1. What is the main purpose of sensory systems?
A. To store memories
B. To convert energy into neural signals
C. To generate emotions
D. To control motor behavior
Answer: B
Rationale: Sensory systems transduce physical energy (light, sound, etc.) into
neural signals.
2. Perception refers to:
A. Detecting energy only
B. Neural firing only
C. Interpretation of sensory input
D. Reflex actions
Answer: C
Rationale: Perception involves organizing and interpreting sensory information.
3. Psychophysics studies:

B. Relationship between stimuli and perception
C. Eye structure
,D. Hormone function
Answer: B
Rationale: Psychophysics links physical stimulus properties to perception.
4. Absolute threshold is:
