Color categories only affect post-perceptual processes when same- and different-category colors are equally discriminable

posted on 2023-06-08, 17:36 authored by Xun He, Christoph Witzel, Lewis Forder, Alexandra Clifford, Anna FranklinAnna FranklinPrior claims that color categories affect color perception are confounded by inequalities in the color space used to equate same- and different-category colors. Here, we equate same- and different-category colors in the number of just-noticeable differences, and measure event-related potentials (ERPs) to these colors on a visual oddball task to establish if color categories affect perceptual or post-perceptual stages of processing. Category effects were found from 200 ms after color presentation, only in ERP components that reflect post-perceptual processes (e.g., N2, P3). The findings suggest that color categories affect post-perceptual processing, but do not affect the perceptual representation of color.
