THE A+ ADVANTAGE: ACE 2026/2027 NEU 325 SENSATION
AND PERCEPTION CERTIFICATION EXAMINATION|
COMPREHENSIVE Q&A
● Bottom-Up Processing. Answer: Analysis that begins with the sensory
receptors and works up to the brain's integration of sensory
information.
Externally Driven.
● Perception. Answer: Selecting, organizing, and interpreting what
comes in your window as meaningful objects and events.
● Top-Down Processing. Answer: Guided by higher level mental
processes, such as experience, motivation, and expectations
● Perceptual Adaptation. Answer: Ability to adjust to an artificially
displaced field
● Psychophysics. Answer: The study of how physical energy relates to
our psychological experience
● Transduction. Answer: Conversion of one form of energy into another
● Absolute Threshold. Answer: The minimum stimulation needed to
detect a particular stimulus 50% of the time
, ● Difference Threshold
(JND). Answer: The minimum difference a person can detect between
any 2 stimuli 50% of the time
● Weber's Law. Answer: Difference thresholds differ by a constant
percentage rather than a constant amount.
● Signal Detection Theory. Answer: Predicts when we will detect weak
stimuli amid background noise
Depends on experience, expectations, motivation, and fatigue level
● Subliminal Messages. Answer: Stimuli below one's absolute threshold
Unconsciously sensed
Works to an extent
● Sensory Adaptation. Answer: Diminished sensitivity as a consequence
of constant stimulation
● Wavelength. Answer: Determines Hue
● Amplitude. Answer: Determines Brightness
