COUC 546 Exam 1 V1 | COUC 546 Psychopathology | Actual Q&A with
Rationale (COUC546 Exam 1) | Liberty University
1. Which component of a psychological disorder involves a breakdown in cognitive,
emotional, or behavioral functioning?
A. Psychological dysfunction
B. Statistical infrequency
C. Personal distress
D. Atypical response
Answer: A
Explanation: Psychological dysfunction refers to a disruption in the expected functioning
of an individual’s mental processes. It is one of the three criteria, alongside distress and
impairment, used to define a psychological disorder. This concept helps clinicians identify
when behavior deviates from a healthy functional baseline.
2. The ‘scientist-practitioner’ model in psychology suggests that counselors should:
A. Focus exclusively on laboratory research
B. Avoid using standardized diagnostic tools
C. Prioritize clinical intuition over data
D. Evaluate their own assessments and treatments
Answer: D
Explanation: The scientist-practitioner model emphasizes that clinical practice should be
informed by scientific research and empirical evidence. Practitioners are expected to utilize
evidence-based treatments and measure the effectiveness of their interventions. This
approach ensures that client care is both ethical and grounded in current psychological
science.
3. What is the term for the number of people in a population who have a specific disorder at
any given time?
A. Prevalence
B. Incidence
C. Occurrence
D. Prognosis
Answer: A
,Explanation: Prevalence refers to the total number of active cases in a population during a
specific period. This differs from incidence, which tracks only the number of new cases
diagnosed within a timeframe. Understanding prevalence is essential for public health
planning and resource allocation in mental health.
4. Which historical figure is associated with the ‘humoral theory’ of psychological disorders?
A. Hippocrates
B. B.F. Skinner
C. Philippe Pinel
D. Sigmund Freud
Answer: A
Explanation: Hippocrates suggested that mental illness was caused by imbalances in four
bodily fluids, or humors: blood, black bile, yellow bile, and phlegm. This theory represented
a shift toward a biological understanding of mental health, moving away from supernatural
explanations. It laid the early groundwork for modern physiological approaches to
psychopathology.
5. In the diathesis-stress model, ‘diathesis’ refers to:
A. An inherited genetic vulnerability
B. An environmental trigger
C. A specific stressful life event
D. The clinical diagnosis itself
Answer: A
Explanation: The diathesis-stress model posits that individuals inherit certain
vulnerabilities (diathesis) that may be activated by environmental stressors. Neither the
genetic predisposition nor the stressor alone is typically sufficient to cause a disorder. This
model highlights the complex interaction between nature and nurture in the development
of mental illness.
6. Which neurotransmitter is primarily associated with the regulation of mood, behavior, and
thought processes?
A. Glutamate
B. GABA
C. Dopamine
D. Serotonin
Answer: D
, Explanation: Serotonin plays a critical role in regulating a wide range of functions,
including mood, sleep, and appetite. Low levels of serotonin are frequently linked to
depression and anxiety disorders. Many common pharmacological treatments, such as
SSRIs, aim to increase the availability of this neurotransmitter in the brain.
7. The primary function of Gamma-aminobutyric acid (GABA) is to:
A. Excite the central nervous system
B. Facilitate muscle movement
C. Regulate the sleep-wake cycle
D. Inhibit or reduce neural activity
Answer: D
Explanation: GABA is the primary inhibitory neurotransmitter in the mammalian central
nervous system. It acts to calm neural activity and reduce the experience of anxiety and
arousal. Medications like benzodiazepines work by enhancing the effects of GABA to
produce a sedative effect.
8. According to the multidimensional integrative approach, psychopathology is caused by:
A. Biological factors only
B. Psychological factors only
C. Multiple interacting influences
D. Social and cultural factors only
Answer: C
Explanation: The multidimensional integrative approach suggests that no single factor
causes a psychological disorder. Instead, biological, psychological, and social factors
interact in complex ways to influence mental health. This holistic view is the standard for
modern clinical assessment and diagnosis.
9. Which part of the brain is most closely associated with the processing of emotions, such as
fear and aggression?
A. Basal ganglia
B. Amygdala
C. Occipital lobe
D. Thalamus
Answer: B
Explanation: The amygdala is a key structure within the limbic system that processes
emotional responses. It is particularly active during the experience of fear and the
