ATI RN

Psychology 101 Exam 3 Test

1. How does genetic predisposition influence mental health?

A. Genetic predisposition guarantees the development of mental disorders.
B. Genetic predisposition plays a role but is not the sole determinant of mental health.
C. Genetic predisposition does not influence mental health.
D. Genetic predisposition determines mental health without exception.

Correct answer: B

Rationale: Genetic predisposition indeed plays a significant role in influencing mental health by increasing the risk of developing certain disorders. However, it is crucial to note that it is not the sole determinant. Mental health is also influenced by various environmental factors, lifestyle choices, and individual experiences. Option A is incorrect because genetic predisposition does not guarantee the development of mental disorders; it only predisposes individuals to a higher risk. Option C is incorrect as genetic predisposition does have an influence on mental health. Option D is incorrect because mental health is a complex interplay of genetic, environmental, and other factors.

2. What is the diathesis-stress model of psychopathology?

A. The idea that stress is the primary cause of psychopathology.
B. A model that focuses solely on genetic predispositions.
C. A theory that involves only environmental factors in the development of disorders.
D. A person must have both a vulnerability for a disorder and exposure to stressors to develop the disorder.

Correct answer: D

Rationale: The diathesis-stress model of psychopathology posits that individuals must have a vulnerability or predisposition to a disorder (diathesis) and be exposed to stressful environmental factors for the disorder to manifest. This model emphasizes the interaction between genetic or biological vulnerabilities (diathesis) and environmental stressors. Choice A is incorrect because the model does not suggest that stress is the sole cause of psychopathology. Choice B is incorrect as the model considers both genetic predispositions and environmental stressors. Choice C is incorrect because the diathesis-stress model acknowledges the role of both genetic and environmental factors in the development of disorders.

3. What role does genetic predisposition play in the development of mental disorders?

A. Genetic predisposition guarantees the development of mental disorders.
B. Genetic predisposition plays a significant role but is not the only factor in developing mental disorders.
C. Genetic predisposition is irrelevant in mental health.
D. Genetic predisposition can be completely overridden by environmental factors.

Correct answer: B

Rationale: Genetic predisposition plays a significant role in the development of mental disorders, interacting with environmental factors. While genetics can predispose individuals to certain mental disorders, it is not a guarantee that the disorders will develop. Environmental factors, such as lifestyle, upbringing, and traumatic experiences, also play a crucial role in the manifestation of mental health conditions. Choice C is incorrect as genetic predisposition does have relevance in mental health. Choice D is incorrect as genetic predisposition and environmental factors both contribute to the development of mental disorders, neither completely overriding the other.

4. What does incidence refer to?

A. How many new cases of a disorder occur during a given period of time
B. How many people have recovered from a disorder in a given period of time
C. The percentage of males and females who have a disorder
D. How many people in the population as a whole have a disorder

Correct answer: A

Rationale: The correct answer is A: 'How many new cases of a disorder occur during a given period of time.' Incidence specifically measures the rate of occurrence of new cases of a particular condition within a defined population and time frame. This distinguishes it from prevalence, which includes both new and existing cases. Choices B, C, and D are incorrect because they do not accurately define the term 'incidence.' Choice B refers to recovery, choice C mentions gender distribution, and choice D relates to the total population affected by a disorder, which are not reflective of the concept of incidence.

5. Where is the site of chemical communication in the brain?

A. Neuron
B. Synapse
C. Axon
D. Dendrite

Correct answer: B

Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.
