the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect.
an organized whole. Psychologists who follow this view emphasize our tendency to integrate pieces of information into meaningful wholes.
the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground).
the ability to see objects in three dimensions although the images that strike the retina are two dimensional; allows us to judge distance.
depth cues, such as retinal disparity and convergence, that depend on the use of two eyes.
a binocular cue for perceiving depth: By comparing images from the two eyeballs, the brain computes distance-the greater the disparity (difference) between the two images, the closer the object.
a binocular cue for perceiving depth; the extent to which the eyes converge inward when looking at an object. The greater the inward strain, the closer the object.
depth cues, such as interposition and linear perspective,available to either eye alone.
an illusion of movement created when two or more adjacent lights blink on and off in quick succession.
perceiving objects as unchanging (having consistent lightness, color, shape and size) even as illumination and retinal images change.
in vision, the ability to adjust to an artificially displaced or even inverted visual field.
