Granrud, 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)

Granrud, Carl E.; And Others – Journal of Experimental Child Psychology, 1984
Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)
