Abstract
Twenty-four male and 24 female subjects were exposed to two dynamic trapezoid illusions under conditions of binocular and monocular regard. Distance and cues to perspective were also varied and the results on these two parameters were consistent with past research. In general, monocular regard resulted in significantly more illusory experiences than binocular regard. Binocular regard was not universally facilitating to veridical perception and, in fact, was detrimental for one-third of the subjects. There was strong evidence, moreover, that the effect of binocular cues was dependent on the particular illusion involved.
