Perception
Process of assembling sensations into
usable mental representations of the
world.
Perception develops over time and
experience.
Past learning helps to create order out of
infinite stimuli we experience every day.
How do we tame the
unruly world?
Size constancy-both those that are inborn
and those we learn from experience
Shape constancy- though your eyes “see”
the differences, your brain’s image remains
the same.
Brightness constancy-color/brightness
remain the same in changing light
conditions.
Space constancy- self motion versus object
motion
Perceptive Organizerscreating meaningful patterns
Figure-ground
nearness/proximity
similarity
continuation
symmetry
closure
Absolute Threshold
Smallest amount of stimuli our
senses can detect 50% of the time.
Measured in limins
Subliminal means below the
threshold.
Congress has outlawed the use of
subliminal messages even though
they have been proven NOT to work.
Perceptual set
We see what we expect to see!!!!
Can influence eye witness
accounts of crimes.
Binocular vision
Depth perception
Closure- covers the blind spot
from the opposite eye
Visual Cliff experiment- proves
that depth perception is learned
Other clues to depth perception
Perceptual constancy
Brightness
Size
Shape
Motion
Schemas
Frameworks that organize
information into meaningful
patterns
Most common– Face Schemas
Perceptual Context
Using the situation or
environment to interpret
sensory information
Optical Illusions
Misperception of sensory
stimuli
ESP-Extra Sensory Perception
Claim that perception can occur away
from the 5 avenues of sensory input
