Abstract

Momentary presentation of point targets seen in diplopia were made to six observers using a method of constant stimuli. Fifty presentations were given in a random order at each of 20 levels of binocular disparity from 10° crossed disparity to 10° uncrossed disparity. Thirty-four correct responses out of 50 stimulus presentations constitute the 1% significance level beyond which guessing may be ruled out. Almost all observers were able to respond considerably better than this at disparities up to about 7°, while one highly trained observer showed 90% correct responses or better up to 10° disparity. The average observer was never able to make correct responses to all presentations at any disparity used, and stimuli presented with uncrossed disparity were localized correctly more often than those with crossed disparity.
