Abstract
In a previous investigation individual cues to distance were found to have little effect on size perception. An explanation of these findings was sought by investigating (1) the effect of differences in distance information in the standard and comparison fields (2) testing the effect of relative distance cues on the perception of size. Size judgments of a standard object were made under two comparison field conditions, with only relative distance cues present and with only absolute distance cues present. The results of this experiment were essentially the same as those in the earlier work.
