Psychology 2301 Exam 1
1. Neural plasticity is ________.
- A. the process by which neurotransmitters are broken down in the brain.
- B. the flexibility of the brain—existing neural circuits can change or new ones can be made.
- C. strong evidence of brain damage, leading to the development of a mental disorder.
- D. the best indicator of temperament and its effect on the personality development of a child.
Correct answer: B
Rationale: Neural plasticity refers to the brain's flexibility to change existing neural circuits or create new ones. Choice A is incorrect as it describes neurotransmitter breakdown, not neural plasticity. Choice C is incorrect because neural plasticity does not necessarily indicate brain damage leading to mental disorders. Choice D is incorrect because neural plasticity is not specifically related to temperament or personality development in children.
2. Normal human cells have ________.
- A. twenty-two chromosome pairs and one pair of sex chromosomes.
- B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
- C. twenty-one chromosome pairs and two trisomy chromosome pairs.
- D. twenty-three chromosome pairs.
Correct answer: A
Rationale: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.
3. Freud's view of mental disorders was that they were a result of ________.
- A. unresolved conflicts between the id, the ego, and the superego.
- B. genetic abnormalities that influence people's ability to cope with their environment.
- C. problematic tendencies we develop while dealing with our early interpersonal environments.
- D. learned maladaptive behaviors that were rewarded with attention.
Correct answer: A
Rationale: Freud believed that mental disorders were a result of unresolved conflicts between the id, ego, and superego. This concept is central to Freud's psychoanalytic theory, where conflicts between these three components of personality lead to psychological distress. Choice B is incorrect because Freud focused more on unconscious conflicts rather than genetic abnormalities. Choice C is incorrect as it refers to later psychodynamic theories rather than Freud's specific view. Choice D is incorrect as Freud's perspective does not emphasize learned behaviors as the primary cause of mental disorders.
4. Dr. Lee is studying pain perception using a functionalist perspective. It is most likely that Dr. Lee would suggest that we can only understand the conscious experience of pain?
- A. If all the component parts that make up the experience of pain are understood.
- B. By observing the outward expression of pain in response to different stimuli.
- C. If we first understand the role of pain in human survival and adaptation.
- D. If we understand the unconscious processes that initiate the sensation of pain.
Correct answer: C
Rationale: The functionalist perspective, as used by Dr. Lee, focuses on understanding the role of pain in human survival and adaptation. This perspective suggests that to fully comprehend pain perception, one must first grasp the significance of pain in terms of its adaptive functions and impact on behavior. Choices A, B, and D do not align with the functionalist perspective, as they do not emphasize the role of pain in human survival and adaptation.
5. Down syndrome is caused by ________
- A. a chemical imbalance.
- B. a gene on the X chromosome.
- C. possessing an extra X chromosome.
- D. possessing an extra chromosome in chromosome 21.
Correct answer: D
Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.
