Psychology 101 Exam 3 Test

1. How do neurotransmitters affect behavior and mental processes?

A. Neurotransmitters have little effect on behavior.
B. Neurotransmitters are chemicals that influence mood, thought, and behavior.
C. Neurotransmitters have a minor role in mental health.
D. Neurotransmitters determine intelligence levels.

Correct answer: B

Rationale: Neurotransmitters are chemicals that influence mood, thought, and behavior, playing a significant role in mental health. Choice A is incorrect as neurotransmitters do have a notable effect on behavior. Choice C is incorrect as neurotransmitters have a major role in mental health. Choice D is incorrect as neurotransmitters do not solely determine intelligence levels.

2. How is binge-eating disorder different from bulimia?

A. Typically eat much smaller portions before purging the food.
B. Do not typically purge the food they eat.
C. Only purge their food after several binge sessions.
D. Often resort to anorexic methods to rid themselves of the food they have eaten.

Correct answer: B

Rationale: The correct answer is B because individuals with binge-eating disorder do not typically engage in purging behavior, unlike those with bulimia. Choice A is incorrect as individuals with binge-eating disorder do not purge the food they eat, so they do not eat smaller portions before doing so. Choice C is incorrect as they do not purge their food after several binge sessions. Choice D is incorrect as individuals with binge-eating disorder do not resort to anorexic methods to rid themselves of the food they have eaten.

3. In order to develop chicken pox, one must be exposed to the virus that causes chicken pox. Note, however, that not everyone who is exposed to the virus is affected. In other words, the virus is a ________

A. risk factor.
B. necessary cause.
C. sufficient cause.
D. contributory cause.

Correct answer: B

Rationale: The correct answer is B: 'necessary cause.' A necessary cause must be present for a disorder to occur. In the context of developing chicken pox, being exposed to the virus is a necessary condition for contracting the disease. Choices A, C, and D are incorrect. A 'risk factor' increases the probability of developing a disease but is not essential for its occurrence. A 'sufficient cause' can produce the outcome on its own, which is not the case with exposure to the chicken pox virus. A 'contributory cause' adds to other causes to produce an effect, but in this scenario, exposure to the virus is crucial by itself.

4. Oliver is studying motivation in chimpanzees. His roommate doesn't think that Oliver's research will produce much useful information about human motivation because he believes that information from animal studies will not provide meaningful information about human experiences. Oliver's roommate apparently has?

A. A humanistic perspective.
B. An evolutionary perspective.
C. A biological perspective.
D. A cognitive perspective.

Correct answer: A

Rationale: Oliver's roommate holds a humanistic perspective. This perspective emphasizes human uniqueness and may devalue information obtained from animal studies when studying human experiences. The humanistic perspective focuses on subjective experiences, free will, and personal growth, which aligns with his roommate's belief that animal studies won't provide meaningful information about human experiences. Choice B, an evolutionary perspective, would focus on the role of evolution in shaping behavior, not directly related to the roommate's view. Choices C and D, biological and cognitive perspectives respectively, do not directly address the roommate's skepticism toward using animal studies to understand human motivation.

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.
