1. Which process refers to the conversion of physical stimuli into neural signals?
A. Perception
B. Transduction
C. Adaptation
D. Sensory coding
Correct answer: B
Rationale: Transduction is the process by which sensory receptors convert physical
energy (light, sound, pressure) into neural impulses.
2. Which theory explains how we detect faint signals amid background noise?
A. Opponent-process theory
B. Signal detection theory
C. Gestalt theory
D. Place theory
Correct answer: B
Rationale: Signal detection theory explains decision-making under uncertainty and
accounts for both stimulus intensity and psychological factors.
3. Rod cells are primarily responsible for:
A. Color vision in bright light
B. Peripheral and low-light vision
C. Depth perception
D. Hearing sensitivity
,Correct answer: B
Rationale: Rods are highly sensitive to light and function best in dim conditions,
but they do not detect color.
4. Which structure focuses light onto the retina?
A. Cornea
B. Iris
C. Lens
D. Retina
Correct answer: C
Rationale: The lens changes shape to focus incoming light precisely onto the
retina.
5. The trichromatic theory of color vision proposes:
A. Three types of cones detect red, green, and blue
B. Opposing color pairs process vision
C. Color is processed in the amygdala
D. Rods detect all color wavelengths
Correct answer: A
Rationale: The trichromatic theory states that three cone types respond to short,
medium, and long wavelengths.
6. Gestalt psychology emphasizes that perception is:
A. Random and subjective
B. Based on learned associations only
C. Greater than the sum of its parts
D. Dependent only on sensory receptors
, Correct answer: C
Rationale: Gestalt principles state that the brain organizes sensory input into
meaningful wholes.
7. The absolute threshold is:
A. The maximum stimulus intensity detected
B. The smallest detectable stimulus level
C. The difference between two stimuli
D. A measure of adaptation speed
Correct answer: B
Rationale: Absolute threshold is the minimum intensity needed to detect a
stimulus 50% of the time.
8. The cochlea is involved in:
A. Vision processing
B. Balance regulation
C. Sound wave transduction
D. Olfactory detection
Correct answer: C
Rationale: The cochlea converts sound vibrations into neural signals.
9. Frequency theory explains pitch perception by:
A. Location of vibration along the basilar membrane
B. Rate of neural firing matching sound frequency
C. Color coding of sound waves
D. Random neural activation
Correct answer: B
Rationale: Frequency theory states that neural firing rate matches sound wave
frequency.
