What neurotransmitter was first believed to be the cause of schizophrenia?
- A. GABA
- B. Serotonin
- C. Epinephrine
- D. Dopamine
Correct Answer: D
Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.

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.
What term refers to the mental processes involved in acquiring knowledge?
- A. Cognition.
- B. Pedagogy.
- C. Empiricism.
- D. Introspection.
Correct Answer: A
Rationale: The correct answer is A, cognition. Cognition encompasses mental processes like thinking, remembering, and problem-solving, all crucial in acquiring knowledge.

Introspection (choice D) involves examining one's own conscious thoughts and feelings, not specifically focused on acquiring knowledge.
Elliot became widowed after nearly 40 years of marriage. He has convinced himself that no one will ever love him again. His irrational thinking has caused him to suffer from depression, and he rarely leaves his house. What perspective might best explain his behavior?
- A. Psychodynamic
- B. Behavioral
- C. Biological
- D. Cognitive
Correct Answer: D
Rationale: The cognitive perspective might best explain Elliot's irrational thinking and resulting depression. In this case, Elliot's belief that he will never be loved again is a cognitive distortion, leading to depressive symptoms and social withdrawal. The psychodynamic perspective primarily focuses on unconscious processes and unresolved conflicts from the past, which do not directly address Elliot's current cognitive distortions. The behavioral perspective would focus on observable behaviors and how they are reinforced, which is not the central issue in this scenario. The biological perspective would examine the role of genetics, brain chemistry, and other physiological factors, which are not the primary cause of Elliot's behavior in this context.
In an experiment, the investigators manipulate variables to learn how one affects another.?
- A. A data-collection method in which participants respond to questions
- B. The entire group that is of interest to a researcher
- C. A detailed description of a single culture or context
- D. A study that tests a causal hypothesis
Correct Answer: D
Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.
Unlike those with autism spectrum disorder, those with reactive attachment disorder have a history of:
- A. Schizoid personality disorder
- B. Autism spectrum disorder
- C. Reactive attachment disorder
- D. Disinhibited social engagement disorder
Correct Answer: C
Rationale: The correct answer is C: Reactive attachment disorder. Individuals with reactive attachment disorder have a history of severe social neglect, which distinguishes it from autism spectrum disorder. Choice A, Schizoid personality disorder, is incorrect as it is not typically associated with the history described in reactive attachment disorder. Choice B, Autism spectrum disorder, is incorrect because individuals with autism spectrum disorder do not necessarily have a history of severe social neglect. Choice D, Disinhibited social engagement disorder, is also incorrect as it is a separate attachment disorder characterized by indiscriminate social behavior, not necessarily a history of neglect.
