Interposition and Size Constancy: A Developmental Study

Abstract

27 children (mean age 6.7 yr.) and 84 adults (mean age 26.3 yr.) were asked to judge the sizes of human figures in photographs. Half the cards contained interpositional depth cues while the other half did not. Both groups of subjects showed better size constancy with interposition present than without it.

The horizon line, linear perspective, interposition, and background brightness as determinants of the magnitude of the pictorial moon illusion

“…Mandes (1985) presented children and adults with images of human figures and asked the participants to judge the size of each figure. Half of the images contained interposition, and half did not.…”

Perception of Sound-Obstructing Surfaces Using Body-Scaled Judgments

“…Early artists 88 GORDON AND ROSENBLUM established that observers are able to detect depth and relative object positions from the interposition of visible surfaces (e.g., Mandes, 1985;Olson, 1975). Research on stationary occlusion (i.e., involving stationary surfaces and observers) has shown that the interposition of surfaces can induce perception of depth and surface separation (Cutting & Vishton, 1995;Mandes, 1985).…”
