Abstract

With random letter stereograms as stimuli, three groups of Ss made judgments of relative size and relative distance of paired stereo images varying in size but not in distance, as indexed by amount of retinal disparity. Ss in Group D were instructed that members of the stereo pairs differed in size and distance; Ss in Group S were told that there were distance differences but not size differences; Ss in Group N were told nothing about either relative sizes or relative distances. Differences in instructions regarding relative size did not affect relative size judgments: Ss typically reported the objectively larger image as being larger. Ss in all three groups reliably reported the objectively smaller image as being the more distant image.
