Psychology 2301 Exam 1

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. In order for one to have a recessive trait (e.g., having red hair), the person must receive?

A. At least one copy of a recessive gene from a parent
B. Two copies of a recessive gene, one from each parent
C. At least one copy of a recessive gene and at least one copy of a dominant gene
D. At least two copies of a recessive gene from one parent

Correct answer: B

Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.

3. Cortisol is a hormone that ________

A. is released by the hypothalamus and travels to the pituitary gland, causing it to respond.
B. the pituitary gland releases to stimulate the adrenal gland.
C. the adrenal gland produces that mobilizes the body to deal with stress.
D. reduces the reuptake of the monoamine neurotransmitters.

Correct answer: C

Rationale: The correct answer is C. Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. It helps regulate metabolism, reduce inflammation, and assist in memory formulation. Choice A is incorrect as cortisol is not released by the hypothalamus and does not travel to the pituitary gland. Choice B is incorrect as cortisol is not released by the pituitary gland but acts on it to regulate hormone production. Choice D is incorrect as cortisol does not reduce the reuptake of monoamine neurotransmitters.

4. When interviewing a new member of the psychology department for the university newspaper, the faculty member states, 'many times, people are unaware of the unconscious motivations that drive their overt actions.' This faculty member's views are most similar to the views held by?

A. F. Skinner.
B. Carl Rogers.
C. Wilhelm Wundt.
D. Sigmund Freud

Correct answer: D

Rationale: The correct answer is D, Sigmund Freud. Freud's psychoanalytic theory emphasized the influence of unconscious motivations on behavior. This aligns with the faculty member's statement about people being unaware of the unconscious drives behind their actions. Choice A, F. Skinner, is incorrect because Skinner focused on observable behavior and reinforcement. Choice B, Carl Rogers, is incorrect as Rogers is associated with humanistic psychology and self-actualization, not unconscious motivations. Choice C, Wilhelm Wundt, is also incorrect as he is known for establishing the first psychology laboratory and structuralism, not unconscious motivations.

5. William James, who was a pioneer in the development of functionalism, was most heavily influenced by?

A. Charles Darwin.
B. Sigmund Freud.
C. John Watson.
D. B.F. Skinner.

Correct answer: A

Rationale: William James was heavily influenced by Charles Darwin's theory of evolution, which shaped his functionalist views on psychology. This influence is evident in James's emphasis on adaptation, survival, and the functional purposes of behavior. Choice B, Sigmund Freud, is incorrect because Freud's psychoanalytic theory focused on unconscious processes and childhood experiences, which differ significantly from James's functionalism. Choice C, John Watson, is incorrect as Watson was a behaviorist who emphasized observable behavior and rejected mental processes, which contrasts with James's focus on mental processes. Choice D, B.F. Skinner, is also incorrect as Skinner was a behaviorist known for his work on operant conditioning, which is not directly aligned with James's functionalist perspective.
