This paper reports the results of a study to determine if “noisy” visual patterns containing binocular disparity cues could be recognized more accurately than similar patterns with no disparity cues. To obtain a quantitative measure of this visual task three-dimensional patterns were employed based on the metric figures technique developed by Fills and his colleagues. The test results indicated, as expected, that the ability to recognize visual patterns in noise degraded as the noise level was increased. However, discrimination ability measured with figures containing binocular disparity cues degraded at a significantly lower rate (p < .01) than with figures without disparity cues.
