Psychology 101 Exam 3 Test

1. When examining heredity, mental disorders are almost always ________

A. influenced by one particular gene.
B. influenced by multiple genes.
C. influenced by recessive genes.
D. not influenced by genes.

Correct answer: B

Rationale: When examining heredity, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.

2. The genetic influences that determine behavior may never be fully understood due to ________

A. the ease of researching to differentiate between the effects of the environment and the effects of genes.
B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
C. the tendency to rely on twin studies in genetic research.
D. our significant understanding of how genes impact brain chemistry.

Correct answer: B

Rationale: The correct answer is B because most behaviors are influenced by a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.

3. What are some common methods used to study genetic influences on behavior?

A. Genetic influences are studied only through twin studies.
B. Common methods include twin studies, adoption studies, and gene mapping.
C. Genetic influences on behavior are only studied through family history.
D. Genetic influences on behavior are not well understood.

Correct answer: B

Rationale: Common methods used to study genetic influences on behavior include twin studies, adoption studies, and gene mapping. Twin studies help to compare the similarities between identical and fraternal twins to estimate the heritability of a trait. Adoption studies look at the similarities between adopted children and their biological and adoptive parents to determine genetic influences. Gene mapping involves identifying specific genes associated with certain behaviors. Choices A, C, and D are incorrect because genetic influences on behavior are not solely studied through twin studies or family history, and while the understanding of genetic influences may vary, there are established methods to study them.

4. There is experimental evidence showing that consistently being discriminated against may cause a person to ________.

A. be happy.
B. be more conscious.
C. have cardiovascular reactivity.
D. have greater intelligence and wisdom.

Correct answer: C

Rationale: The correct answer is C: 'have cardiovascular reactivity.' Consistent discrimination can lead to increased cardiovascular reactivity, impacting heart health. Choice A ('be happy') is incorrect because discrimination typically causes distress and negative emotions. Choice B ('be more conscious') is not directly related to the impact of discrimination. Choice D ('have greater intelligence and wisdom') is also unrelated to the physiological response of cardiovascular reactivity caused by discrimination.

5. What are culture-bound syndromes?

A. Culture-bound syndromes are disorders that can be found in all cultures.
B. Culture-bound syndromes are disorders that are specific to certain cultural contexts.
C. Culture-bound syndromes are myths and do not exist.
D. Culture-bound syndromes are conditions seen only in psychiatric hospitals.

Correct answer: B

Rationale: Culture-bound syndromes are disorders that are specific to certain cultural contexts. These syndromes may not be recognized or understood outside of the specific cultural context where they originate. Choice A is incorrect because culture-bound syndromes are not universal and are tied to specific cultural beliefs and practices. Choice C is incorrect as culture-bound syndromes are recognized in the field of psychology and anthropology. Choice D is incorrect as culture-bound syndromes are not limited to psychiatric hospitals but can be observed in various cultural settings.
