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 sense
receptors and works up to the brain's integration of sensory
information.
● Top-Down Processing. Answer: Information processing guided by
higher-level mental processes, as when we construct perceptions
drawing on our experience and expectations.
● Selective Attention. Answer: The focusing of conscious awareness on
a particular stimulus.
● Inattentional Blindness. Answer: Failing to see visible objects when
our attention is directed elsewhere.
● Change Blindness. Answer: Failing to notice changes in the
environment.
● Psychophysics. Answer: The study of relationships between the
physical characteristics of stimuli, such as their intensity, and our
psychological experience of them.
, ● Absolute Threshold. Answer: The minimum stimulation needed to
detect a particular stimulus 50 percent of the time.
● Subliminal. Answer: Below one's absolute threshold for conscious
awareness.
● Priming. Answer: The activation, often unconsciously, of certain
associations, thus predisposing one's perception, memory, or response.
● Difference Threshold (JND). Answer: Is the minimum noticeable
difference that is needed to detect a difference between 2 stimuli
Also know as Just Noticeable Difference (JND)
● Weber's Law. Answer: The theory stating that the size of a just
noticeable difference is a constant proportion of the size of the initial
stimulus.
● Sensory Adaptation. Answer: Diminished sensitivity as a consequence
of constant stimulation.
● Transduction. Answer: Conversion of one form of energy into another.
In sensation, the transforming of stimulus energies into neural impulses.
● Wavelength. Answer: The distance from the peak of one light or sound
wave to the peak of the next
