title: Dichoptic completion, rather than binocular rivalry or binocular summation.
abstract: When one monocular image contains a red square partly occluding a green square, and the other monocular image is the same except that the green square is partly occluding the red one, the two images resemble each other's amodal completion. Observers typically perceive two complete squares as if the red and green surfaces are transparent or penetrating each other at their overlapping image location, which never appears yellow. With this example, we introduce dichoptic completion as a perception with the following characteristics. (1) Similar to binocular rivalry, it is evoked by dichoptic stimuli with monocular images so disparate that they cannot arise from physical scenes; however, (2) it occurs when objects inferred from one monocular image are identified with, or do not conflict with, objects inferred from the other; and, consequently, (3) it is a form of perceptual superposition, distinct from the result of binocular summation or rivalry.
