Document Summary

Theories summary (chapter 3: theories of color vision. There are two theories about how people can see colors: trichromatic theory, opponent- process theory. Proposed three types of cones: red, blue and green cones. The combination of the three cones and the rate at which they fire their message to the brain"s vision center that determines the color that will be seen. Proposed four primary colors: red, green, blue and yellow. The colors are arranged in pairs: red with green and blue with yellow. If one member of a pair gets strongly stimulated, the second member gets inhibited, so it cannot work. For instance, there cannot be reddish-green: theories of hearing. There are three primary theories about how the brain receives information about pitch: place theory. In this theory, the pitch a person depends on where the hair cells that are stimulated are located on the organ of corti: frequency theory.
