title: 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.
