Correct Answer: C

Rationale: The correct answer is C. This scenario exemplifies a critical period in development. Critical periods are specific times in an individual's life when certain events have a profound impact on their development. In this case, the events surrounding the departure of the U.S. armed forces from Saigon in 1975 had a lasting influence on the children living there at that time. Choices A, B, and D are incorrect. Normative age-graded influence refers to events that are common to people of a particular age group, the social clock relates to the culturally preferred timing of social events, and a sensitive period is a time when an individual is more susceptible to environmental influences but does not result in lifelong consequences as with critical periods.

Correct Answer: C

Rationale: The correct answer is C: Humanism. Humanism is a school of psychology that focuses on the positive aspects of human nature, emphasizing personal growth, self-actualization, and the inherent goodness in individuals. Behaviorism (choice A) primarily focuses on observable behaviors and conditioning, functionalism (choice B) emphasizes the functions of consciousness and behavior adaptation, and psychoanalysis (choice D) delves into unconscious thoughts and childhood experiences, rather than having a fundamentally positive view of human nature.

Correct Answer: C

Rationale: The correct answer is C: Secondary circular reactions. Secondary circular reactions are repeated actions that infants engage in to trigger a response from the environment, such as the baby cooing to make the mom smile. This behavior is characterized by a focus on the external environment and the repetition of actions to achieve a desired response. Choices A, B, and D are incorrect. Reflexes (choice A) are automatic, involuntary responses to a stimulus, while primary circular reactions (choice B) involve the repetition of actions primarily for the infant's own enjoyment rather than to elicit a response from the environment. Tertiary circular reactions (choice D) refer to the experimentation with new behaviors and variations in the way the infant interacts with the environment.

Correct Answer: A

Rationale: The correct answer is A, Functionalism. Functionalism, founded by William James, emphasizes understanding the purpose and adaptive function of behavior. This school of psychology focuses on how mental processes help individuals adapt to their environment. Choice B, Behaviorism, is incorrect as behaviorism emphasizes observable behaviors rather than the purpose behind them. Choice C, Neodynamism, is not a recognized school of psychology. Choice D, Psychoanalysis, founded by Sigmund Freud, focuses on unconscious processes and early childhood experiences, not specifically on the purpose of behavior.
