title: When your brain decides what you see: grouping across monocular, binocular, and stimulus rivalry.
abstract: Research suggests that the neural concomitants of visual rivalry are contingent on the stimulus parameters, implying the existence of three different types of rivalry. Binocular rivalry (dissimilar patterns are presented, one to each eye) is seemingly mediated by interactions between pools of monocular neurons. Monocular rivalry (superimposed patterns are presented to one or both eyes) is presumably the result of competition between neural representations of the patterns. Stimulus rivalry (dissimilar patterns are swapped rapidly between the two eyes) is independent of eye of origin. In the experiment reported here, we integrated these three different types of rivalry into one stimulus. We found that perceptual alternations span the three types of rivalry, demonstrating that the brain can produce a coherent percept sourced from three different types of visual conflict. This result is in agreement with recent work suggesting that the resolution of competitive visual stimuli is mediated by a general mechanism spanning different levels of the visual-processing hierarchy.
