Psychology 2301 Exam 1

1. A predisposition toward developing a disorder is termed a ________.

A. diathesis
B. comorbidity
C. genotype
D. phenotype

Correct answer: A

Rationale: A diathesis is indeed the correct term for a predisposition toward developing a disorder. A diathesis refers to an underlying vulnerability or predisposition to a particular condition. Choice B, 'comorbidity,' refers to the presence of two or more disorders in the same individual. Choice C, 'genotype,' relates to an individual's genetic makeup. Choice D, 'phenotype,' refers to the observable characteristics of an organism resulting from the interaction of its genotype with the environment. Therefore, A is the most appropriate term for describing a predisposition toward developing a disorder.

2. 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.

3. What major departure did Freud's position have from prevailing viewpoints around the early 1900s?

A. Viewed abnormal behavior as resulting from biological causes.
B. Viewed people as not fully aware of the forces that control their behavior.
C. Proposed the existence of free will.
D. Emphasized environmental forces on behavior.

Correct answer: B

Rationale: Freud's major departure from prevailing viewpoints around the early 1900s was that he viewed people as not fully aware of the forces that control their behavior. This is reflected in his emphasis on unconscious forces influencing behavior. Choice A is incorrect as Freud focused on psychological rather than solely biological causes. Choice C is incorrect as Freud's theory did not emphasize free will but rather unconscious drives. Choice D is incorrect as Freud emphasized internal psychological forces over external environmental factors.

4. Which characteristics are associated with adults fixated in the anal stage?

A. Orderliness, obstinacy, or messiness
B. Fixated in the oral stage
C. Dissolves the electra complex
D. Triggers penis envy, which then dissolves the female oedipus complex

Correct answer: A

Rationale: The correct answer is A: 'Orderliness, obstinacy, or messiness.' According to Freud's psychosexual theory, fixation in the anal stage can lead to these characteristics in adulthood. Choice B is incorrect as fixation in the oral stage is associated with issues related to dependency and aggression. Choice C is incorrect as it refers to the Electra complex, which is not related to the anal stage fixation. Choice D is incorrect as it refers to penis envy and the female Oedipus complex, which are not directly related to characteristics of adults fixated in the anal stage.

5. 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.
