The site of chemical communication in the brain is the ________.
- A. neuron
- B. synapse
- C. axon
- D. dendrite
Correct Answer: B
Rationale: The synapse is the correct answer. It is the site where communication between neurons occurs through the release and reception of neurotransmitters. Choice A, neuron, is incorrect as it is the cell itself rather than a specific site of communication. Choice C, axon, is also incorrect as it is a part of the neuron that transmits signals away from the cell body. Choice D, dendrite, is not the correct answer either, as dendrites receive signals from other neurons but do not release neurotransmitters for communication.

How does the diathesis-stress model explain the onset of mental disorders?
- A. Stress alone is sufficient to cause mental disorders.
- B. Both genetic vulnerability and environmental stress are needed to trigger a disorder.
- C. Only genetic factors cause mental disorders.
- D. Environmental stressors alone can cause mental disorders.
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.
Why is it difficult to determine the nature of the relationship between divorce and the psychological functioning of family members?
- A. Cause and effect cannot be determined as preexisting behavioral abnormalities in either the parents or the children may make divorce more likely.
- B. The findings have been too inconsistent to draw any conclusions.
- C. While the effects of divorce are negative on children, the effects on the spouses are generally positive.
- D. Due to modern acceptance of divorce, there has been an ongoing decrease in the negative effects of divorce.
Correct Answer: A
Rationale: The correct answer is A because it highlights a crucial factor that makes it challenging to establish a clear cause and effect relationship between divorce and the psychological functioning of family members. Preexisting behavioral abnormalities in either the parents or the children may influence both the likelihood of divorce and the psychological functioning of family members. Choice B is incorrect as it generalizes the findings without specifying the key issue of preexisting conditions. Choice C is incorrect as it oversimplifies the effects of divorce on family members. Choice D is incorrect as it presents a broad statement without addressing the complexities involved in determining the effects of divorce.
Cross-cultural research on stress demonstrates that ________.
- A. Depression is a common response to life challenges in all countries studied.
- B. Stress rarely leads to any evidence of illness in non-Western cultures.
- C. Responses to stress vary cross-culturally.
- D. Culture-specific reactions are not seen to respond to alterations in the environment.
Correct Answer: C
Rationale: Cross-cultural research on stress demonstrates that responses to stress vary cross-culturally. Choice A is incorrect because depression being a common response in all countries studied is not supported by cross-cultural research findings. Choice B is incorrect as it generalizes that stress rarely leads to illness in non-Western cultures, which is not universally true. Choice D is incorrect as culture-specific reactions can indeed respond to alterations in the environment, as observed in various cross-cultural studies.
A lack of social skills, poor school performance, and moodiness have all been associated with which of the following parenting styles?
- A. Authoritarian
- B. Permissive/indulgent
- C. Authoritative
- D. Neglectful/uninvolved
Correct Answer: D
Rationale: The correct answer is D, Neglectful/uninvolved. This parenting style is associated with a lack of social skills, poor school performance, and moodiness due to the lack of parental involvement and emotional support. Authoritarian parenting (choice A) is characterized by strict rules and high demands, not necessarily linked to these issues. Permissive/indulgent parenting (choice B) involves few rules and high responsiveness, which may not directly lead to these problems. Authoritative parenting (choice C) combines high demands with emotional support and is actually linked to positive outcomes such as good school performance and social skills.
What is the relationship between socioeconomic status and the prevalence of abnormal behavior?
- A. Socioeconomic status does not affect the prevalence of abnormal behavior.
- B. There is a positive correlation between low socioeconomic status and a higher prevalence of abnormal behavior.
- C. Higher socioeconomic status is associated with a lower prevalence of abnormal behavior.
- D. Socioeconomic status and the prevalence of abnormal behavior are unrelated.
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.
