Psychology 101 Final Exam

1. Why does the selection of a theoretical perspective of mental disorders matter?

A. Because it determines how data is interpreted, and influences treatment approaches.
B. It matters because different perspectives offer different insights into the causes and treatments of mental disorders.
C. The selection of a theoretical perspective is not important as all perspectives lead to the same treatment outcomes.
D. Theoretical perspectives are only relevant for academic research, not for clinical practice.

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.

2. Down syndrome is caused by ________.

A. a chemical imbalance.
B. a gene on the X chromosome.
C. possessing an extra X chromosome.
D. possessing an extra chromosome in chromosome 21.

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.

3. According to the diathesis-stress model, having a predisposition towards mental illness...

A. Means that a person will surely develop a mental disorder in the future
B. Does not affect the chances of developing a mental disorder
C. Increases the chance that a person would have a mental disorder
D. None of the above

Correct answer: C

Rationale: According to the diathesis-stress model, having a predisposition towards mental illness increases the risk but does not guarantee the development of a mental disorder. Choice A is incorrect as the model does not imply certainty. Choice B is incorrect as having a predisposition does affect the chances. Choice D is incorrect as the model does have an impact on the likelihood of developing a mental disorder.

4. Distinguish between necessary, sufficient, and contributory causes of abnormal behavior.

A. Necessary causes are required for a disorder to develop but do not guarantee it.
B. Sufficient causes guarantee a disorder will develop, but they are not required.
C. Contributory causes increase the likelihood of a disorder but are neither necessary nor sufficient.
D. Contributory causes are conditions that guarantee the occurrence of a disorder.

Correct answer: A

Rationale: In understanding abnormal behavior, it is crucial to differentiate between necessary, sufficient, and contributory causes. Necessary causes are those that are required for a disorder to develop, meaning that without them, the disorder would not occur. However, their presence does not guarantee the occurrence of the disorder. Sufficient causes, on the other hand, are those that alone can guarantee the development of a disorder, but they are not the only factors that can lead to it. Contributory causes are factors that increase the likelihood of a disorder but are not essential on their own nor do they guarantee the disorder. Therefore, choice A is the correct answer as it accurately describes the role of necessary causes in the development of abnormal behavior. Choices B, C, and D are incorrect as they misrepresent the definitions and roles of sufficient and contributory causes in causing abnormal behavior.

5. Michael, age 16, has recently gained a considerable amount of weight but has not grown any taller. His father experienced a similar pattern of growth when he was a teenager. Theorists who suggest that Michael’s growth pattern was inherited from his father emphasize the ________ side of the nature-nurture debate?

A. Nature
B. Nurture
C. Environmental
D. Experiential

Correct answer: A

Rationale: The correct answer is 'A: Nature.' In this scenario, the emphasis is on the genetic inheritance of the growth pattern from father to son, highlighting the role of nature in determining physical characteristics. Choice B, 'Nurture,' focuses on environmental influences, which are not the primary factor in this case. Choice C, 'Environmental,' is similar to 'Nurture' and does not address the genetic aspect mentioned. Choice D, 'Experiential,' pertains more to the learning and experiential aspects rather than genetic inheritance, making it an incorrect choice.
