Monocular rivalry is a phenomenon of human visual perception that occurs when two different images are optically superimposed. During prolonged viewing, one image becomes clearer than the other for a few moments, then the other image becomes clearer than the first for a few moments. These alternations in clarity continue at random for as long as one looks. Occasionally one image will become exclusively visible and the other image invisible.
In the demonstration, one image is a green grating and the other is a red grating. During prolonged inspection, the viewer can see the green grating as clearer than the red grating for a few moments, then the reverse. Occasionally the green grating will be all that is visible and occasionally the red grating will be all that is visible. Occasionally, at transitions, one will briefly see irregular composites of the two gratings (such as the red and green gratings superimposed but with one or two bars of the green grating invisible).

Famous quotes containing the word rivalry:
“It seems to me that we have to draw the line in sibling rivalry whenever rivalry goes out of bounds into destructive behavior of a physical or verbal kind. The principle needs to be this: Whatever the reasons for your feelings you will have to find civilized solutions.”
—Selma H. Fraiberg (20th century)
