TermDefinition
perception the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
selective attention our tendency to focus on just a particular stimulus among the many that are being received --> pay attention to only a few at a time
cocktail party effect you focused your attention on one particular voice
selective inattention our directed attention is elsewhere, causing us to miss other stimuli
inattentional blindness failing to see visible objects when our attention or focus is directed elsewhere *UNAWARE*
change blindness failing to notice changes in the visual environment *SWITCH*
priming the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response --> *buttering them up*
perceptual set a mental disposition to perceive one thing and not another
figure ground the organization of the visual Field into objects (the figures) that stand out from their surroundings (the ground)
proximity a Gestalt law of grouping --> we group nearby figures together
continuity a Gestalt law of grouping --> we perceive smooth, continuous patterns rather than discontinuous ones
closure a Gestalt law of grouping --> we fill in gaps to create a complete, whole object
visual cliff a model of a cliff with a "drop-off" area that was actually covered by sturdy glass
binocular cues depth cues ghat depend on the use of two eyes
retinal disparity the brain computes distance -- the greater the disparity (difference) between the two images, the closer the object
convergence the inward angle of the eyes focusing on a near object
monocular cues depth cues available to each eye separately
relative height we perceive objects higher in our field of vision as farther away
relative size the one that casts the smaller retinal image is farther away
interposition if one object partially blocks our view of another, we perceive it as closer
relative motion the motion or speed of any object in respect it a particular point
linear perspective parallel lines appear to meet in the distance
light & shadow shading produces a sense of depth
stroboscopic movement our brain perceives a rapid series of slightly varying images as continuous movement *CARTOON EFFECT*
phi phenomenon we perceive two adjacent stationary lights blinking as one single light moving back and forth *LIGHTED SIGNS*
perceptual constancy top-down process that recognizes objects without being deceived by changes in their color, brightness, shape, or size
color constancy perceiving familiar objects as having consistent color
brightness constancy we perceive an object as having a constant brightness
shape constancy we perceive an object as having an unchanging shape
size constancy we perceive an object as having an unchanging size
perceptual adaptation the ability to adjust to changed sensory input
