Monocular-contingent and binocular-contingent aftereffects

Psychophysics of binocular vision.

“…The assumption is that the vertical and horizontal adapting gratings with their specific colored grounds stimulate different orientation-color-contingent cell populations, so that in the test phase, the opponent cell populations are more active in triggering neural responses. McCollough's original discovery had led to a number of studies, such as the motion-contingent color aftereffect and its reverse, the color-contingent motion aftereffect, both of which provided evidence for specific channels in the human visual system* To show that each eye involved in binocular vision is different from the same eye used for monocular vision, and that there are unique binocular detectors existing independently of monocular detectors, Jiao et al (1983) replicated an experiment on the McCollough effect reported by T.R. Vidyasager (1976).…”

“…Could the specific monocular and binocular aftereffects be produced on the spiral aftereffect? In our laboratory Jiao et al (1983) adapted the observer's left eye to a contracting spiral, the right eye also to a contracting spiral, but both eyes binocularly to an expanding spiral. The result was what we expected: the monocular and binocular aftereffects did not cancel each other, but appeared to expand and contract in opposite directions with monocular and binocular observation respectively.…”
