Binocular rivalry refers to alternations of perception when incompatible images are presented to the two eyes. While the percept is most often of a single monocular image, suggesting monocular spatial integration, perception can also resemble a patchwork of parts of both eyes’ images, suggesting spatial integration at a higher level of processing. Here we investigated the spatial profiles of integration during binocular rivalry to differentiate higher- from lower-level influences on spatial integration during rivalry. Our results suggest that image-based integration, typically referred to as higher-level, is subject to similar spatial constraints as monocular, eye-based integration, suggesting both rely on similarly sized receptive fields and thus levels of processing.
