The trichromatic theory also accounts for the sensation of colors other than the three primary sensation of orange,for example,takes place because a wavelength of light such as 650 nanometers will cause the simultaneous firing of some neurons that usually fire at 750 nanometers and some that fire at 500nanometers White light is sensed when all of the wavelengths arrive at the retina in a random or scrambled fashion.(了解)顏色的3個指標hue色調(diào)brightness亮度、明度saturation飽和度Chapter 4 Perception perception(知覺):the represesentation of what is perceived。basic ponent in the formation of a 。 Characteristics of Perception(知覺的特性):perception integration整體性figureground perception選擇性perceptual inference理解性learning to perceive學習性perceptual constancy恒常性 知覺整體性的組織化原則:proximity接近性continuity連續(xù)性similarity相似性simplicity簡潔性closure封閉性 The binocular vision of depth perception(深度知覺的雙眼線索)1，
