Four-Month-Old Infants' Sensitivity to Binocular and Kinetic Information for Three-Dimensional-Object Shape.
Peer reviewed Peer reviewed
Yonas, 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)

Auditory-Visual Perception of Changing Distance by Human Infants.
Peer reviewed Peer reviewed
Walker-Andrews, Arlene S.; Lennon, Elizabeth M. – Child Development, 1985
Examines, in two experiments, 5-month-old infants' sensitivity to auditory-visual specification of distance and direction of movement. One experiment presented two films with soundtracks in either a match or mismatch condition; the second showed the two films side-by-side with a single soundtrack appropriate to one. Infants demonstrated visual…

The Effect of Intrauterine PCB Exposure on Visual Recognition Memory.
Peer reviewed Peer reviewed
Jacobson, Sandra W.; And Others – Child Development, 1985
Measures of prenatal exposure in 123 infants to polychlorinated biphenyls (PCBs), cord serum PCB level, and maternal report of contaminated fish consumption predicted less preference for a novel stimulus on Fagan's test of visual recognition memory (VRM) at 7 months. Preference for novelty decreased in a dose-dependent fashion and postnatal…

The Development of Infant Sensitivity to Biomechanical Motions.
Peer reviewed Peer reviewed
Bertenthal, Bennett I.; And Others – Child Development, 1985
Examines, in three experiments, infant sensitivity at 20, 30, and 36 weeks of age to 3-dimensional structure of a human form specified through biomechanical motions. Findings are interpreted as suggesting that infants, by 36 weeks of age, are extracting fundamental properties necessary for interpreting a point-light display as a person. (Author/BE)
