PSYCHOLOGIST EPPP PRACTICE EXAMINATION FOR
PROFESSIONAL PRACTICE IN PSYCHOLOGY (EPPP)
PRACTICE QUESTIONS WITH CORRECT ANSWERS AND
RATIONALES
1. Which neurotransmitter is most directly associated with
neuromuscular transmission at the skeletal muscle junction?
A. Dopamine
B. Acetylcholine
C. Serotonin
D. Gamma-aminobutyric acid (GABA)
Correct Answer: B. Acetylcholine
Rationale: Acetylcholine is released by motor neurons at the
neuromuscular junction and binds to nicotinic receptors on skeletal
muscle fibers, initiating muscle contraction.
,2. Damage to the hippocampus is most likely to produce which deficit?
A. Impaired procedural learning
B. Difficulty forming new explicit memories
C. Loss of basic reflexes
D. Impaired visual acuity
Correct Answer: B. Difficulty forming new explicit memories
Rationale: The hippocampus is essential for consolidating new
declarative or explicit memories. Damage can cause anterograde
amnesia while leaving many procedural skills intact.
3. Which brain structure plays a central role in regulating hunger, thirst,
temperature, and endocrine activity?
A. Hypothalamus
B. Medulla
C. Occipital lobe
D. Caudate nucleus
,Correct Answer: A. Hypothalamus
Rationale: The hypothalamus regulates homeostasis, motivated
behaviors, autonomic processes, and endocrine functions through its
relationship with the pituitary gland.
4. The primary function of myelin is to:
A. Produce neurotransmitters
B. Slow electrical transmission
C. Increase the speed of neural conduction
D. Prevent synaptic communication
Correct Answer: C. Increase the speed of neural conduction
Rationale: Myelin insulates axons and permits saltatory conduction, in
which action potentials jump between nodes of Ranvier, increasing
transmission speed.
5. Which division of the autonomic nervous system is primarily
responsible for the “fight-or-flight” response?
, A. Somatic nervous system
B. Parasympathetic nervous system
C. Sympathetic nervous system
D. Central nervous system
Correct Answer: C. Sympathetic nervous system
Rationale: The sympathetic nervous system mobilizes the body during
stress by increasing heart rate, dilating airways, and redirecting blood
flow toward skeletal muscles.
6. A patient with Parkinson’s disease is most likely to show symptoms
associated with reduced activity in which neurotransmitter system?
A. Dopaminergic
B. Glutamatergic
C. Histaminergic
D. Oxytocinergic
