retinal rivalry
When the two eyes are simultaneously or successively stimulated on corresponding retinal areas by dissimilar images (e.g. a green source to one eye and a red to the other, or lines orientated in one direction to one eye and in the other direction to the other), there results either an alternation of perception (complete or partial) or even a constant dominance of one eye. (Fig. R11) Syn. binocular rivalry. See Cheshire cat effect; suppression.
