【正文】 閾限):the weakest amount of a stimulus required to produce a sensation.Difference threshold(差別感覺閾限):the minimum amount of difference a person can detect between two stimuli.Fovea(中央凹):area consisting of a small depression in the retina containing cones and where vision is most acute.舉例說明什么是差別感覺閾限、絕對(duì)感覺閾限。絕對(duì)感覺閾限就是指剛剛能夠引起感覺的最小刺激強(qiáng)度。The trichromatic theory(三原色理論) The trichromatic theory hypothesizes that we have three kinds of are differentially sensitive to three wavelengths of light:750nanometers, 500nanometers and first wavelength,750nanometers,induces the sensation we call second,500nanometers induces the sensation we call green,And 400 nanometers induces the sensation we call violet. 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(gè)指標(biāo)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。 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(xué)習(xí)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， 雙眼線索：Binocular parallar 雙眼視察眼睛的調(diào)節(jié)2， Physiologyical cues 生理線索 adjustment 調(diào)節(jié) convergence 輻合 The monocular vision(單眼線索):linear perspective線條透視interposition對(duì)象的重迭（遮擋）Light and Shadow明亮和陰影（明暗）texture gradient紋理梯度(結(jié)構(gòu)級(jí)差)motion parallax運(yùn)動(dòng)視差Chapter 5 Memory memory(記憶):the storage and retrieval of what has been learned or experienced.3， Implicit memory(內(nèi)隱記憶):r
