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.

Which of the following is the best available predictor of infant survival and healthy development?
- A. Birth length
- B. Combined Apgar score
- C. Delivery date
- D. Birth weight
Correct Answer: D
Rationale: The correct answer is 'Birth weight.' Birth weight is a crucial indicator of an infant's chances of survival and well-being. Low birth weight is associated with various health risks and developmental challenges. Birth length (choice A) is not as significant in predicting infant outcomes as birth weight. The Combined Apgar score (choice B) is a measure of the newborn's health status at birth, not a predictor of long-term survival and development. Delivery date (choice C) is important for determining gestational age but is not as directly related to infant survival and healthy development as birth weight.
What increases from early to middle adulthood?
- A. Possible selves
- B. Self-doubt
- C. Destructiveness
- D. Autonomy
Correct Answer: A
Rationale: Possible selves are ideas about what one might become in the future, which increase during the transition from early to middle adulthood. This period is characterized by individuals exploring and considering different potential future selves. Self-doubt (choice B) typically decreases as individuals become more confident and self-assured in middle adulthood. Destructiveness (choice C) is not a common developmental trend during this period. Autonomy (choice D) is a concept related to independence and self-governance, which may develop over a person's lifespan but does not specifically increase during the transition from early to middle adulthood.
According to Jean Piaget, what is the balance between internal structures and information that children encounter in their everyday worlds?
- A. imitation
- B. adaptation
- C. cognition
- D. equilibrium
Correct Answer: D
Rationale: According to Jean Piaget, equilibrium is the balance between what children already know (internal structures) and the new information they encounter. Imitation (choice A) is not directly related to this concept. Adaptation (choice B) involves adjusting to new information and is part of Piaget's theory, but it does not specifically refer to the balance between internal structures and external information. Cognition (choice C) is a broader term that encompasses mental processes, including thinking, learning, and problem-solving, but it is not specifically about the balance between internal structures and external information as equilibrium is.
Nine-month-old Avery can retrieve his ball when his mother hides it under a blanket. Avery has begun to master __________.
- A. the tertiary circular reaction
- B. reflexive schemes
- C. object permanence
- D. deferred imitation
Correct Answer: C
Rationale: Avery demonstrating the ability to retrieve his ball hidden under a blanket indicates that he has started to understand object permanence. Object permanence is the concept that objects continue to exist even when they are out of sight. This milestone typically occurs around 8-12 months of age. The other choices are incorrect. Option A, the tertiary circular reaction, is related to Piaget's theory of sensorimotor development but does not specifically address object permanence. Reflexive schemes (Option B) refer to simple, reflex-like behaviors and are not directly linked to object permanence. Deferred imitation (Option D) involves the ability to imitate actions observed at an earlier time, which is a different developmental milestone compared to object permanence.
By age 2, children __________.
- A. take turns in face-to-face interaction
- B. can infer a speaker's indirectly expressed intention
- C. adjust their speech to fit the age of their listeners
- D. adjust their speech to fit the social status of their listeners
Correct Answer: C
Rationale: By age 2, children are capable of adjusting their speech to fit the age of their listeners, showing early social cognition. Choice A is incorrect because taking turns in face-to-face interaction typically develops later in childhood. Choice B is incorrect as the ability to infer a speaker's indirectly expressed intention is a more advanced skill not typically seen at age 2. Choice D is also incorrect as children at age 2 are not developmentally ready to adjust their speech based on the social status of their listeners.
