Document Summary
Represents ability to see objects in three dimensions, although the images that strike the retina are two dimensional. Is present, at least in part, at birth in humans and other animals. Depth cue, such as interposition or linear perspective, available to either eye alone. By comparing images from the two eyes, the brain calculates distance. Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object. Objects are perceived as unchanging (having consistent color, brightness, shape, and size) even as illumination and retinal images change (ex. same color square (blue) near different lights) Perception of form of familiar objects as constant even when retinas receive changing images. Perception of objects as having constant size even when distance from them varies. We know the shape stays constant even if our perspective of it changes (ex. door opening) Ability to adjust to an artificially displaced or even inverted visual field.
