| Abstract(in English) | In metacontrast masking, the visibility of a brief flash of the target is reduced when it is followed by a flash of the mask which is presented in adjacent region. In this study, we investigated the effect of color on metacontrast masking using isoluminant chromatic stimuli. The masking effect was quantified for various color combinations of the target and mask by the paired comparison method. We found that the masking effect was strongest when the two stimuli had the same color. This color selectivity was not consistent with a model of sensitivity change of simple cardinal mechanisms. This indicates chromatic metacontrast masking occurs in higher order color mechanisms as well as opponent mechanisms. |
