Psychological Exam

1. While the term psychology has existed since at least the early 1700s, psychology did not come to be considered a science until?

A. The 1750s.
B. The early 1800s.
C. The late 1800s.
D. The 1940s.

Correct answer: C

Rationale: Psychology became recognized as a science in the late 1800s, aligning with broader trends in scientific inquiry during that period. This marked the establishment of psychology as a distinct field of study based on empirical research and experimentation. Choices A, B, and D are incorrect because psychology's formal recognition as a science occurred later, specifically in the late 1800s.

2. What is the result when a single zygote separates into two parts, each developing into a separate individual?

A. Dizygotic twin
B. Monozygotic twin
C. Fraternal twin
D. Nonidentical twin

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

3. Unlike other types of anxiety disorders, this one is not triggered by anything specific, hence the name free-floating anxiety.

A. Social anxiety disorder
B. Generalized anxiety disorder
C. Panic disorder
D. Specific phobia

Correct answer: B

Rationale: The correct answer is B, Generalized anxiety disorder. Generalized anxiety disorder is characterized by persistent and excessive worry or anxiety that is not triggered by specific situations or objects, hence the term 'free-floating anxiety.' Social anxiety disorder (A) is characterized by fear and anxiety about social situations, panic disorder (C) involves recurrent unexpected panic attacks, and specific phobia (D) is an intense fear of a specific object or situation. Therefore, B is the most appropriate choice in the context of anxiety not being triggered by specific stimuli.

4. 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.

5. What is extinction and how might it be used in treating a disorder?

A. Extinction strengthens the conditioned response by continuously pairing the conditioned stimulus with the unconditioned stimulus.
B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
C. Extinction is ineffective and is not used in treating disorders.
D. Extinction is the process of intensifying the conditioned response by pairing the conditioned stimulus with a stronger unconditioned stimulus.

Correct answer: B

Rationale: The correct answer is B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This helps in reducing or eliminating undesired behaviors. Choice A is incorrect because extinction does not strengthen the conditioned response but weakens it. Choice C is also incorrect as extinction is a valid technique used in treating disorders by reducing unwanted behaviors. Choice D is incorrect as extinction does not involve intensifying the conditioned response but rather diminishing it.
