1. According to Wilhelm Wundt, the focus of psychology was on the scientific study of?

• A. Observable behavior.
• B. Conscious experience.
• C. Unconscious motivation.
• D. The functions of behavior.

Correct answer: B

Rationale: Wilhelm Wundt's approach emphasized the study of conscious experience, marking a shift towards scientific methods in psychology. Choice A, observable behavior, is associated with behaviorism and not Wundt's structuralism. Choice C, unconscious motivation, is more aligned with Freud's psychoanalytic theory. Choice D, the functions of behavior, relates more to functionalism, which was developed by William James.

2. 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.

3. Which of the following statements about brain dysfunction and psychiatric disorders is correct?

• A. Identifiable brain damage is often the cause of psychiatric disorders.
• B. Brain damage may decrease the risk of developing a psychiatric condition.
• C. Changes in brain function appear to play a role in many psychiatric disorders.
• D. Brain development can be altered by experience, always leading to changes in the brain that decrease the risk of developing a psychiatric condition.

Correct answer: C

Rationale: The correct statement is C: 'Changes in brain function appear to play a role in many psychiatric disorders.' This statement is accurate as research suggests that alterations in brain function are associated with various psychiatric disorders. Option A is incorrect because while brain damage can contribute to some psychiatric conditions, it is not always the primary cause. Option B is incorrect as brain damage typically increases the risk of developing psychiatric disorders. Option D is incorrect because while brain development can be influenced by experiences, it does not always decrease the risk of psychiatric conditions.

4. How does the concept of neural plasticity relate to recovery from brain injuries?

• A. Neural plasticity means the brain cannot recover from injuries.
• B. Neural plasticity allows the brain to recover and reorganize after injuries.
• C. Neural plasticity refers to the brain's inability to change after injury.
• D. Neural plasticity is a myth.

Correct answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

5. In order to develop chicken pox, one must be exposed to the virus that causes chicken pox. Note, however, that not everyone who is exposed to the virus is affected. In other words, the virus is a ________

• A. risk factor.
• B. necessary cause.
• C. sufficient cause.
• D. contributory cause.

Correct answer: B

Rationale: The correct answer is B: 'necessary cause.' A necessary cause must be present for a disorder to occur. In the context of developing chicken pox, being exposed to the virus is a necessary condition for contracting the disease. Choices A, C, and D are incorrect. A 'risk factor' increases the probability of developing a disease but is not essential for its occurrence. A 'sufficient cause' can produce the outcome on its own, which is not the case with exposure to the chicken pox virus. A 'contributory cause' adds to other causes to produce an effect, but in this scenario, exposure to the virus is crucial by itself.
