Binocular Rivalry
When two different images are shown, one to each eye, we don't always see a mix of the two. In cases when the images differ in atleast one attribute we may see only one image at a time and this alternates between the two images. (eg: Horizontal and vertical gratings differ in the direction of grating. When horizontal grating is shown to say right eye and vertical grating to left eye we see only...
متن کاملBinocular rivalry
What is binocular rivalry? In humans and animals with forward facing eyes, the two eyes provide views of the world that are only subtly different from one another. In each eye, the lens focuses light into a two-dimensional image on the retina. In normal vision, the disparity between the retinal images provides a stereoscopic cue to the third spatial dimension, depth. But when the eyes are prese...
متن کاملControlling binocular rivalry
Binocular rivalry is the alternating perception that occurs when the two eyes are presented with incompatible stimuli. We have developed a new method for controlling binocular rivalry and measuring its progress. One eye views a static grating while the fellow eye views a grating that smoothly and cyclically varies between two orientations, one the same as the static grating and the other orthog...
متن کاملBinocular rivalry for beginners
Binocular rivalry is a remarkable phenomenon of vision—two dissimilar images are presented simultaneously to each eye, and perception alternates between them. For example, if the left eye views horizontal lines and the right eye views vertical lines, an observer will report seeing one of the images for a few seconds, then the other, then the first again, and so on for as long as he or she cares...
متن کاملStereopsis and binocular rivalry.
Stereopsis and binocular rivalry appear to be incompatible. Rivalry involves suppression of input from one eye at each location in space and time, whereas Stereopsis requires the combination of information from both eyes to yield a sensation of depth. This article presents a theory of the relationship of these phenomena. Evidence from previous work and from experiments reported here shows that ...
