Document Summary

Bottom-up processing: lower levels of stimulus processing to upward higher centers of the brain involving process and understanding. Accomodation: how much eye muscles have moved to focus. Proprioceptive input: signals from ciliary muscles to the brain. Binocular convergence: how much eyes have rotated in tells us how far or near an object is. Binocular disparity/stereopsis: cue that results because the closer an object is, the more disparity between the two eyes. The brain can estimate how far an object is. Top-down processing: perception based on our knowledge and desire of what should be there. Linear perspective: converging of parallel lines toward a more distance point. Relative size: if two objects are the same size, the one with the smaller visual angle is the one further away. Interposition: describes how nearer objects obscure objects that are further away. Light and shading: how 3d objects cast shadows and reveal reflections, tells us their relative location.
