アーヴィン・ロックの運動知覚論 : 動画によるプレゼンテーションを輻輳させて

抄録

Irvin Rock maintained that the perception is indirect, at least in the sense that some conscious perceptions are caused by other prior conscious perceptions rather than being directly and independently determined by retinal stimulation. The present paper, from his point of view, reviews a variety of motion phenomena which include stereokinetic movement, kinetic-depth effect, apparent motion, appature viewing, Ames' Window, and so on. Using Macromedia Director 8, we prepared a computer-developed motion program of the related phenomena. Through the examination of the Rock's explanation and the program, we identified some kinds of principles such as the preference of rest (apparent quiet), especially the rest of background, and the preference of solution to be moving three-dimensionally. Furthermore, the necessity of comparison among the presentation devices such as a turntable, a film, a video, and a computer are proposed, in order to specify their effects on motion perception.
