Document Summary

Retinal disparity = objects project images to slightly different locations on right/left retinas so left/right eyes se differently = principle binocular cue (closer an object gets = greater disparity) Convergence sensing the eyes converging towards each other as they focus on closer objects. Monocular depth cues = clues about distance based on the image in either eye alone. A) motion parallax = result of active use of eye in viewing world near objects appear to move more rapidly (move across retina at different rate) Perceptual constancy = tendency to experience a stable perception in the face of continually changing sensory input (view object as having stable size/shape) Optical illusion = an apparently inexplicable discrepancy between the appearance of a visual stimulus and its physical reality. Impossible figures = objects that can be represented in 2d pictures but cant exist in 3d space. Sound waves = vibrations of molecules travelling through a physical medium (e. g. air)
