Correct Answer: D

Rationale: In defining a mental disorder, deviance refers to behavior that is culturally unexpected or violates social norms. This means that the individual displays behaviors that are not typical or acceptable within their specific culture or society. Choices A, B, and C are incorrect because they do not directly relate to the concept of deviance in the context of defining a mental disorder. The amount of suffering, inability to fulfill a role, or capacity to cause harm are important considerations in understanding mental disorders but are not specifically related to deviance.

Correct Answer: C

Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.

Correct Answer: B

Rationale: Dr. Smythe's belief that understanding the purpose of taste in survival is more critical than focusing on the elementary components aligns with the functionalist approach to psychology. Functionalism emphasizes understanding the purpose or function of mental processes and behavior, rather than just analyzing their individual components. This approach looks at how mental processes help individuals adapt to their environment and survive. Therefore, choices A, C, and D are incorrect because they do not prioritize understanding the purpose of mental processes and behavior in the context of survival.

Correct Answer: B

Rationale: The correct answer is B.F. Skinner. Skinner proposed the theory of operant conditioning, where behavior is shaped by its consequences. Positive outcomes increase the likelihood of a behavior being repeated, while neutral or negative outcomes decrease it. Sigmund Freud (choice A) is known for his psychoanalytic theory, Carl Rogers (choice C) for person-centered therapy, and Abraham Maslow (choice D) for the hierarchy of needs.

Correct Answer: A

Rationale: A psychologist interested in the psychological effect of aging would most likely specialize in developmental psychology. Developmental psychology focuses on studying the psychological changes that occur throughout a person's lifespan, including the effects of aging. Experimental psychology primarily deals with conducting experiments to study behavior and cognitive processes. Cognitive psychology focuses on mental processes like perception, memory, and problem-solving. Psychometrics involves the measurement of psychological variables such as intelligence, aptitude, and personality traits, but it does not specifically address the psychological effects of aging as in developmental psychology.
