Correct Answer: B

Rationale: The correct answer is B: Social clock; ageism. A social clock refers to the normal sequence of life events in a culture, and not meeting these norms can result in ageism. Choice A is incorrect because normative age-graded influence is not directly related to sexism. Choice C is incorrect as critical period refers to specific time frames for development, not a set of age norms. Choice D, sensitive period, does not directly relate to the concept described in the question.

Correct Answer: A

Rationale: Oliver's roommate holds a humanistic perspective. This perspective emphasizes human uniqueness and may devalue information obtained from animal studies when studying human experiences. The humanistic perspective focuses on subjective experiences, free will, and personal growth, which aligns with his roommate's belief that animal studies won't provide meaningful information about human experiences. Choice B, an evolutionary perspective, would focus on the role of evolution in shaping behavior, not directly related to the roommate's view. Choices C and D, biological and cognitive perspectives respectively, do not directly address the roommate's skepticism toward using animal studies to understand human motivation.

Correct Answer: D

Rationale: The correct answer is D, 'Long-term memory.' In the 5th substage of sensorimotor development, Piaget refers to 'experimentation' as tertiary circular reactions, where the infant tries out new ways of playing with or manipulating objects. This stage involves exploring and testing different ways of interacting with the world to understand cause and effect relationships. Choices A, B, and C are incorrect as they do not align with Piaget's concept of tertiary circular reactions and experimentation in the sensorimotor stage of development.

Correct Answer: C

Rationale: The correct answer is C: 'Be unexpected.' School phobia in children is often associated with separation anxiety disorder, leading to unexpected and intense fear or anxiety about attending school. Choices A and B are incorrect because school phobia does not necessarily occur every time or most of the time when in a specific situation; it is more about the unexpected fear related to attending school. Choice D is also incorrect because school phobia is characterized by an unexpected and overwhelming fear of school, not an expected or anticipated reaction.

Correct Answer: C

Rationale: The correct answer is C. Social psychology focuses on how individuals relate to each other, influence each other, and interact within social groups. This field is more concerned with social interactions and behaviors rather than physical or genetic factors influencing behavior (choice A), internal factors leading to consistent behavior (choice B), or changes in behavior and mental processes over a lifetime (choice D). Therefore, the most appropriate area of interest for Larry, being a graduate student in social psychology, would be how people relate to and influence each other.
