Perception of radial distance as a function of magnification and truncation of depicted spatial layout

Abstract

A 2×2 factorial design requiring judgments of interobject distance was utilized which separated the effects of magnification per se from the concomitant truncation of the visual field normally effected by optically produced magnification. Only the main effect of magnification was significant, and this was much less than the decreases optically specified by the decreased perspective and texture gradients. © 1983 Psychonomic Society, Inc.
