2-B-20 2種の運動刺激間における知覚的ずれ(2002年度 日本基礎心理学会第21回大会優秀発表賞)

抄録

Motion- and luminance-defined motion (MDM and LDM) were perceived to be misaligned when they were presented physically with the same speed and in phase (perceptual offset). Motion-defined motion is the motion of patterns defined by the direction of the local motion. In this study we examined the effects of the global motion speed (physical and perceptual) of MDM and LDM on the amount of the perceptual offset in order to explore the origin of this phenomenon. The null point for the apparent offset was calculated by using a probit analysis. The calculated offset increased as the physical global motion speed increased. The offset phenomenon reported here can be interpreted as a spatio-temporal conversion of differences in processing time for LDM and MDM.
