A reevaluation of angle-contingent color aftereffects.

Abstract

It has been argued that adaptation to a series of angles with vertices pointing up and illuminated in one color, and to angles with vertices pointing down and illuminated in the opponent color, results in color aftereffects that are contingent on angle direction. In the present paper, using a number of test figures, we demonstrate that adaptation to these ascending/descending angles results in color aftereffects that can be accounted for in terms of spatially localized, orientation-color pairings. In the light of our results, we suggest that previous inferences concerning angle-contingent color aftereffects should be reconsidered.
