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 reviewedSkouteris, H.; And Others – Child Development, 1992
Results of 3 experiments indicated that 12 month olds, but not 8 and 10 month olds, looked longer at objects of a different shape from test objects than at the test objects. Twelve month olds recognized rectilinear, but not curvilinear, forms. They recognized differences in forms for three-dimensional, but not two-dimensional, objects. (BC)

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 reviewedBushnell, Emily W.; Boudreau, J. Paul – Child Development, 1993
Emphasizes the role that motor development may play in determining developmental sequences in other domains, such as haptic or tactile perception and depth perception. Maintains that there is a high degree of fit between the developmental sequence in which certain perceptual sensitivities unfold and the ages at which the corresponding motor…
