(2026) Q&A
1. Which subcortical brain structure is most directly implicated in the fear response
associated with anxiety disorders?
A) Hippocampus
B) Amygdala
C) Thalamus
D) Basal ganglia
Correct Answer: Amygdala
Rationale: The amygdala is central to processing emotional stimuli and triggering the
fight-or-flight response, and it is hyperactive in anxiety disorders. The hippocampus is
involved in memory consolidation, the thalamus relays sensory information, and the
basal ganglia are linked to motor control and habit formation. Understanding the
amygdala's role is essential for conceptualizing the neurobiology of anxiety.
2. The white matter of the brain is primarily composed of which of the following?
A) Cell bodies of neurons
B) Tracts of myelinated fibers connecting brain regions
C) Synaptic vesicles
D) Neurotransmitter storage sites
Correct Answer: Tracts of myelinated fibers connecting brain regions
Rationale: White matter consists of myelinated axons that facilitate communication
between different brain areas. Gray matter, by contrast, contains cell bodies and
,synaptic connections. This distinction is fundamental to neuroanatomical assessment in
psychopathology.
3. Which neurotransmitter is most associated with states of high arousal and is heavily
studied in anxiety and stress responses?
A) Serotonin
B) Dopamine
C) Norepinephrine
D) Acetylcholine
Correct Answer: Norepinephrine
Rationale: Norepinephrine produces states of high arousal and is implicated in
anxiety, stress responses, and mood regulation. Serotonin is more closely linked to mood
and obsessionality, dopamine to reward and psychosis, and acetylcholine to memory
and parasympathetic functions.
4. What does the abbreviation HPA stand for in the context of stress and
psychopathology?
A) Hypothalamic-Pituitary-Adrenal axis
B) Hippocampal-Prefrontal-Amygdala circuit
C) Hormonal-Protein-Activation system
D) Hypothalamic-Pineal-Autonomic pathway
Correct Answer: Hypothalamic-Pituitary-Adrenal axis
Rationale: The HPA axis is a major neuroendocrine system that controls reactions to
stress and regulates mood, emotion, and many body processes. Dysregulation of this
axis is implicated in depression, anxiety, and other psychiatric conditions.
, 5. Which statement best reflects the current understanding of what constitutes a
psychological disorder?
A) A single definition based solely on personal distress is sufficient
B) No single definition fully captures psychological disorders; they are best understood
through a combination of distress, dysfunction, and deviation from cultural norms
C) Norm violation alone is the best criterion
D) Disability and dysfunction alone are the best criteria
Correct Answer: No single definition fully captures psychological disorders; they are
best understood through a combination of distress, dysfunction, and deviation from
cultural norms
Rationale: The DSM-5-TR recognizes that no single component—distress,
dysfunction, deviance, or danger—alone can account for a psychological disorder. A
comprehensive understanding requires considering multiple factors in cultural context.
6. Which historical figure is credited with first proposing that psychological disorders
had natural, biological causes rather than supernatural origins?
A) Hippocrates
B) Plato
C) Aristotle
D) Galen
Correct Answer: Hippocrates
Rationale: Hippocrates, often called the father of medicine, proposed that mental
disorders had natural, biological causes. This laid the groundwork for the medical model
