Psychology 101 Exam 3 Test

1. 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, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.

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. What is the sequence in which growth starts at the center of the body and moves toward the extremities?

A. Cephalocaudal pattern
B. Proximodistal pattern
C. Cephamodistal pattern
D. Gene-environment correlation

Correct answer: B

Rationale: The correct answer is B: Proximodistal pattern. This pattern describes growth starting at the center of the body and moving towards the extremities. Choice A, Cephalocaudal pattern, refers to growth starting from the head and moving downwards, which is not the sequence described in the question. Choice D, Gene-environment correlation, does not relate to the sequential pattern of growth described in the question, making it incorrect.

4. According to John Watson, behavior is governed primarily by?

A. Heredity.
B. Personal motives.
C. The environment.
D. Unconscious desires.

Correct answer: C

Rationale: According to John Watson, behavior is primarily governed by environmental factors. Watson was a behaviorist who emphasized the influence of the environment on behavior. He believed that behavior is shaped by external stimuli and experiences, rather than internal factors like heredity or unconscious desires. Therefore, choices A, B, and D are incorrect as they do not align with Watson's perspective on behaviorism.

5. What would a humanist most likely say about Manny's passivity?

A. Manny will find it difficult to change because he probably has deep-seated feelings of inferiority.
B. Manny can become more assertive once he begins to feel better about himself and recognizes that he has the ability to fulfill his potential.
C. Manny simply needs to take an assertiveness training class in which he can learn and practice assertive behaviors.
D. Manny should undergo analysis so that he can begin to resolve whatever unconscious conflict is at the root of his passivity.

Correct answer: B

Rationale: Humanists believe in the inherent goodness and potential of individuals. They would most likely say that Manny can become more assertive by improving his self-esteem and recognizing his abilities. Choice A is incorrect because humanists focus on self-actualization rather than deep-seated feelings of inferiority. Choice C is incorrect as it oversimplifies the issue by suggesting a training class can solve the problem without addressing underlying beliefs. Choice D is incorrect as it suggests a psychoanalytic approach, while humanists usually emphasize personal growth and self-improvement.
