Psychology 2301 Exam 1

Correct Answer: B

Rationale: Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This process helps in reducing or eliminating undesired behaviors or responses. Choice A is incorrect because extinction weakens the conditioned response by breaking the association between the conditioned stimulus and the unconditioned stimulus. Choice C is incorrect as extinction is a widely used technique in behavioral therapies for treating disorders. Choice D is incorrect as extinction aims to reduce the conditioned response, not intensify it.

Correct Answer: B

Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.

Correct Answer: B

Rationale: The correct answer is B because most behaviors are influenced by a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.

Correct Answer: A

Rationale: Overly aggressive behavior is often a major factor in a child's rejection by peers. Children who display overly aggressive behavior may intimidate or harm their peers, leading to social rejection. Being too intelligent or having a different socioeconomic background are not typically primary reasons for peer rejection. While empathy is important for healthy social interactions, a lack of empathy, on its own, is less likely to be a primary factor in peer rejection compared to overly aggressive behavior.

Correct Answer: C

Rationale: The correct answer is C, Projection. Projection is the defense mechanism where one attributes their own unacceptable feelings to others. In this scenario, Julia is projecting her feelings of guilt and shame onto her husband by accusing him of cheating. Sublimation (choice A) involves channeling unacceptable impulses into socially acceptable activities. Displacement (choice B) is redirecting emotions from the original source to a substitute target. Rationalization (choice D) is providing logical explanations to justify unacceptable behavior, which is not applicable in this context.
