Peer reviewedGranrud, Carl E.; And Others – Child Development, 1984
A total of 20 infants either five or seven months of age viewed computer-generated random-lot displays in which accretion and deletion of texture provided the only information for contours. Infants of both age groups showed significant preferences to reach for the apparently nearer regions in the displays. (Author/RH)

Peer reviewedCraton, Lincoln G.; Yonas, Albert – Child Development, 1988
A sample of 44 infants of five months of age showed a significant reaching preference for the apparently nearer region of a computer-generated display. This indicated that the infants were sensitive to boundary flow information for depth at an edge. (RH)

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)
