title: Dichoptic opponent hue cancellations.
abstract: Relative to monoptic opponent hue cancellations, dichoptic cancellations, which were possible over most of the visible spectrum, generally required more blue or less yellow to cancel the opponent yellow or blue response and less green to cancel the opponent red response. Differences between dichoptic and monoptic red-to-cancel-green functions were wavelength dependent. These data were approximately predicted by a model in which monoptic cancellations are based at the receptor level, whereas dichoptic cancellations are based upon cancellations of postreceptor opponent hue responses at a central level in the visual system. The model also makes reasonable predictions of other dichoptic hue-matching data.
