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. Which of the following psychologists would be most likely to stress that each person has a drive to grow and fulfill his or her potential?

A. Sigmund Freud
B. F. Skinner
C. G. Stanley Hall
D. Abraham Maslow

Correct answer: D

Rationale: The correct answer is D, Abraham Maslow. He was a leading humanist psychologist who introduced the concept of the hierarchy of needs. Maslow emphasized the human drive for self-actualization, which involves fulfilling one's potential and striving for personal growth. Sigmund Freud (choice A) focused on psychoanalysis and the unconscious mind. B.F. Skinner (choice B) was a behaviorist who studied operant conditioning. G. Stanley Hall (choice C) was a pioneering psychologist in the field of child development.

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. While out for a walk, you come across a ferocious dog. You feel your heart beating faster and your palms begin to sweat. Which part of the peripheral nervous system is activated in this situation?

A. Autonomic
B. Sympathetic
C. Parasympathetic
D. Somatic

Correct answer: B

Rationale: The correct answer is B: Sympathetic. When encountering a stressful situation like a ferocious dog, the sympathetic nervous system is activated, leading to the 'fight or flight' response. This response triggers physiological changes like increased heart rate, sweating, and heightened alertness to prepare the body to deal with the perceived threat. The autonomic nervous system (Choice A) encompasses both the sympathetic and parasympathetic divisions, so it's a broader category. The parasympathetic nervous system (Choice C) is responsible for the body's 'rest and digest' functions, which are opposite to the physiological changes seen in a stress response. The somatic nervous system (Choice D) controls voluntary movements and sensory information, not the physiological responses seen in a stress reaction.

5. How does the biopsychosocial model differ from the biomedical model?

A. The biopsychosocial model focuses solely on the biological aspects of disease.
B. The biopsychosocial model includes biological, psychological, and social factors, whereas the biomedical model focuses on only biological factors.
C. The biopsychosocial model is outdated and has been replaced by the biomedical model.
D. The biopsychosocial model is identical to the biomedical model.

Correct answer: B

Rationale: The biopsychosocial model differs from the biomedical model by considering biological, psychological, and social factors in understanding health and illness. Choice A is incorrect because the biopsychosocial model does not solely focus on biological aspects. Choice C is incorrect as the biopsychosocial model is not outdated but rather offers a more comprehensive approach. Choice D is incorrect as the two models are distinct in their considerations of factors beyond biology.
