psychological Flashcards
perception
when the brain uses sensory stimuli to make sense of the world
influence of schemas
past experiences influence current perception
top down processing
perceptions start with general and move toward specific
selective attention
focusing conscious awareness on a stimulus to the exclusion of others
cocktail phenomenon
ability to attend to only one voice among many blocking out the others
inattentional blindness
failure to see visible objects when our attention is directed toward stimulus
change blindness
failure to notice something is different
figure ground
perceiving an object as distinct from its surroundings
proximity
we group nearby figures together
similarity
we group things together that are similar
continuity
tend to continue shapes beyond their ending points
connectedness
if two objects are touching we perceive them as a single unit
common fate
tend to group together that share a common motion or destincation
closure
our brains fill in gaps to create a whole complete object
retinal disparity
eyes see two different angles of same object
brain tunes those angles into one
convergence
as an object gets closer the muscles in your eyes come together
relative size
closer appears larger
farther appears smaller
interposition
closer is blocking
distant is being blocked
relative clarity
closer appears Clearer
distant appears blurry
texture gradient
closer shows more detail
distant shows less detail
relative height
closer is lower in visual field
distant is higher in visual field
linear perspective
closer lines diverge
farther lines converge
motion parallax
closer object appears faster
stroboscopic movement
series of still pictures moving frantically
phi phenomenon
lights flashing in a series/sequence (loading)
auto kinetic effect
stationary small point of light in an otherwise dark or featureless environment seems to move
shape constancy
shape remains same even if angle changes
size constancy
object size remains even if distance changes
