Abstract

MIRANDA, SIM6N B., and FANTZ, ROBERT L. Visual Preferences of Down's Syndrome and Normal Infants. CHILD DEVELOPMENT, 1973, 44, 555-561. The differential visual responses of 20 DowN's syndrome (DS) and 20 normal infants (CA 8 months) to 13 pairs of visual targets were compared. Although DS Ss overall looked longer at the stimuli than normal Ss, they showed a response differential in only 3 stimulus pairs compared with 11 for the normals. 6 of the stimulus pairs elicited significant DS-normal differences--differences related to type of stimulus variation. Form of contour, the variation least attributable to inferior vision in DS infants, elicited the most marked group difference. The results suggest the value of this approach for studying early perceptual-cognitive development in defective infants and point to an early relationship between visual-attentional responses and intellectual potential.
