1. 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.

2. Which school of psychology is associated with understanding the purpose of behavior?

A. Functionalism.
B. Behaviorism.
C. Neodynamism.
D. Psychoanalysis.

Correct answer: A

Rationale: The correct answer is A, Functionalism. Functionalism, founded by William James, emphasizes understanding the purpose and adaptive function of behavior. This school of psychology focuses on how mental processes help individuals adapt to their environment. Choice B, Behaviorism, is incorrect as behaviorism emphasizes observable behaviors rather than the purpose behind them. Choice C, Neodynamism, is not a recognized school of psychology. Choice D, Psychoanalysis, founded by Sigmund Freud, focuses on unconscious processes and early childhood experiences, not specifically on the purpose of behavior.

3. Studies on the cultural differences in parental tolerance of under- or over-controlled behavior suggest that ________.

A. These different styles can produce different rates of problem behaviors in different cultures.
B. Parental styles make no difference in rates of different behavior problems; they seem to be primarily genetic.
C. Parental styles make no difference in rates of different behavior problems; they seem to be independent of culture.
D. All cultures feel the same about bringing their children for treatment, regardless of the type of behavior problem.

Correct answer: A

Rationale: Studies on the cultural differences in parental tolerance of under- or over-controlled behavior suggest that these different styles can produce different rates of problem behaviors in different cultures. This is because cultural norms and expectations influence how parental tolerance and responses to behavior are shaped. Choice B is incorrect because parental styles do play a role in behavior problems, influenced by cultural factors. Choice C is incorrect as parental styles can vary across cultures and impact behavior problems differently. Choice D is incorrect because cultural attitudes towards seeking treatment for behavior problems can vary significantly.

Catatonia is a symptom seen in some cases of schizophrenia, characterized by motor abnormalities such as peculiar hand and limb movements or adopting unusual postures for extended periods. Choice B, Loose association, refers to a thought disorder where ideas shift from one subject to another in an unrelated way. Choice C, Disorganized speech, is characterized by incoherent or incomprehensible speech patterns. Choice D, Blunted affect, describes a reduction in the intensity of emotional expression.

A. Occurs every time when one is in a certain situation
B. Occurs most of the time when one is in a specific situation

School phobia in children is often associated with separation anxiety disorder, leading to unexpected and intense fear or anxiety about attending school. Choices A and B are incorrect because school phobia does not necessarily occur every time or most of the time when in a specific situation; it is more about the unexpected fear related to attending school. Choice D is also incorrect because school phobia is characterized by an unexpected and overwhelming fear of school, not an expected or anticipated reaction.
