Exam 4 Psychology

1. How is pruning best defined?

A. The process of eliminating unused synapses
B. The process of synapse development
C. The connection between neurons
D. Fatty sheath that wraps around neurons and enables them to transmit information more rapidly

Correct answer: A

Rationale: Pruning is the process of eliminating unused synapses in the brain. This process helps the brain to become more efficient by strengthening important connections and eliminating unnecessary ones. Choice B is incorrect because pruning is about eliminating synapses, not developing them. Choice C is incorrect as it refers to the general concept of connections between neurons, not specifically about pruning. Choice D is incorrect as it describes the myelin sheath, which is responsible for rapid transmission of information along neurons, not pruning.

2. What is the traditional cutoff in diagnosing intellectual disability?

A. IQ score below 80
B. IQ score below 70
C. IQ score below 60
D. IQ score below 50

Correct answer: B

Rationale: The traditional cutoff for diagnosing intellectual disability is an IQ score below 70. An IQ score below 70 is generally considered as the threshold for diagnosing intellectual disability. Choices A, C, and D are incorrect as they do not reflect the commonly accepted cutoff point for diagnosing intellectual disability.

3. When examining heredity, mental disorders are almost always ________.

A. influenced by one particular gene.
B. influenced by multiple genes.
C. influenced by recessive genes.
D. not influenced by genes.

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.

4. What would a humanist most likely say about Manny's passivity?

A. Manny will find it difficult to change because he probably has deep-seated feelings of inferiority.
B. Manny can become more assertive once he begins to feel better about himself and recognizes that he has the ability to fulfill his potential.
C. Manny simply needs to take an assertiveness training class in which he can learn and practice assertive behaviors.
D. Manny should undergo analysis so that he can begin to resolve whatever unconscious conflict is at the root of his passivity.

Correct answer: B

Rationale: Humanists believe in the inherent goodness and potential of individuals. They would most likely say that Manny can become more assertive by improving his self-esteem and recognizing his abilities. Choice A is incorrect because humanists focus on self-actualization rather than deep-seated feelings of inferiority. Choice C is incorrect as it oversimplifies the issue by suggesting a training class can solve the problem without addressing underlying beliefs. Choice D is incorrect as it suggests a psychoanalytic approach, while humanists usually emphasize personal growth and self-improvement.

5. Which perspective or viewpoint focuses on intrapsychic conflicts as the cause of psychopathology?

A. Biological
B. Behavioral
C. Psychodynamic
D. Sociocultural

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.
