Document Summary
Psychology 1xx3 notes depth, distance and motion mar 7th, 2010. We can make depth/distance decisions because we can create a mental image of a three-dimensional world, based on a combination of tap- down and bottom-up processing. Remarkably, new visual input from a 2-dimensional retinal surface is processed along with our existing knowledge of the environments objects and surfaces to create this 3-d world. This essential skill is aided by the many cues that have been incorporated into evolution of depth perception. Def"n of convergence: a cue to depth resulting from the way our eyes turn inwards to fixate on a specific point. There are two types of binocular cues to depth perception.

You can feel this yourself if you look at your finger at arm"s length and then slowly bring it towards you while still focusing on your finger.
