Abstract
Increment thresholds for detecting one brief light (the “probe”) upon another (the “flash”) show extremely steep slopes. This phenomenon, known as cone saturation, is sometimes attributed to sensitivity loss within independently responding classes of cones. To test the validity of this assumption. detection data were obtained using a 640 nm probe and a range of monochromatic flashes as well as a combined 633/541 nm flash. The results, interpreted within the framework of Stiles' displacement laws, refute the simple receptor hypothesis. When monochromatic flashes are used. there is clear involvement of a red green opponent mechanism.
