Psychology 101 Final Exam

Correct Answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not 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 extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

Correct Answer: A

Rationale: The selection of a theoretical perspective matters because it determines how data is interpreted and influences the treatment approaches that are considered appropriate. Choice B is incorrect because different perspectives may lead to different interpretations and treatment strategies. Choice C is incorrect because different theoretical perspectives can result in varied treatment outcomes. Choice D is incorrect because theoretical perspectives play a crucial role in both academic research and clinical practice.

Correct Answer: B

Rationale: Genetic predisposition plays a significant role in the development of mental disorders, interacting with environmental factors. While genetics can predispose individuals to certain mental disorders, it is not a guarantee that the disorders will develop. Environmental factors, such as lifestyle, upbringing, and traumatic experiences, also play a crucial role in the manifestation of mental health conditions. Choice C is incorrect as genetic predisposition does have relevance in mental health. Choice D is incorrect as genetic predisposition and environmental factors both contribute to the development of mental disorders, neither completely overriding the other.

Correct Answer: B

Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.

Correct Answer: B

Rationale: According to Freud's theory of psychosexual development, if a person does not resolve a particular stage successfully, they become fixated at that stage. This fixation can lead to behavior patterns characteristic of that stage in later life. In this context, 'defended' is incorrect because it does not align with Freud's theory of fixation. 'Repressed' is not the correct choice as it refers to the unconscious suppression of thoughts or desires. 'Displaced' involves redirecting emotions from their original source to a substitute target, which is not the concept Freud associated with unresolved psychosexual stages.
