1. Which of the following statements is true?

• A. Most behavioral disorders are determined exclusively by genes.
• B. Genes play a role in most mental disorders.
• C. Genes do not affect biochemical processes.
• D. The genes that will be expressed in an individual are not affected by experience.

Correct answer: B

Rationale: The correct answer is B: 'Genes play a role in most mental disorders.' This statement is true as genes do play a significant role in the development of various mental disorders. Choice A is incorrect because most behavioral disorders are influenced by a combination of genetic, environmental, and other factors, not exclusively genes. Choice C is incorrect as genes do affect biochemical processes. Choice D is incorrect because the expression of genes in an individual can be influenced by experiences and environmental factors, a concept known as gene-environment interaction.

2. _______ memory stores information about facts, whereas _______ memory stores information about our personal experiences.

• A. Declarative, episodic
• B. Episodic, semantic
• C. Semantic, nondeclarative
• D. Semantic, episodic

Correct answer: D

Rationale: The correct answer is D: "Semantic, episodic." Semantic memory is responsible for storing factual information, such as concepts and general knowledge. Episodic memory, on the other hand, stores personal experiences and events. Choice A is incorrect because declarative memory is an umbrella term that includes both semantic and episodic memory, so it is not a direct contrast. Choice B is incorrect as it switches the definitions of episodic and semantic memory. Choice C is incorrect because nondeclarative memory refers to implicit or procedural memory, which is different from episodic memory.

3. 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.

4. 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.

5. 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.
