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. What is object-relations theory?

• A. It is the theory that focuses on observable behaviors only.
• B. It is a newer psychodynamic theory focusing on how individuals interact with others and their internalized relationships.
• C. It is the theory that emphasizes the importance of cognitive processes in shaping behavior.
• D. It is a cognitive-behavioral theory focused on changing maladaptive thought patterns.

Correct answer: B

Rationale: Object-relations theory is a psychodynamic theory that focuses on how individuals interact with others and their internalized relationships. Choice A is incorrect because object-relations theory goes beyond observable behaviors to explore internalized relationships. Choice C is incorrect because object-relations theory does not primarily emphasize cognitive processes. Choice D is incorrect because object-relations theory is not a cognitive-behavioral theory focused on changing thought patterns.

3. What is extinction and how might it be used in treating a disorder?

• A. Extinction strengthens the conditioned response by continuously pairing the conditioned stimulus with the unconditioned stimulus.
• B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
• C. Extinction is ineffective and is not used in treating disorders.
• D. Extinction is the process of intensifying the conditioned response by pairing the conditioned stimulus with a stronger unconditioned stimulus.

Correct answer: B

Rationale: The correct answer is B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This helps in reducing or eliminating undesired behaviors. Choice A is incorrect because extinction does not strengthen the conditioned response but weakens it. Choice C is also incorrect as extinction is a valid technique used in treating disorders by reducing unwanted behaviors. Choice D is incorrect as extinction does not involve intensifying the conditioned response but rather diminishing it.

4. Which of the following is a common effect of persistent discrimination?

• A. Increased happiness
• B. Greater intelligence and wisdom
• C. Cardiovascular reactivity
• D. Increased consciousness

Correct answer: C

Rationale: The correct answer is C: Cardiovascular reactivity. Persistent discrimination can have negative impacts on an individual's physical health, leading to increased cardiovascular reactivity. This can manifest as higher blood pressure, heart rate, and overall stress on the cardiovascular system. Choices A, B, and D are incorrect because persistent discrimination typically does not result in increased happiness, greater intelligence and wisdom, or increased consciousness. Instead, it often leads to detrimental effects on mental and physical health.

5. What impact do parenting styles have on child development?

• A. Authoritarian parenting leads to positive developmental outcomes.
• B. Permissive parenting is associated with positive developmental outcomes.
• C. Neglectful parenting is associated with positive developmental outcomes.
• D. All parenting styles produce similar developmental outcomes.

Correct answer: B

Rationale: Permissive parenting is associated with positive developmental outcomes because it involves warmth and a lack of strict control. Authoritarian parenting, as mentioned in choice A, is characterized by strict rules and harsh discipline, which may not lead to the best developmental outcomes. Neglectful parenting, as in choice C, involves a lack of responsiveness and support, which can have detrimental effects on a child's development. Choice D is incorrect because different parenting styles can have varying impacts on child development.
