Quiz: Etiology of Mental Disorders — 22 questions

1. Which combination of influences is included in the bio-psycho-social-spiritual perspective on mental disorders?

A. Biological, economic, genetic, and environmental influences

B. Social, developmental, medical, and instinctual influences

C. Biological, psychological, social, and spiritual influences

D. Psychological, neurological, cultural, and behavioral influences

Answer: (C)

Explanation

This perspective organizes possible causes across biological, psychological, social, and spiritual domains. A purely biological account is incomplete because it does not include the psychological, social, and spiritual influences identified by the framework.

2. What cause was historically associated with disordered behavior before broader modern frameworks organized its possible influences?

A. A social cause

B. A spiritual cause

C. An instinctual cause

D. A genetic cause

Answer: (B)

Explanation

Historically, disordered behavior was often explained as having a spiritual cause. This historical explanation differs from the broader modern framework, which considers several interacting domains.

3. How can conditioning change a normal fear after a person encounters a black widow spider?

A. It can turn the response into a physical reaction without changing the person’s behavior.

B. It can replace the fear with a cautious concern limited to the original spider.

C. It can make unfamiliar places seem safe while increasing attention to bodily sensations.

D. It can expand the fear into an irrational fear of spiders or places where they may be found.

Answer: (D)

Explanation

Conditioning can generalize an initially normal fear into an overblown fear of spiders or locations associated with them. A cautious concern limited to the original encounter does not describe this expansion into phobic fear.

4. Why can completely avoiding places where spiders might be found worsen a spider-related fear?

A. Avoidance can lower physical arousal while making the feared situation easier to approach.

B. Avoidance can convert an irrational fear into a normal protective response over time.

C. Avoidance can reinforce the behavior by preventing the person from confronting the feared situation.

D. Avoidance can eliminate the fear response by removing every reminder of the feared animal.

Answer: (C)

Explanation

Avoiding feared places can reinforce avoidance because the person does not confront or deal with the feared situation. Removing reminders may feel relieving, but it does not address the reinforcing cycle described here.

5. What distinguishes a phobia from a normal fear?

A. A phobia is a brief physical response that occurs without emotional distress.

B. A phobia is an irrational fear that has become overblown.

C. A phobia is a normal fear directed toward a genuinely dangerous object.

D. A phobia is a learned preference for avoiding unfamiliar situations.

Answer: (B)

Explanation

A phobia develops when a normal fear becomes irrational and overblown. A normal fear may be appropriate to danger, whereas the defining feature of a phobia is disproportionate fear.

6. How can the body’s response to intense fear lead to fainting?

A. Compensation can increase heart rate and breathing until oxygen levels become excessive.

B. Compensation can maintain high blood pressure until the person becomes physically exhausted.

C. Compensation can lower heart rate and blood pressure after they rise during fight-or-flight.

D. Compensation can stop breathing while keeping blood pressure elevated during fear.

Answer: (C)

Explanation

Fight-or-flight can raise heart rate, breathing, and blood pressure, followed by compensation that lowers heart rate and blood pressure enough to cause fainting. Continued elevation of these measures does not describe the compensatory mechanism linked to fainting.

7. How can intensified emotional responses affect a person’s behavior around feared situations?

A. They can weaken physiological reactions and increase visits to unfamiliar places.

B. They can separate emotional distress from bodily reactions while preserving normal routines.

C. They can reduce bodily arousal and make prolonged outdoor activity more likely.

D. They can intensify physiological reactions and encourage avoidance of spider-related areas.

Answer: (D)

Explanation

Strong emotional responses can amplify physiological reactions and lead a person to avoid spider-related areas or remain inside much of the time. Increased activity in unfamiliar places would move in the opposite direction from the described avoidance effect.

8. What characterizes agoraphobia?

A. Fear of social judgment that commonly leads a person to avoid conversations

B. Fear of bodily sensations that commonly leads a person to monitor the heart

C. Fear of spiders that commonly leads a person to avoid webs and wooded areas

D. Fear of unfamiliar places that commonly leads a person to stay home or inside

Answer: (D)

Explanation

Agoraphobia involves fear of the unknown or unfamiliar places and often results in staying home or indoors. Fear specifically centered on spiders describes arachnophobia rather than agoraphobia.

9. What can influence the intensity of a person’s response to a feared situation?

A. The number of people present and the distance from the nearest familiar location

B. The amount of information available about the feared object during adulthood

C. Past events and the age at which they occurred, especially during early development

D. The person’s current preference for indoor activities and familiar routines

Answer: (C)

Explanation

Past events and the developmental age when they occurred can shape how intensely a person responds, with early experiences being especially influential. Current preferences or available information are not the specific developmental factors identified here.

10. Which description best defines a diathesis in the diathesis-stress model?

A. A predisposition toward developing a particular disorder

B. An environmental pressure that produces immediate distress

C. A treatment that reduces symptoms of a disorder

D. A behavioral response that follows psychological stress

Answer: (A)

Explanation

A diathesis is an underlying vulnerability, such as genetic risk or family history, for a particular disorder. Environmental or situational pressure is classified as stress rather than diathesis.

11. How does the diathesis-stress model explain the development of a disorder?

A. A disorder develops when environmental pressure is absent

B. A predisposition combined with stress can produce a disorder

C. Stress eliminates the effects of an inherited vulnerability

D. A genetic predisposition by itself constitutes a disorder

Answer: (B)

Explanation

The model represents disorder development as the interaction of diathesis and stress, expressed as $\text{diathesis} + \text{stress} = \text{disorder}$. A vulnerability alone is not equivalent to the combined effect of vulnerability and stress.

