Outline of Final Research Achievements

We carried out psychophysical experiments of gloss discrimination and visual search, and ERP measurements in order to see whether gold perception was different from other gloss perceptions with different colors. It was obtained in the psychophysical experiments that thresholds for gloss discrimination were not different across four colors, including gold, at any gloss level, and that response times for gold did not show particular difference in detecting a target in a conjunction visual search paradigm. In the ERP measurements, it was shown that ERP responses for gold seemed different from that for glossy red. These results suggest that particular characteristic of gold perception might be caused in a higher level of the visual system.
