Demonstration that blur affects binocular rivalry with monocular occlusions. A) A stereogram depicting a well-focused textured background monocularly occluded by a blurred textured surface. Cross fuse to see the image in depth. Use the fixation circles to guide fixation. Direct your gaze and attention to the background near the edge of the occluder. Most people experience little rivalry in this case, and can easily read the background text. B) The same stereogram, but with the occluding surface equally focused. Again cross fuse and direct your gaze and attention to the background near the occluder's edge. Most people experience rivalry near the foveas making it somewhat difficult to read the text on the background. C) Text for making cutouts. Cut on the dotted lines to make a background (left) and occluder (right). Hold them such that the occluder is near and on the right partially occluding the background.