12. What is a neurotransmitter?

A. A specialized brain cell that sends and receives neural signals

B. A biochemical element that communicates chemically between neurons

C. A psychological disorder caused by disrupted brain chemistry

D. A medication that changes the activity of neural receptors

Answer: (B)

Explanation

A neurotransmitter is a biochemical messenger that communicates chemically from one neuron to another. A neuron is the cell involved in sending or receiving the signal, not the chemical messenger itself.

13. Which set contains the five main neurotransmitters emphasized in relation to disorders?

A. Glutamate, GABA, serotonin, norepinephrine, and dopamine

B. Serotonin, norepinephrine, adrenaline, cortisol, and glutamate

C. GABA, melatonin, dopamine, endorphins, and oxytocin

D. Glutamate, insulin, serotonin, acetylcholine, and cortisol

Answer: (A)

Explanation

The emphasized group consists of glutamate, GABA, serotonin, norepinephrine, and dopamine. The other sets combine neurotransmitters with hormones or chemicals outside the specified group.

14. Why can GABA have an anxiety-reducing effect?

A. It raises impulsivity by lowering serotonin activity

B. It excites neurons and increases action-related behavior

C. It controls cardiovascular responses by increasing respiration

D. It reduces activity between neurons and produces a calming effect

Answer: (D)

Explanation

GABA reduces activity between neurons, which contributes to a calming effect that can lessen anxiety, particularly generalized anxiety. The description of exciting neurons applies to glutamate rather than GABA.

15. Which pattern is associated with very low serotonin levels?

A. Insomnia, poor concentration, and low physical energy

B. Anxiety, depression, and panic attacks linked to cardiovascular changes

C. Calmness, reduced reactivity, and improved emotional control

D. Impulsivity, aggression, and excessive sexual behavior

Answer: (D)

Explanation

Very low serotonin is associated with impulsivity, overreactions, aggression, suicide, impulsive overeating, and excessive sexual behavior. Insomnia and low energy are associated with low glutamate, while anxiety and panic attacks can be linked to low norepinephrine.

16. What is the intended action of an agonist drug on a neurotransmitter?

A. It increases the neurotransmitter's activity

B. It replaces the neurotransmitter with a different chemical

C. It decreases the neurotransmitter's activity

D. It blocks communication between every nearby neuron

Answer: (A)

Explanation

An agonist is intended to increase the activity of a neurotransmitter. Decreasing or blocking neurotransmitter impact describes an antagonist rather than an agonist.

17. A medication is designed to reduce the impact of a particular neurotransmitter. What type of medication is it?

A. A diathesis that creates vulnerability to a disorder

B. A stressor that produces environmental pressure

C. An antagonist that decreases or blocks neurotransmitter impact

D. An agonist that increases neurotransmitter activity

Answer: (C)

Explanation

An antagonist decreases or blocks the impact of a neurotransmitter, matching the medication's intended action. An agonist has the opposite purpose: increasing neurotransmitter activity.

18. What does learned helplessness describe?

A. Believing that one’s actions cannot improve a difficult situation

B. Changing behavior after receiving approval from a social group

C. Learning a response by observing another person’s behavior

D. Developing confidence after successfully solving repeated problems

Answer: (A)

Explanation

Learned helplessness involves the belief that personal action cannot improve the situation, which can contribute to despair and negative thinking. Modeling is the related but different process of learning by observing others.

19. Which theory emphasizes observational learning through modeling, particularly in children?

A. John Bowlby’s Attachment Theory

B. Aaron Beck’s Cognitive Theory

C. Albert Bandura’s Social Learning Theory

D. B. F. Skinner’s Operant Conditioning Theory

Answer: (C)

Explanation

Albert Bandura’s Social Learning Theory explains how observed or modeled behavior can strongly influence behavior, especially in children. Operant conditioning focuses on consequences rather than observational learning as its defining mechanism.

20. Which situation represents a factor that can contribute to mental illness?

A. Maintaining a stable and nurturing family environment

B. Experiencing severe psychological trauma during childhood

C. Receiving consistent emotional support from family members

D. Developing effective skills for relating to other people

Answer: (B)

Explanation

Severe childhood psychological trauma is identified as a factor that may contribute to mental illness. Supportive relationships, effective social skills, and a nurturing family environment are not listed as contributing risk factors in this context.

21. What does equifinality mean in the study of behavior or disorders?

A. Several different causes can lead to the same behavior or disorder

B. Similar behaviors arise when people receive identical social treatment

C. One underlying cause produces a single predictable behavioral outcome

D. A disorder develops through biological inheritance without environmental influence

Answer: (A)

Explanation

Equifinality refers to the possibility that several different causes can lead to one behavior or disorder. It does not mean that one cause produces one fixed outcome or that identical treatment is required.

22. A researcher explains a disorder using inherited vulnerability, conditioning, emotional reactions, and social support; which causal domains are being applied?

A. Medical, economic, educational, and geographic domains

B. Biological, behavioral, emotional-cognitive, and social domains

C. Cultural, nutritional, technological, and historical domains

D. Genetic, occupational, developmental, and legal domains

Answer: (B)

Explanation

The major causal domains include biological inherited potential, behavioral conditioning and fight-or-flight responses, emotional and cognitive processes, and social reactions or support. The other groupings do not match the established domains used to explain behavior or disorders.
