| retinal disparity, convergence, accommodation | three ocular cues in perception-depth/distance |
| binocular | both eyes viewing simultaneously |
| monocular | accommodation as an ocular cue |
| interposition | cue-objects father obscured by objects nearer |
| linear perspective | parallel lines appear to converge as approach horizen |
| paterns of shading | makes possible to see objects distinct from backgrounds |
| motion parallax | moving - objects passing move rapid/ near horizon slow |
| phi phenomenon | visual illusion light traveling between 2 stationary bulbs |
| autokinetic effect | illusion led to changing plane lightes from steady to flashing |
| constancy | allows us to reconginze familar objects |
