PSYC 230 UIUC EXAM 1 2026 QUESTIONS
WITH VERIFIED ANSWERS GRADED A+
◉ Are there really 5 senses? Answer: No, there are from 7-12
different senses
◉ neural transduction Answer: receptors, transduction and neural
response
◉ Sensation Answer: activation of sensory receptors due to a
stimulus in the environment (physical stimulus---->neural signal)
◉ Phenomenology Answer: internal experience that everyone has of
the external world around them
◉ Aristotle and the Five senses Answer: Aristotle said there were
five senses - smell, sight, touch, taste, and hearing - but science
suggests there are many more than that
◉ Thomas Young Answer: showed that light, like waves, could be
diffracted, color recptors
,◉ Johannes Mueller Answer: doctrine of specific nerve energies
(distinct senses)
◉ Von Helmholtz Answer: perception is constructed from both
senses and cognitive processes, unconscious inference, three basic
color receptors
◉ Hering Answer: colors are perceived through 2 pairs of opposing
colors (four primary colors, not three)
◉ Weber's Law Answer: the just noticeable difference between two
stimuli is based on a proportion of the original stimulus rather than
on a fixed amount of difference
◉ Fechner Answer: father of psychophysics, the study of the relation
between physical stimuli and the perception they elicit
◉ Fechner's Law Answer: sensation is a logarithmic function of
physical intensity
◉ Gestalt Psychology Answer: the whole is greater than the sum of
its parts
, ◉ Law of Proximity (Gestalt) Answer: elements close to one another
tend to be perceived as a unit
◉ Law of Common Fate (Gestalt) Answer: visual elements that move
in the same speed and/or direction are parts of a single stimulus
◉ law of closure (gestalt) Answer: we tend to see complete figures
even when part of the information is missing
◉ Law of Similarity (Gestalt) Answer: objects that are similar tend to
be grouped together
◉ Law of Good Continuation (Gestalt) Answer: elements that appear
to follow the same pathway tend to be grouped together
◉ Gibson and Direct Perception Answer: sensation is perception,
what you see is what you get
◉ Information Processing Approach Answer: a perspective on
understanding cognition that divides thinking into specific steps and
component processes (LIKE A COMPUTER)
