Research Article Color-Binding Errors During Rivalrous Suppression of Form

ABSTRACT—How does a physical stimulus determine a con-scious percept? Binocular rivalry provides useful insights into this question because constant physical stimulation during rivalry causes different visual experiences. For example, presentation of vertical stripes to one eye and horizontal stripes to the other eye results in a percept that alternates between horizontal and vertical stripes. Presen-tation of adifferent color to each eye (color rivalry) produces alternating percepts of the two colors or, in some cases, a color mixture. The experiments reported here reveal a novel and instructive resolution of rivalry for stimuli that differ in both form and color: perceptual alternation between the rivalrous forms (e.g., horizontal or vertical stripes), with both eyes ’ colors seen simultaneously in separate parts of the currently perceived form. Thus, the colors presented to th
