Perception of change in surface orientation induced by luminance change -- Effects of presence and luminance of an adjacent surface --

Abstract (in Japanese) (See Japanese page) 
(in English) perceive shapes of objects from shading. In other words, humans perceive spatial change of surface orientation from spatial change of surface luminance. Our previous study reported that temporal change of surface orientation was seen from temporal change of surface luminance. In the present study, we examined the effects of the presence and luminance of an adjacent surface on the perception of change in surface orientation induced by luminance change. The presence of the adjacent surface enhanced the perceived change in orientation of the test surface. In addition, the perceived orientation of the test surface tended to be downward or upward when the luminance of the adjacent surface was higher or lower than the mean luminance of the test surface, respectively. These results suggest that the presence and luminance of an adjacent surface affect the perception of temporal change in surface orientation induced by the temporal change of surface luminance.
