Distributions of response ratios for stimuli with and without remote fields.
(A) Remote fields had same chromaticity as stimuli. Median: 0.88. Black data points with crosses indicate corresponding values for psychophysical data of eight subjects (median: 0.92).
(B) Remote fields and stimulus had opponent chromaticities. Median: 1.02. Note that in only a subset of experiments two remote field colors were used. The different results for the two conditions indicates that the influence of remote fields is color specific.
