self-esteem levels.

4. 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.

5. Today, Albert Bandura's theory stresses the importance of __________.

A. behavior modification
B. punishment
C. cognition
D. reinforcement

Correct answer: C

Rationale: Albert Bandura's theory emphasizes the role of cognition in learning through observation. It highlights the significance of mental processes such as attention, memory, and motivation in shaping behavior. Choice A, behavior modification, focuses more on changing specific behaviors through various techniques. Choice B, punishment, involves the application of negative consequences to reduce the likelihood of a behavior occurring. Choice D, reinforcement, centers on the use of rewards or punishments to increase or decrease the probability of a behavior.
