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. Which of the following is a common effect of persistent discrimination?
- A. Increased happiness
- B. Greater intelligence and wisdom
- C. Cardiovascular reactivity
- D. Increased consciousness
Correct answer: C
Rationale: The correct answer is C: Cardiovascular reactivity. Persistent discrimination can have negative impacts on an individual's physical health, leading to increased cardiovascular reactivity. This can manifest as higher blood pressure, heart rate, and overall stress on the cardiovascular system. Choices A, B, and D are incorrect because persistent discrimination typically does not result in increased happiness, greater intelligence and wisdom, or increased consciousness. Instead, it often leads to detrimental effects on mental and physical health.
3. 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.
4. With which of the following statements would a behaviorist agree?
- A. Conscious experiences can be studied in an objective, precise way.
- B. In order to understand behavior, one must understand the motives behind the behavior.
- C. Behavior can only be explained in terms of phenomenology, that is, an individual's interpretation of experience.
- D. Psychology should be the science of behavior that can be observed by others.
Correct answer: D
Rationale: The correct answer is D. Behaviorists argue that psychology should focus on observable behavior that can be studied objectively. Choice A is incorrect because behaviorists do not typically focus on conscious experiences, as they are not directly observable. Choice B is incorrect because behaviorists emphasize that behavior can be understood without delving into internal motives. Choice C is incorrect as behaviorists do not exclusively explain behavior through an individual's interpretation of experience; they focus on observable actions and reactions.
5. 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.
