Correct Answer: A

Rationale: The correct answer is A, the behavioral perspective. This perspective focuses on how environmental stimuli influence behavior, making it suitable for studying how anxiety-inducing stimuli affect eating behavior. The psychodynamic perspective (choice B) would focus more on unconscious processes and early life experiences. The humanistic perspective (choice C) emphasizes personal growth and self-actualization. The functionalist perspective (choice D) is more related to the study of the purpose of behavior and mental processes in adapting to the environment.

Correct Answer: B

Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.

Correct Answer: C

Rationale: The correct answer is C: Structuralism. Structuralism, as introduced by Wundt, aimed to break down mental processes into their most basic elements. This aligns with the idea of breaking the conscious experience into its fundamental components. Choice A, Behaviorism, focuses on observable behavior and not on breaking down conscious experience. Choice B, Functionalism, emphasizes the purpose of behavior rather than breaking it down into basic elements. Choice D, Psychoanalysis, delves into unconscious processes and conflicts, which is different from breaking down conscious experiences into basic elements.

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.

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.
