Peer reviewedGordon, F. Robert; Yonas, Albert – Journal of Experimental Child Psychology, 1976
In order to study infants' sensitivity to binocular information for depth, 11 infants, 20 to 26 weeks of age, were presented with real and stereoscopically projected virtual objects at three distances, and the infants' reaching behavior was videotaped. (Author/SB)

Peer reviewedYonas, Albert; And Others – Child Development, 1987
A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

Peer reviewedYonas, Albert; Hagen, Margaret – Journal of Experimental Child Psychology, 1973
Results of this study suggest that 3-year-olds have a good deal of sensitivity to static depth information. (Authors)
