List and explain two binocular cues for depth perception and two monocular cues. Why do we have two different types of cues for depth?
What will be an ideal response?
* Binocular: (1) adjustments of the eye muscles involve movements of the eye muscles as objects get closer and farther to provide the best possible view; and (2) binocular disparity is the disparity in the visual images that each eye sees.
* Monocular: (1) superposition is the property that closer objects partially obscure farther objects; (2) texture gradient is the property that the texture of a surface becomes smoother with distance; (3) linear perspective is the property that parallel lines appear to converge as they recede into the distance; and (4) relative brightness is the property that brighter objects appear closer, and different types of cues allow us to function in a two- and three-dimensional world.
