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. A male college student begins feeling sad and lonely. Although still able to go to classes and work at his job, he finds himself feeling down much of the time and worrying about what is happening to him. Which part of the definition of abnormality applies to his situation?

• A. Personal distress
• B. Cultural factors
• C. Impaired functioning
• D. Violation of societal norms

Correct answer: A

Rationale: The correct answer is A: Personal distress. In this scenario, the student is experiencing personal distress as he feels sad and lonely, despite being able to function in his daily life. Personal distress is a key criterion for determining abnormality as it signifies significant emotional discomfort. Choices B, C, and D are incorrect as cultural factors, impaired functioning, and violation of societal norms are not the primary factors highlighted in the student's situation.

3. Which neurotransmitter is reduced in both the manic and depressive phases of bipolar disorder?

• A. Acetylcholine
• B. Dopamine
• C. Norepinephrine
• D. Serotonin

Correct answer: D

Rationale: The correct answer is D, Serotonin. Serotonin levels are reduced during both the manic and depressive phases of bipolar disorder. Acetylcholine (choice A) is not typically linked to bipolar disorder. Dopamine (choice B) and norepinephrine (choice C) are more commonly associated with conditions like schizophrenia and depression, respectively, rather than bipolar disorder. Therefore, they are not the neurotransmitters reduced in both manic and depressive phases of bipolar disorder.

4. Rita shows better control over her eating habits at 2.5 years than her brother Richard did at the same age. Why?

• A. Girls are naturally smarter than boys.
• B. Second-born children learn faster.
• C. Girls have better fine motor skills.
• D. Boys have better gross motor skills.

Correct answer: D

Rationale: The correct answer is D because boys typically develop gross motor skills, like running and jumping, more quickly than girls. This can explain why Richard may have had less control over his eating habits compared to Rita at the same age. Choices A, B, and C are incorrect because they do not address the specific developmental aspect related to eating habits control mentioned in the question.

5. A group of psychologists is conducting research to determine whether people eat more when they are in the presence of environmental stimuli that increase anxiety, such as loud noises or flashing lights. These scientists most likely follow?

• A. The behavioral perspective.
• B. The psychodynamic perspective.
• C. The humanistic perspective.
• D. The functionalist perspective.

Correct answer: A

Rationale: The correct answer is A, the behavioral perspective. This perspective focuses on how environmental stimuli influence behavior, making it suitable for studying how anxiety-inducing stimuli affect eating behavior. The psychodynamic perspective (choice B) would focus more on unconscious processes and early life experiences. The humanistic perspective (choice C) emphasizes personal growth and self-actualization. The functionalist perspective (choice D) is more related to the study of the purpose of behavior and mental processes in adapting to the environment.
