Psychology 101 Final Exam

1. Why is it particularly useful to study identical twins who were raised in different environments?

A. Differences in brain function can be easily identified.
B. Concordance rates tend to be higher.
C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

2. 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.

3. A predisposition toward developing a disorder is termed a __________ .

A. Diathesis
B. Risk factor
C. Sufficient cause
D. Diathesis

Correct answer: A

Rationale: A predisposition toward developing a disorder is termed a diathesis. In this context, diathesis refers to an individual's susceptibility or predisposition to developing a disorder. A diathesis is not the same as a risk factor or a sufficient cause. A risk factor is a variable that increases the likelihood of developing a disorder but is not a predisposition itself. A sufficient cause is a factor that can produce the disorder on its own, not just a predisposition.

4. Franklin wakes up in a homeless shelter in another town. He doesn't know where he is or how he got there, and he's confused when people say he has been calling himself Anthony. This is most likely an episode of dissociative?

A. Amnesia
B. Dissociative fugue
C. Wandering
D. Flight of ideas

Correct answer: B

Rationale: The correct answer is B, Dissociative fugue. In the scenario described, Franklin experiencing memory loss, travel to another town, assuming a new identity (calling himself Anthony) aligns with dissociative fugue. Amnesia (Choice A) involves memory loss without the additional aspects of travel and assuming a new identity. Wandering (Choice C) is vague and does not encompass the complete set of symptoms described. Flight of ideas (Choice D) is a symptom of conditions like mania, not dissociative disorders.

5. Most behavioral disorders are determined primarily by ________.

A. genetics
B. upbringing
C. diet
D. environment

Correct answer: A

Rationale: Genetics play a significant role in the development of behavioral disorders. While upbringing, diet, and environment can also influence behavior, genetics are often the primary factor in determining behavioral disorders. Choice B (upbringing) can contribute to behavior but is not the sole determinant of behavioral disorders. Choice C (diet) can impact behavior but is not the primary factor in behavioral disorders. Choice D (environment) can also influence behavior, but genetics typically play a more significant role in determining behavioral disorders.
