SENSATION AND PERCEPTION FINAL
PAPER COMPLETE QUESTIONS AND
ACCURATE SOLUTIONS STUDY GUIDE
●● perception
Answer: the psychological process of organizing and interpreting
sensory information.
●● Transduction
Answer: The conversion of sensation signals into a neurological signal
that can be perceptually understood (the bridge between sensation and
perception).
●● bottom-up processing
Answer: analysis that begins with the sensory receptors and works up to
the brain for understanding.
●● top-down processing
Answer: analysis of stimuli that begins with the brain (already have an
idea of what something is supposed to be), which allows our sensory
organs to better detect what we are sensing.
●● inattentional blindness
, Answer: failing to see visible objects when our attention is directed
elsewhere. (Example - Moonwalking Bear)
●● change blindness
Answer: failing to notice changes in the environment. (Example - Person
Swap)
●● absolute threshold
Answer: the minimum stimulation needed to detect a particular stimulus
50 percent of the time.
●● signal detection theory
Answer: a theory that our ability to perceive stimuli depends partly on a
person's experience, expectations, motivation, and alertness.
●● subliminal perception
Answer: the registration of sensory input without conscious awareness
(below our absolute threshold)
●● difference threshold
Answer: the minimum difference between two stimuli required for
detection 50 percent of the time. Also called the just noticeable
difference (jnd).
