Psychology 101 Exam 3 Test

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.

Correct Answer: A

Rationale: When a family member, especially a parent, suffers from serious depressive episodes, it can increase the risk of depression in other family members, including children. Therefore, in this situation, Dana is likely to be at risk for depression herself. Choice B is incorrect because experiencing a parent's depression does not necessarily lead to becoming a happy-go-lucky child; it can have serious emotional implications. Choice C is incorrect as there is no direct link between a parent's depression and a child acting in an aggressive, criminal manner. Choice D may seem plausible, but it is not the most likely outcome in this scenario.

Correct Answer: C

Rationale: The correct answer is C: 'Interaction between genetics and environment.' The genetic study of identical twins reared apart helps in understanding how both genetics and environment play a role in shaping an individual's traits and behaviors. This type of study allows researchers to tease apart the effects of genetic inheritance from those of environmental influences. Choices A, B, and D are incorrect because the study of identical twins reared apart specifically focuses on the interplay between genetics and environment, rather than solely on differences in brain function, genetic influence on behavior, or the role of environmental factors alone.

Correct Answer: C

Rationale: The correct answer is C: Psychodynamic. The psychodynamic perspective emphasizes the role of intrapsychic conflicts, often related to unconscious processes, in the development of psychopathology. This perspective, founded by Sigmund Freud, suggests that unresolved conflicts from early childhood experiences can manifest as mental health issues. Choice A, Biological, focuses on the physiological aspects of psychopathology, such as genetics and neurobiology. Choice B, Behavioral, looks at how behavior is learned and reinforced. Choice D, Sociocultural, considers the influence of social and cultural factors on mental health.

Correct Answer: B

Rationale: When examining heredity and mental disorders, it is important to note that these conditions are influenced by multiple genes working together. Mental disorders are complex traits that arise from the interplay of various genetic and environmental factors. Therefore, choice B, 'influenced by multiple genes,' is the correct answer. Choice A, 'influenced by one particular gene,' is incorrect because mental disorders typically do not result from the action of a single gene. Choice C, 'influenced by recessive genes,' is incorrect as it oversimplifies the genetic basis of mental disorders. Choice D, 'not influenced by genes,' is also incorrect as genes play a significant role in the development of mental disorders.
