1. __________ may heighten the effects of a high-fat diet.

• A. Sex hormones
• B. Over-the-counter medications
• C. Free radicals
• D. Low body weight

Correct answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.

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. Bernadette, a participant in a longitudinal study, became quite familiar with the test over time and, as a result, her performance improved. This limitation of longitudinal research is known as __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 34 Test Bank for Berk, Development Through the Lifespan, 7e

• A. biased sampling
• B. practice effects
• C. random assignment
• D. cohort effects Answer: B Page Ref: 35 Skill Level: Apply Topic: Studying Development Difficulty Level: Moderate

Correct answer: B

Rationale: Practice effects refer to the phenomenon where participants in a longitudinal study show improvement in test performance over time due to becoming familiar with the tasks or test materials. This can be considered a limitation as it may distort the results by showing an artificial improvement rather than a true developmental change.

4. Piaget's _________ stage is the most complex period of development.

• A. sensorimotor
• B. preoperational
• C. concrete operational
• D. formal operational

Correct answer: D

Rationale: The formal operational stage in Piaget's theory is characterized by abstract reasoning, hypothetical thinking, and logical reasoning. This stage represents the most complex period of cognitive development according to Piaget. Choices A, B, and C refer to earlier stages in Piaget's theory and do not involve the level of abstract thinking and logical reasoning seen in the formal operational stage.

5. 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.
