Psychology 101 Final Exam

1. Genes ________

A. determine how a person will behave.
B. cause people to develop mental disorders.
C. determine what characteristics a person will have.
D. determine the range of characteristics a person has.

Correct answer: D

Rationale: Genes determine the range of characteristics a person has. Choice A is incorrect because genes do not solely determine behavior, as behavior is influenced by a combination of genetic and environmental factors. Choice B is incorrect because while genes can contribute to the risk of developing mental disorders, they do not directly cause them. Choice C is incorrect as genes contribute to but do not solely determine all characteristics a person will have.

2. 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: Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. Therefore, choice C is the correct answer. Choices A and B are incorrect as they inaccurately describe the origin and function of cortisol. Choice D is also incorrect as it describes the action of a different type of substance, not cortisol.

3. Which psychosexual stage focuses on castration anxiety?

A. Genital
B. Oral
C. Anal
D. Phallic

Correct answer: D

Rationale: Castration anxiety is a concept from Freudian psychoanalytic theory that occurs during the Phallic stage. This stage occurs between 3 to 6 years of age and is when children experience conflicts related to the Oedipus complex (boys) and Electra complex (girls). During this stage, children may fear castration (in boys) or penis envy (in girls), which are crucial components of castration anxiety. Therefore, the correct answer is Phallic. The other options (A: Genital, B: Oral, C: Anal) are incorrect as they do not specifically involve castration anxiety but rather represent different stages in Freud's psychosexual development theory.

4. A predisposition toward developing a disorder is termed a ________.

A. diathesis
B. comorbidity
C. genotype
D. phenotype

Correct answer: A

Rationale: A diathesis is indeed the correct term for a predisposition toward developing a disorder. A diathesis refers to an underlying vulnerability or predisposition to a particular condition. Choice B, 'comorbidity,' refers to the presence of two or more disorders in the same individual. Choice C, 'genotype,' relates to an individual's genetic makeup. Choice D, 'phenotype,' refers to the observable characteristics of an organism resulting from the interaction of its genotype with the environment. Therefore, A is the most appropriate term for describing a predisposition toward developing a disorder.

5. According to the diathesis-stress model, having a predisposition towards mental illness...

A. Means that a person will surely develop a mental disorder in the future
B. Does not affect the chances of developing a mental disorder
C. Increases the chance that a person would have a mental disorder
D. None of the above

Correct answer: C

Rationale: According to the diathesis-stress model, having a predisposition towards mental illness increases the risk but does not guarantee the development of a mental disorder. Choice A is incorrect as the model does not imply certainty. Choice B is incorrect as having a predisposition does affect the chances. Choice D is incorrect as the model does have an impact on the likelihood of developing a mental disorder.
