Abstract	A looming paradigm was used to determine what depth information infants process in addition to that provided by the expansion of a single, closed contour of an object. A total of 18 male and 15 female infants aged 22-48 days watched a film in which the circular elements and inter-element spaces of the projected image alternately expanded and contracted. A display containing 800 black circles elicited significantly more head responses directed away from the screen than displays having either one or three circles of the same size. The differences were only found in the expansion trials. Infants thus processed depth information provided by the expanding spaces between elements or movement of the elements toward the peripheral visual field. The results were in agreement with Gibson's (1966, 1968) description of the adequate stimulus for perceived movement in depth. (Author/BRT)
