This paper describes and tests a new psychological theory of dimensional integrality. Integrality refers to the phenomenon of physically independent dimensions appearing fused into a single perceptual attribute such that the physically separable dimensions are not perceptually separable. The theory proposes that all stimuli are perceived as combinations of perceptually independent dimensions, but that for integral stimulus sets the perceptual dimensions do not correspond to the physically independent dimensions. Integrality is demonstrated psychophysically by interaction in psychological similarity space between physically independent dimensions.
