Three lights in various orientations were presented to two trained Ss. The Ss adjusted the three lights until they appeared equidistant. The results supported earlier work of a similar nature, in that the higher light was perceived as closer and horizontal separation between lights produced no significant differences in depth settings. The phenomenon was shown to occur with monocular vision, fixated vision, large angular separation of the stimuli, and with different directions of regard with respect to the fixation point. The relationship to other research is discussed.
