ORIENTATION SPECIFIC COLOR ADAPTATION AT A BINOCULAR SITE

Abstract

MCCOLLOUGH1 found that after alternate viewing of vertically oriented red gratings and horizontally oriented blue gratings, achromatic gratings appear tinted blue when oriented vertically and pink when oriented horizontally. This indicates the existence of colour specific edge detectors in the visual system. Further, since interocular transfer of the effect was not possible, McCollough concluded that no binocular cells are involved in this type of adaptation. This view has been supported by many investigators2-5 who used different paradigms. But their failure to illustrate orientation-contingent colour adaptation at a binocular locus may be attributable to the fact that most of their experim..
