|
attention
|
the process of directing and focusing certain psychological resources, usually by voluntary control, to enhance information processing, performance, and mental experience
|
|
|
binocular disparity
|
a depth cue based on the difference between the two retinal images
|
|
|
bottom-up processing
|
aspects of recognition that depend first on the information about the stimulus that comes up to the brain form sensory receptors
|
|
|
convergence
|
a depth cue involving the rotation of the eyes to project the image an object on each retina.
|
|
|
interposition
|
a depth cue whereby closer objects block one's view of objects farther away.
|
|
|
linear perspective
|
a depth cue whereby the closer together two converging lines are, the greater the perceived distance.
|
|
|
looming
|
a motion cue involiving a rapid expansion in the size of an image so that it fills the available space on the retina.
|
|
|
PDP models
|
an approach to understanding object recognition in which various elements of the object are thought to be simultaneously anazlyzed by a number of widely distribute but connected neural units in the brain.
|
|
|
motion parallax
|
a depth cue whereby a difference in the apparent rate of movement of different objects provides information on the relative distance of those objects
|
|
|
perceptual constancy
|
the perceptin of objects as constant in size, shape, color and other properties despite changes in their retinal image.
|
|
|
relative size
|
a depth cue whereby larger objects are perceived as closer than smaller ones
|
|
|
schemas
|
basic units of knowledge; based on experience of the world
|
|
|
stroboscopic motion
|
an illusin in which lights or images flashed in rapid succession appear to be moving
|
|
|
texture gradient
|
a graduated change in the texture, or grain, of the visual field whereby changes in texture across the retinal image are perceived as chanes in distance; objects with finer less detailed textures are perceived as more distant
|
|
|
top down procesing
|
the aspects of recognition that are guided by higher level cognitive processes and psycholgical factors like expectations
|
