1. Which of the following statements is true?

A. Most behavioral disorders are determined exclusively by genes.
B. Genes play a role in most mental disorders.
C. Genes do not affect biochemical processes.
D. The genes that will be expressed in an individual are not affected by experience.

Correct answer: B

Rationale: The correct answer is B: 'Genes play a role in most mental disorders.' This statement is true as genes do play a significant role in the development of various mental disorders. Choice A is incorrect because most behavioral disorders are influenced by a combination of genetic, environmental, and other factors, not exclusively genes. Choice C is incorrect as genes do affect biochemical processes. Choice D is incorrect because the expression of genes in an individual can be influenced by experiences and environmental factors, a concept known as gene-environment interaction.

2. Which part of the superego develops from our experiences with rewards for proper behavior and tells us what we should do?

A. Conscience
B. Ego-ideal
C. Regressing back to the anal stage
D. Regressing back to the oral stage

Correct answer: B

Rationale: The correct answer is B, the Ego-ideal. The Ego-ideal is a subsystem of the superego that develops from experiences with rewards for proper behavior. It guides individuals on what they should do, setting standards and ideals for behavior. Choice A, Conscience, represents the part of the superego that focuses on what one should not do, based on experiences with punishment for improper behavior. Choices C and D, regressing back to the anal and oral stages respectively, are irrelevant to the development of the superego's components and are not related to experiences with rewards for proper behavior.

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. Which of the following statements is least likely to be made by a humanist?

A. Humans are unique.
B. The behavior of humans tends to be influenced by environmental circumstances.
C. Humans have a basic need to fulfill their potentials.
D. Research on animals has little relevance to understanding human behavior.

Correct answer: B

Rationale: The corrected question assesses the least likely statement made by a humanist. Choice B, 'The behavior of humans tends to be influenced by environmental circumstances,' is least likely to be made by a humanist. Humanists believe that human behavior is not simply dictated by environmental circumstances but is influenced by a combination of factors, including personal experiences, emotions, and conscious decisions. Choices A, C, and D are more aligned with humanist perspectives. Choice A acknowledges the uniqueness of humans, which is a common theme in humanistic psychology. Choice C reflects the humanistic belief that individuals strive to reach their full potential and self-actualization. Choice D contrasts with humanist views as humanists often consider research on animals to be relevant in understanding human behavior due to shared basic psychological processes.

5. What is the traditional cutoff in diagnosing intellectual disability?

A. IQ score below 80
B. IQ score below 70
C. IQ score below 60
D. IQ score below 50

Correct answer: B

Rationale: The traditional cutoff for diagnosing intellectual disability is an IQ score below 70. An IQ score below 70 is generally considered as the threshold for diagnosing intellectual disability. Choices A, C, and D are incorrect as they do not reflect the commonly accepted cutoff point for diagnosing intellectual disability.
