Two visual fields of differing brightness presented separately to the two eyes were superimposed. Where perceptual dominance of the brighter or darker field, in a retinal rivalry situation, was manipulated by the imposition of superimposed patterning, no changes were found in pupillary base‐lines. This not entirely unexpected finding is discussed in connexion with other reports that during rivalry there is suppression of a flash‐evoked pupillary reflex elicited from within the non‐dominant field. The interactions of other suppressive and reflex phenomena occurring during vision are considered within this context.
