1. 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.

2. Self-reports __________.

• A. use a flexible, conversational style to probe for the participant's point of view
• B. describe the entire stream of behavior—everything said and done over a certain time period
• C. range from relatively unstructured interviews to highly structured interviews, questionnaires, and tests
• D. bring together a wide range of information on one person, including interviews, observations, and test scores

Correct answer: C

Rationale: Self-reports can range from relatively unstructured interviews to highly structured interviews, questionnaires, and tests. This variety allows researchers to collect information from participants in different ways, depending on the research goals and the type of information being sought. Choices A, B, and D are incorrect because they do not accurately describe the range and flexibility of self-reports as outlined in the field of research methodology.

3. School-age children master concrete operational tasks ________.

• A. all at once
• B. gradually, in a continuum of acquisition
• C. much later than Piaget believed
• D. after they master abstract thinking

Correct answer: B

Rationale: Correct answer: School-age children master concrete operational tasks gradually, in a continuum of acquisition. Piaget's theory suggests that children develop cognitive abilities in stages, with concrete operational tasks being acquired gradually as part of this process. Choices A, C, and D are incorrect because concrete operational tasks are not typically mastered all at once, much later than Piaget believed, or necessarily after mastering abstract thinking.

4. Lily weighed 8 pounds and was 21 inches long at birth. She was __________ than the average baby.

• A. heavier but shorter
• B. heavier and longer
• C. lighter but longer
• D. lighter and shorter

Correct answer: B

Rationale: Lily weighed 8 pounds and was 21 inches long at birth. Being both heavier and longer than average babies typically are at birth, Lily would be considered heavier and longer compared to the average baby. This makes choice B, 'heavier and longer,' the correct answer. Choices A, C, and D are incorrect because Lily was not shorter or lighter than the average baby at birth.

5. The term teratogen refers to __________.

• A. any environmental agent that causes damage during the prenatal period
• B. a limited time span during which a part of the body is biologically prepared to develop rapidly
• C. a rapid period of prenatal neurological development
• D. a synthetic hormone used to prevent miscarriage

Correct answer: A

Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.
