What increases from early to middle adulthood?

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.

Correct Answer: D

Rationale: The correct answer is 'D: deficits.' Most cognitive aging research has indeed focused on deficits rather than stability, gains, or competence. Studies have consistently shown that deficits in processing speed and memory are common in aging individuals, making it a primary area of interest in research. Choices A, B, and C are incorrect because cognitive aging research primarily aims to understand and address deficits associated with aging rather than focusing on stability, gains, or overall competence.

Correct Answer: D

Rationale: The correct answer is D. Kohlberg's moral stages are not strictly sequential but rather overlap and are more fluid, much like Piaget's cognitive stages. Choices A, B, and C are incorrect because Kohlberg's stages do not follow a neat, predictable, or highly organized pattern, as they can be revisited and experienced in varying orders.

Correct Answer: C

Rationale: The correct answer is C: 'self-indulgence'. Stagnation in Erikson's midlife stage refers to a lack of growth and self-indulgence, leading to a feeling of unproductiveness. This contrasts with 'role confusion' (A), which is associated with Erikson's adolescence stage, 'selflessness' (B) which is a positive trait, and 'guilt and shame' (D) which are emotions typically associated with earlier stages of development.

Correct Answer: A

Rationale: Physical activity is known to have a positive impact on mental health by reducing symptoms of anxiety and depression. Choice B is incorrect because physical activity generally improves both mood and alertness. Choice C is incorrect as physical activity tends to increase mood, alertness, and energy levels. Choice D is incorrect as physical activity actually increases neural activity in the cerebral cortex, which is associated with improved cognitive function and mental well-being.
