Exam 4 Psychology 101

1. What does incidence refer to?

A. How many new cases of a disorder occur during a given period of time
B. How many people have recovered from a disorder in a given period of time
C. The percentage of males and females who have a disorder
D. How many people in the population as a whole have a disorder

Correct answer: A

Rationale: The correct answer is A: 'How many new cases of a disorder occur during a given period of time.' Incidence specifically measures the rate of occurrence of new cases of a particular condition within a defined population and time frame. This distinguishes it from prevalence, which includes both new and existing cases. Choices B, C, and D are incorrect because they do not accurately define the term 'incidence.' Choice B refers to recovery, choice C mentions gender distribution, and choice D relates to the total population affected by a disorder, which are not reflective of the concept of incidence.

2. What role do hormones play in mental health and behavior?

A. Hormones only affect physical processes, not mental health.
B. Hormones play a critical role in regulating mood, behavior, and mental health.
C. Hormones have no effect on behavior.
D. Hormones are only involved in reproductive processes.

Correct answer: B

Rationale: Hormones play a critical role in regulating mood, behavior, and mental health, influencing everything from stress response to emotional stability. Choice A is incorrect because hormones have a significant impact on mental health in addition to physical processes. Choice C is incorrect as hormones do have a notable effect on behavior. Choice D is incorrect as hormones have broad functions beyond just reproductive processes.

3. How does the concept of neural plasticity relate to recovery from brain injuries?

A. Neural plasticity means the brain cannot recover from injuries.
B. Neural plasticity allows the brain to recover and reorganize after injuries.
C. Neural plasticity refers to the brain's inability to change after injury.
D. Neural plasticity is a myth.

Correct answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

4. During which period of psychosexual development does a child become preoccupied with the development of skills and activities?

A. Genital
B. Phallic
C. Latency
D. Pubertal

Correct answer: C

Rationale: The correct answer is C, Latency. In the Latency stage of psychosexual development, which occurs from around age 6 to puberty, children are focused on developing skills and engaging in activities rather than exploring sexuality. This period is characterized by the suppression of sexual impulses and the emphasis on social and intellectual pursuits. Choice A, Genital, refers to the final stage of psychosexual development in Freud's theory where individuals reach sexual maturity. Choice B, Phallic, pertains to the stage where children become aware of anatomical differences between boys and girls and develop unconscious sexual desires for the opposite-sex parent. Choice D, Pubertal, is not a recognized stage in Freud's psychosexual development theory.

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.
