| 概要 |
This paper reviews the theoretical and empirical studies on Emmert' s law describing relationships between sizes and distances of an afterimage. The paper is divided into six main parts. The first par...t introduces the origin of the problem of Emmert's law. The second part describes three interpretations of Emmert's law discussed previously: (1)the law as geometrical optics, (2)the law stating relationships of perceived size and physical distance, and (3) the law stating relationships of perceived size and perceived distance. The present paper adopts the third interpretation. The third part describes that Emmert's law is equivalent to the size-distance invariance hypothesis when the third interpretation is valid. The forth part reviews various empirical studies of Emmert's law. The fifth part describes experiments to estimate the perceived distance by using Emmert's law. Finally, the sixth part reviews the results of studies examining the range of viewing distance to which Emmert's law can be applied.続きを見る
