Document Summary
Completely separated functionally: specific functions like language occur either in the left or the right hemisphere but not in both. Trichromatic theory: color vision is a result from activity in three different types of cones (each sensitive to different wavelengths) The only cells that are firing are the green and yellow (the opposite of blue and red in the image): colors are psychological products of our visual system. Organization and interpretation of sensory input to create a representation of the world. What are the boundaries of objects (how do we segment the visual world?) Edge detection (where are edges in the world?) Where do boundaries occur?: problem: boundary assignment (which surface does the boundary belong to?) Unit formation (how are different surfaces grouped together into single perceptual units: problem: edge integration and interpolation. Many kinds of edges: brightness, color, texture, motion, depth. Representing different things: lighting, shadow, paint/color, texture/material, boundaries.
