| Abstract: | The reaching behavior of 12 infants in the presence of solid objects and pictures of objects placed within and beyond possible contact distance was videotaped in 3 sessions at 15, 19, and 24 wks of age. From 15 wks onward the Ss adjusted their reaching behavior to changes in the physical distance of stimuli. However, infants who attempted to manipulate the solid objects tended to reach for pictured objects in the same way. The different amounts of visual attention Ss paid to objects and pictures indicated that they could visually discriminate between the flat and solid stimuli, but it seemed this capacity for depth perception could be obscured by the rather compulsive tendency of young infants to manipulate patterned surfaces situated within reach.
