Regan, J. K., & Hansmann-Roth, S.
Witzel, O'Regan and Hansmann-Roth ask whether individual differences in perceiving the dress come from a general perceptual strategy, the way an observer attributes features in a two-dimensional image either to surfaces or to their illumination. They reanalysed data from two earlier experiments on the dress and on colour constancy, and found that colour perception of the dress is strongly related to individual differences in colour constancy. Two online surveys then measured perception of several colour-ambiguous images alongside colour constancy, gloss perception, the subjective grey point, colour naming, and an image with ambiguous shading. The dress result replicated and extended: the differences are due to implicit assumptions about the illumination. The rest did not. Individual differences in the other phenomena were independent of the dress and of each other, which undermines the idea of an overall perceptual strategy and leaves one specific computation in which people genuinely differ.
