Dr. Kostel believes that development takes place in stages. This belief is consistent with the __________ perspective.

Correct Answer: C

Rationale: Dr. Kostel's belief in stage-based development aligns with the discontinuous perspective, which sees development as a series of distinct stages. The continuous perspective (choice B) suggests development as a smooth and gradual process without distinct stages. The nature perspective (choice D) focuses on genetic and hereditary influences on development. The nurture perspective (choice A) emphasizes the impact of environment and upbringing on development, which is not directly related to the belief in stage-based development.

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.

Correct Answer: A

Rationale: The correct answer is A: 'Avoidant.' Avoidant coping refers to strategies that involve avoiding the problem and focusing more on emotions. This type of coping mechanism can often lead to negative outcomes as individuals may engage in self-blaming, impulsive behaviors, or seek escapist routes rather than addressing the issue directly. Choice B, 'Ineffective,' is a broad term and does not specifically capture the characteristics described in the question. Choice C, 'Problem-focused,' is the opposite of avoidant coping as it involves actively addressing the issue at hand. Choice D, 'Flexible,' does not align with the description provided, as flexibility in coping involves adapting strategies based on the situation, not necessarily being emotion-focused, self-blaming, impulsive, or escapist.

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.

Correct Answer: B

Rationale: Basic emotions like happiness, sadness, and anger are universal across humans, meaning they are experienced by people worldwide regardless of cultural differences. These emotions are not limited to a specific group of individuals or exclusive to humans; they are observed in various species. Choice A is incorrect because basic emotions actually appear early in life, not specifically in the middle of the second year. Choice C is incorrect as basic emotions are not exclusive to humans but are observed in other animals as well. Choice D is incorrect because basic emotions do not necessarily involve injury to our sense of self, but rather represent fundamental and instinctual feelings that are part of human nature.
