Correct Answer: A

Rationale: The correct answer is A: Abstraction. Pretending that a block is a car demonstrates abstraction, where one object is used to represent another. Choice B, Preoperational, refers to Piaget's stage of cognitive development. Choice C, Overextension, involves using a word in a broader context than is appropriate. Choice D, Semiotic, refers to the use of symbols to represent ideas or concepts, which is not directly related to the scenario described in the question.

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: C

Rationale: Sigmund Freud developed psychoanalysis, not behavior modification, primal therapy, or rational-emotive therapy, as an innovative method for treating psychological problems. Psychoanalysis focuses on exploring unconscious motivations to understand and address psychological disorders, making it the correct answer. Behavior modification involves changing behavior through conditioning techniques, primal therapy emphasizes expressing repressed emotions, and rational-emotive therapy aims to identify and change irrational beliefs.

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: D

Rationale: The correct answer is D, a social psychologist. Social psychologists focus on how societal factors, including norms and expectations, influence behaviors and attitudes. In this case, studying the attitudes of men and women toward traditional sex roles aligns with the research domain of social psychology. Choices A, B, and C are incorrect because cognitive psychologists focus on mental processes, counseling psychologists on helping individuals with personal and interpersonal issues, and developmental psychologists on human growth and development, respectively, which are not directly related to studying attitudes towards traditional sex roles influenced by societal factors.
