Psychology 101 Exam 3 Test
1. How does stress impact brain function?
- A. Stress has no effect on brain function.
- B. Stress can lead to changes in brain structure and function.
- C. Stress can improve brain function.
- D. Stress has no long-term impact on brain function.
Correct answer: B
Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.
2. 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 and mental disorders, it is important to note that these conditions are influenced by multiple genes working together. Mental disorders are complex traits that arise from the interplay of various genetic and environmental factors. Therefore, choice B, 'influenced by multiple genes,' is the correct answer. Choice A, 'influenced by one particular gene,' is incorrect because mental disorders typically do not result from the action of a single gene. Choice C, 'influenced by recessive genes,' is incorrect as it oversimplifies the genetic basis of mental disorders. Choice D, 'not influenced by genes,' is also incorrect as genes play a significant role in the development of mental disorders.
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: 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.
4. What does the genetic study of identical twins reared apart help to clarify?
- A. Differences in brain function
- B. Genetic influence on behavior
- C. Interaction between genetics and environment
- D. The role of environmental factors alone
Correct answer: C
Rationale: The correct answer is C: 'Interaction between genetics and environment.' The genetic study of identical twins reared apart helps in understanding how both genetics and environment play a role in shaping an individual's traits and behaviors. This type of study allows researchers to tease apart the effects of genetic inheritance from those of environmental influences. Choices A, B, and D are incorrect because the study of identical twins reared apart specifically focuses on the interplay between genetics and environment, rather than solely on differences in brain function, genetic influence on behavior, or the role of environmental factors alone.
5. One important contribution of Freud's theory was that ________.
- A. he truly understood the role of women in society.
- B. he heavily utilized experimental evidence to support his theories.
- C. he applied the same principles to normal and abnormal behavior.
- D. he increased the focus on positive growth for individuals.
Correct answer: C
Rationale: Freud's important contribution was that he applied the same principles to both normal and abnormal behavior. This approach allowed for a comprehensive understanding of human behavior without creating a rigid distinction between normal and abnormal psychology. Choice A is incorrect because Freud's theory did not primarily focus on the role of women in society. Choice B is incorrect as Freud's theories were largely based on clinical observations and case studies rather than experimental evidence. Choice D is incorrect as Freud's theory emphasized the unconscious mind and conflicts rather than solely focusing on positive growth for individuals.
