Stereopsis in monkeys using random dot stereograms: The effect of viewing duration

Abstract The effect of viewing duration on the stereopsis of rhesus monkeys has been investigated by a behavioral method which is based on a two-alternative, forced-choice form discrimination task. The discriminative stimuli were produced in static random dot stereograms so that reliable discrimination could occur only if the disparity creating the form was above the subject's stereothreshold. 2 subjects showed similar form discrimination performance for both crossed and uncrossed disparities, but another four subjects showed higher discrimination performance for crossed than uncrossed disparities for brief viewing durations. A linear, inverse relationship between stereothreshold and viewing duration was found when both values were plotted on logarithmic coordinates. The implications of these results for neural stereodetector pools are discussed.
