ATI RN

Psychological Exam

1. 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.

2. What are some common methods used to study genetic influences on behavior?

A. Genetic influences are studied only through twin studies.
B. Common methods include twin studies, adoption studies, and gene mapping.
C. Genetic influences on behavior are only studied through family history.
D. Genetic influences on behavior are not well understood.

Correct answer: B

Rationale: Common methods used to study genetic influences on behavior include twin studies, adoption studies, and gene mapping. Twin studies help to compare the similarities between identical and fraternal twins to estimate the heritability of a trait. Adoption studies look at the similarities between adopted children and their biological and adoptive parents to determine genetic influences. Gene mapping involves identifying specific genes associated with certain behaviors. Choices A, C, and D are incorrect because genetic influences on behavior are not solely studied through twin studies or family history, and while the understanding of genetic influences may vary, there are established methods to study them.

3. What is the significance of early intervention in preventing mental disorders?

A. Early intervention has no significant impact on preventing mental disorders.
B. Early intervention is critical in reducing the risk of developing mental disorders.
C. Early intervention can sometimes exacerbate mental disorders.
D. Early intervention is only effective in severe cases.

Correct answer: B

Rationale: Early intervention is crucial in preventing or mitigating the development of mental disorders by addressing issues before they fully develop. Choice A is incorrect because early intervention plays a significant role in preventing mental disorders. Choice C is incorrect as early intervention aims to improve mental health outcomes. Choice D is incorrect as early intervention is effective across various stages of mental health conditions, not just in severe cases.

4. Rita shows better control over her eating habits at 2.5 years than her brother Richard did at the same age. Why?

A. Girls are naturally smarter than boys.
B. Second-born children learn faster.
C. Girls have better fine motor skills.
D. Boys have better gross motor skills.

Correct answer: D

Rationale: The correct answer is D because boys typically develop gross motor skills, like running and jumping, more quickly than girls. This can explain why Richard may have had less control over his eating habits compared to Rita at the same age. Choices A, B, and C are incorrect because they do not address the specific developmental aspect related to eating habits control mentioned in the question.

5. William James, who was a pioneer in the development of functionalism, was most heavily influenced by?

A. Charles Darwin.
B. Sigmund Freud.
C. John Watson.
D. B.F. Skinner.

Correct answer: A

Rationale: William James was heavily influenced by Charles Darwin's theory of evolution, which shaped his functionalist views on psychology. This influence is evident in James's emphasis on adaptation, survival, and the functional purposes of behavior. Choice B, Sigmund Freud, is incorrect because Freud's psychoanalytic theory focused on unconscious processes and childhood experiences, which differ significantly from James's functionalism. Choice C, John Watson, is incorrect as Watson was a behaviorist who emphasized observable behavior and rejected mental processes, which contrasts with James's focus on mental processes. Choice D, B.F. Skinner, is also incorrect as Skinner was a behaviorist known for his work on operant conditioning, which is not directly aligned with James's functionalist perspective.
