ATI RN

Psychology 101 Exam 3 Test

1. What role do hormones play in mental health and behavior?

A. Hormones only affect physical processes, not mental health.
B. Hormones play a critical role in regulating mood, behavior, and mental health.
C. Hormones have no effect on behavior.
D. Hormones are only involved in reproductive processes.

Correct answer: B

Rationale: Hormones play a critical role in regulating mood, behavior, and mental health, influencing everything from stress response to emotional stability. Choice A is incorrect because hormones have a significant impact on mental health in addition to physical processes. Choice C is incorrect as hormones do have a notable effect on behavior. Choice D is incorrect as hormones have broad functions beyond just reproductive processes.

2. What are genes made of?

A. Trisomes
B. Chromosomes
C. DNA
D. Proteins

Correct answer: C

Rationale: Genes are made of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of organisms. While chromosomes contain genes, they are not what genes themselves are made of. Proteins are involved in gene expression and regulation, but they are not the primary material genes consist of. Trisomes is an incorrect term in this context and does not relate to the composition of genes.

3. How does psychoanalytic theory attempt to explain personality, motivation, and mental disorders?

A. Studying observable behavior.
B. Analyzing conscious experience into its basic elements.
C. Focusing on unconscious determinants of behavior.
D. Studying the function or purpose of consciousness.

Correct answer: C

Rationale: Psychoanalytic theory focuses on the unconscious determinants of behavior to explain personality, motivation, and mental disorders. This approach suggests that hidden forces in the unconscious mind influence our thoughts, feelings, and behaviors, shaping our overall psychological makeup. Choice A is incorrect because psychoanalytic theory delves beyond observable behavior. Choice B is incorrect as psychoanalytic theory goes deeper than analyzing conscious experience alone. Choice D is incorrect as psychoanalytic theory is more concerned with unconscious processes rather than the function or purpose of consciousness.

4. Why is it particularly useful to study identical twins who were raised in different environments?

A. Differences in brain function can be easily identified.
B. Concordance rates tend to be higher.
C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

5. During which period of psychosexual development does a child become preoccupied with the development of skills and activities?

A. Genital
B. Phallic
C. Latency
D. Pubertal

Correct answer: C

Rationale: The correct answer is C, Latency. In the Latency stage of psychosexual development, which occurs from around age 6 to puberty, children are focused on developing skills and engaging in activities rather than exploring sexuality. This period is characterized by the suppression of sexual impulses and the emphasis on social and intellectual pursuits. Choice A, Genital, refers to the final stage of psychosexual development in Freud's theory where individuals reach sexual maturity. Choice B, Phallic, pertains to the stage where children become aware of anatomical differences between boys and girls and develop unconscious sexual desires for the opposite-sex parent. Choice D, Pubertal, is not a recognized stage in Freud's psychosexual development theory.
