EPPP EXAM NEWEST 2026 ACTUAL EXAM TEST BANK
EXAMINATION FOR PROFESSIONAL PRACTICE IN PSYCHOLOGY
|350 REAL EXAM QUESTIONS AND CORRECT DETAILED
ANSWERS WITH RATIONALES ALREADY GRADED A+ | EPPP
EXAM PREP 2026 (BRAND NEW!!)
INSTRUCTIONS: This comprehensive test bank covers all eight content domains of the
EPPP (Examination for Professional Practice in Psychology) as outlined by the ASPPB.
Domains include: Biological Bases of Behavior (10%), Cognitive-Affective Bases of
Behavior (13%), Social and Cultural Bases of Behavior (12%), Growth and Lifespan
Development (12%), Assessment and Diagnosis (16%), Treatment, Intervention,
Prevention, and Supervision (16%), Research Methods and Statistics (8%), and
Ethical, Legal, and Professional Issues (13%). Each question includes the correct
answer and a detailed rationale to enhance understanding and exam preparation.
SECTION 1: BIOLOGICAL BASES OF BEHAVIOR (Qs 1–50)
Q1: Which ion primarily drives the depolarizing phase of the neuronal action
potential?
A) K⁺ (Potassium)
B) Na⁺ (Sodium)
C) Ca²⁺ (Calcium)
D) Cl⁻ (Chloride)
Answer: B) Na⁺ (Sodium)
Rationale: During depolarization, voltage-gated sodium channels open, allowing
Na⁺ ions to rapidly flow into the neuron, making the inside more positive. K⁺
efflux drives repolarization, Ca²⁺ is involved in neurotransmitter release,
and Cl⁻ influx typically causes hyperpolarization.
Q2: Which of the following neurotransmitters is most directly implicated in
the pathophysiology of Parkinson's disease?
1
,A) Serotonin
B) Norepinephrine
C) Dopamine
D) Acetylcholine
Answer: C) Dopamine
Rationale: Parkinson's disease is characterized by the progressive
degeneration of dopaminergic neurons in the substantia nigra pars compacta,
leading to dopamine depletion in the basal ganglia. This results in the motor
symptoms of tremor, rigidity, bradykinesia, and postural instability.
Q3: The primary inhibitory neurotransmitter in the central nervous system is:
A) Glutamate
B) GABA
C) Glycine
D) Substance P
Answer: B) GABA
Rationale: GABA (gamma-aminobutyric acid) is the primary inhibitory
neurotransmitter in the CNS, reducing neuronal excitability by increasing Cl⁻
influx. Glutamate is the primary excitatory neurotransmitter. Glycine is
inhibitory in the spinal cord. Substance P is involved in pain transmission.
Q4: Which of the following brain structures is most critical for the
consolidation of new explicit (declarative) memories?
A) Amygdala
B) Hippocampus
C) Cerebellum
D) Basal ganglia
2
,Answer: B) Hippocampus
Rationale: The hippocampus is essential for the consolidation of explicit
(declarative) memories, including episodic and semantic memories. The amygdala
is involved in emotional memory, the cerebellum in procedural memory, and the
basal ganglia in habit learning.
Q5: The "fight or flight" response is primarily mediated by which branch of
the autonomic nervous system?
A) Parasympathetic nervous system
B) Sympathetic nervous system
C) Somatic nervous system
D) Enteric nervous system
Answer: B) Sympathetic nervous system
Rationale: The sympathetic nervous system activates the "fight or flight"
response, preparing the body for action by increasing heart rate, dilating
pupils, and releasing adrenaline. The parasympathetic nervous system mediates
"rest and digest" functions.
Q6: Which of the following is TRUE regarding the blood-brain barrier (BBB)?
A) It allows all substances to freely enter the brain
B) It is composed of tightly packed endothelial cells that restrict the passage
of most molecules
C) It is absent in the hypothalamus
D) It only allows lipid-insoluble molecules to pass
Answer: B) It is composed of tightly packed endothelial cells that restrict the
passage of most molecules
3
, Rationale: The BBB is formed by tightly joined endothelial cells in brain
capillaries that restrict the passage of most substances, protecting the brain
from toxins and pathogens. Lipid-soluble molecules can cross more readily, and
the BBB is present throughout the brain.
Q7: In classical conditioning, which structure is most associated with the
acquisition of conditioned fear responses?
A) Hippocampus
B) Amygdala
C) Prefrontal cortex
D) Thalamus
Answer: B) Amygdala
Rationale: The amygdala, particularly the lateral and central nuclei, is
critical for the acquisition and expression of conditioned fear responses.
It receives sensory information and coordinates autonomic and behavioral
fear responses.
Q8: Which of the following neurotransmitters is primarily associated with the
reward pathway and is targeted by most drugs of abuse?
A) Serotonin
B) Norepinephrine
C) Dopamine
D) Acetylcholine
Answer: C) Dopamine
Rationale: Dopamine is the primary neurotransmitter in the mesolimbic reward
pathway, projecting from the ventral tegmental area to the nucleus accumbens.
