Psychology 101 Final Exam

Correct Answer: B

Rationale: The correct answer is B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This helps in reducing or eliminating undesired behaviors. Choice A is incorrect because extinction does not strengthen the conditioned response but weakens it. Choice C is also incorrect as extinction is a valid technique used in treating disorders by reducing unwanted behaviors. Choice D is incorrect as extinction does not involve intensifying the conditioned response but rather diminishing it.

Correct Answer: B

Rationale: The correct answer is B, Id. In psychodynamic theory, the Id is the component driven by basic, primal instincts, seeking instant gratification without consideration for consequences. It operates on the pleasure principle, aiming to fulfill desires immediately. The Superego, on the other hand, represents the internalized moral standards and ideals, while the Ego mediates between the Id and Superego, balancing impulses with societal norms. The 'Ideal self' is a concept from humanistic psychology related to one's aspirations and goals, not a component in psychodynamic theory. Therefore, choices A, C, and D are incorrect.

Correct Answer: B

Rationale: The diathesis-stress model explains that the onset of mental disorders results from the interaction of genetic vulnerability (diathesis) and environmental stress. Choice A is incorrect because stress alone is not sufficient, according to the model. Choice C is incorrect as it oversimplifies by attributing mental disorders solely to genetic factors. Choice D is incorrect because the model emphasizes the joint contribution of genetic predisposition and environmental stress.

Correct Answer: B

Rationale: The correct answer is B. There is a positive correlation between low socioeconomic status and a higher prevalence of abnormal behavior. Individuals with lower socioeconomic status may face more stressors, reduced access to mental health resources, and other challenges that can contribute to a higher prevalence of abnormal behavior. Choice A is incorrect because socioeconomic status does affect the prevalence of abnormal behavior. Choice C is incorrect because higher socioeconomic status is not associated with a lower prevalence of abnormal behavior. Choice D is incorrect as there is a clear relationship between socioeconomic status and the prevalence of abnormal behavior.

Correct Answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not by a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an additional chromosome 21 disrupts the normal course of development and leads to the characteristics associated with Down syndrome.
