Document Summary

Grouping of elements (gestalt laws of grouping) Binocular cues (2 eyes) in order to focus. Binocular disparity the difference in image location of an object seen by the left and right eyes, resulting from the eyes" horizontal separation (parallax) Convergence the closer an object, the more inward our eyes need to turn brain. Gives you the right angle you need to see something. Linear perspective parallel lines appear to converge in the distance. Shading less textured when they are far from the viewer. Size constancy (relative size) our perceptions of the size of objects are relatively constant despite the fact that the size of objects on the retina vary greatly with distance. Brightness constancy we perceive objects that we see at night or in poor lighting their retinal images change when we view them from different angles to be the same brightness as they appear during the day. Top-down processing see the whole and ignore the details.
