A previous study has reported that sensitivity to luminance modulation on multiple targets decreases when they are perceived as a single object with apparent motion. To investigate the effect of apparent motion on color perception,, we measured color discrimination sensitivity on apparent motion stimuli with color modulation. The stimuli were circles that were sequentially presented on a circular trajectory counterclockwise. The SOA (Stimulus Onset Asynchrony) could control the strength of apparent motion perception. The colors of the stimuli were modulated between two colors during presentation. The observer was instructed to discriminate these two colors. In the results, the color discrimination thresholds at the SOA where apparent motion perception was the strongest were higher than those at other SOAs. One possible explanation of this phenomenon is that color information on multiple targets perceived as a single object is integrated along their perceptual motion trajectory. |
