Document Summary

Lecture 18 color perception (cont) & motion perception. Primary visual cortex (v1), opponent color cells are arranged into blobs : same response properties as color cells in the retina. Motion perception has strong survival value: predators and prey animals oth need to sense motion, even animals w/ rudimentary color and form perception abilities have good motion perception systems. Motion perception occurs in the brain: can perceive motion even when nothing in the world is physically moving. Can directly influence our motion percepts through our actions. Six categories of motion: autokinetic motion (real, image motion (real, self motion (real, induced motion (illusory, motion aftereffects (illusory, apparent motion (illusory) Autokinetic motion (real: if you look at point light source in dark room, it appears to jiggle, used as projective test by clinical psych. Clients asked to report words written by this moving light: motion percept is an artifact of eye mov"t, corollary discharge theory (cdt)
