Comprehensive 50-Question Original Actual Exam Set | 2026/2027
Introduction
This 2026/2027 comprehensive 50-question actual exam set provides original questions covering the Biological
Basis of Behavior and Sensation/Perception, Cognition, Learning, and Memory, Developmental and Social
Psychology, and Psychological Disorders and Treatment. The content is designed to reinforce official PSY 120
course objectives for actual exam readiness and academic success by strengthening understanding of brain-
behavior relationships, sensory processing, learning principles, memory systems, developmental change, social
influence, mental disorders, and evidence-based treatments. Each item includes Verified Questions with concise
rationales grounded in introductory psychology sources such as Myers and Ciccarelli, current APA guidance, and
evidence-based psychological research standards.
Domain: Biological Basis of Behavior and Sensation/Perception
1. Which brain structure is most directly involved in processing fear and emotional salience?
A. Amygdala
B. Cerebellum
C. Medulla
D. Corpus callosum
Correct Answer: A
Rationale: The amygdala is a limbic structure central to threat detection, fear conditioning, and emotional
significance.
2. Which part of the nervous system activates the fight-or-flight response?
A. Parasympathetic nervous system
B. Sympathetic nervous system
C. Somatic sensory system
D. Enteric nervous system only
Correct Answer: B
Rationale: The sympathetic branch mobilizes the body for action by increasing heart rate, respiration, and
energy availability.
3. Which neurotransmitter is most strongly associated with reward pathways and movement
regulation?
A. Acetylcholine only
B. Endorphin only
C. Dopamine
D. Histamine only
Correct Answer: C
Rationale: Dopamine contributes to reward, motivation, reinforcement learning, and motor control
circuits.

, 4. Damage to Broca’s area would most likely impair which function?
A. Color vision
B. Balance reflexes
C. Pain detection in the skin
D. Speech production
Correct Answer: D
Rationale: Broca’s area in the left frontal region is important for fluent speech production and language
expression.
5. Which lobe of the cerebral cortex contains the primary visual cortex?
A. Occipital lobe
B. Temporal lobe
C. Parietal lobe
D. Frontal lobe
Correct Answer: A
Rationale: The occipital lobe processes visual input arriving from the eyes through thalamic relay
pathways.
6. Which endocrine gland releases hormones that help regulate metabolism?
A. Pineal gland only
B. Thyroid gland
C. Lacrimal gland
D. Sebaceous gland
Correct Answer: B
Rationale: The thyroid secretes hormones that influence metabolic rate, growth, and energy use.
7. What is the main function of the myelin sheath?
A. Store visual memories
B. Create cerebrospinal fluid
C. Increase the speed and efficiency of neural impulse transmission
D. Break down neurotransmitters in the synapse
Correct Answer: C
Rationale: Myelin insulates axons and allows faster saltatory conduction between nodes of Ranvier.
8. Which sensory process converts physical energy into neural signals?
A. Accommodation only
B. Habituation only
C. Projection
D. Transduction
Correct Answer: D
Rationale: Transduction changes environmental energy such as light or sound waves into neural impulses.
9. Which eye structure changes shape to focus light on the retina?
A. Lens
B. Iris only
C. Optic disc
D. Foveal blood vessel
Correct Answer: A
Rationale: The lens adjusts curvature during accommodation to focus near or far objects on the retina.
10. Which retinal receptor is most useful for color vision and sharp detail in bright light?
A. Rod
B. Cone
C. Bipolar glial cell
D. Auditory hair cell
Correct Answer: B
Rationale: Cones support color vision and high acuity, especially in the fovea under bright conditions.
