Psychology 2301 Exam 1
1. ______________ are conditions that increase the probability of a disorder but are neither necessary nor sufficient to cause it.
- A. Risk factors
- B. Contributory causes
- C. Sufficient causes
- D. Protective factors
Correct answer: B
Rationale: The correct term for conditions that increase the probability of a disorder but are neither necessary nor sufficient to cause it is 'Contributory causes.' Risk factors (Choice A) are conditions that increase the likelihood of a negative outcome but do not imply causation. Sufficient causes (Choice C) are conditions that guarantee the occurrence of a disorder by themselves. Protective factors (Choice D) decrease the likelihood of a disorder rather than increasing it.
2. a researcher found that there is a negative relationship between perceived parental perfectionism and life satisfaction. what does this mean?
- A. Respondents who reported higher levels of perceived parental perfectionism are more likely to report higher levels of life satisfaction
- B. Respondents who reported higher levels of perceived parental perfectionism are more likely to report lower levels of life satisfaction
- C. Perceived parental perfectionism causes a decline in life satisfaction
- D. Any of the above is correct
Correct answer: B
Rationale: A negative relationship means that as one variable increases, the other decreases, so higher perceived parental perfectionism is associated with lower life satisfaction.
3. 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.
4. One of Freud's major contributions to current perspectives of mental disorders is ________.
- A. the concept of the Oedipal complex.
- B. the concept of the unconscious and how it can affect behavior.
- C. the concept of the Electra complex.
- D. the understanding of the three structures of personality.
Correct answer: B
Rationale: Freud's major contribution to current perspectives of mental disorders is the concept of the unconscious and its influence on behavior. While the Oedipal complex (Choice A) and Electra complex (Choice C) are important psychoanalytic concepts introduced by Freud, they are more focused on childhood psychosexual development rather than mental disorders. The understanding of the three structures of personality (Choice D) refers to Freud's id, ego, and superego model, which is essential in psychoanalytic theory but not specifically related to mental disorders.
5. How is pruning best defined?
- A. The process of eliminating unused synapses
- B. The process of synapse development
- C. The connection between neurons
- D. Fatty sheath that wraps around neurons and enables them to transmit information more rapidly
Correct answer: A
Rationale: Pruning is the process of eliminating unused synapses in the brain. This process helps the brain to become more efficient by strengthening important connections and eliminating unnecessary ones. Choice B is incorrect because pruning is about eliminating synapses, not developing them. Choice C is incorrect as it refers to the general concept of connections between neurons, not specifically about pruning. Choice D is incorrect as it describes the myelin sheath, which is responsible for rapid transmission of information along neurons, not pruning.
