Trichromatic+Theory

toc = = = Definition: = The theory of color vision suggesting that three types of cones in the retina each make a maximal chemical response to one of three colors- blue, gree, or red. pp. 77 Gen Psych Chapter 3

= Examples: = Research conducted in the 1950s and 1960s by Nobel prize winner George Wald (1964; Wald, Brown, & Smith, 1954) suports the trichromatic theory. Wald discovered that even though all cones have basiclly the same structure, the retina does indeed contain three kinds of cones. Subsequent research demonstrated that each kind of cone is particularly sensitive to one of three colors- red, blue, or green (Roorda & Williams, 1999).
