Analysis of Errors in Color Agnosia: A Single-case Study. Woodward, T. S, Dixon, M. J, Mullen, K. T, Christensen, K. M, & Bub, D. N
abstract   bibtex   
The performance of an adult with color agnosia (JT) was investigated. Although perceptual color tests clearly demonstrated no difficulty in color discrimination, multidimensional scaling analysis (MDS) revealed that naming errors were constrained to confusions of adjacent points in the three-dimensional visual semantic color space. This pattern of confusions replicated across other tasks drawing on knowledge of color concepts. The findings are interpreted as a partial disruption in mapping perceptual representations of color to prototype nodes in visual semantic color space. We propose that this methodology, already proven useful for investigation of category-specific visual object agnosia, will allow more detailed cross-case comparisons of color recognition disorders.
