depth perception: The ability to view the world in threedimensions and to perceive distance

binocular disparity: The difference between the images that reach the retina of each eye; this

disparity allows the brain to estimate distance

monocular cues: Signals that allow us to perceive distance and depth with just one eye

motion parallax: The change in position of the image of an object on the retina as the head moves

from side to side, providing a monocular cue to distance

relative size: The phenomenon by which, if two objects are the same size, the one that makes a

smaller image on the retina is perceived to be farther away; a monocular cue

linear perspective: The phenomenon by which distant objects appear to be closer together than

nearer objects; a monocular cue
