NEWBORNS FORM PROTOTYPES IN LESS-THAN 1 MINUTE

Past research demonstrated that newborns looked longer at live faces and two-dimensional still images of the mother than at the faces and images of strangers (Bushnell, Sai, & Mullin, 1989; Field, Cohen, Garcia, & Greenberg, 1985; Walton, Bower, & Bower, 1992). This study examined schema (prototype) theory as a basis for newborn's preference for the mother's face by creating composite (prototype) faces with a pixel averaging technique. Results obtained with a preferential operant-sucking procedure indicated that formation of a representation of faces was rapid. Newborns preferred to look at a composite of presented faces rather than a composite of unseen faces on the first-look presentation of each. The effect faded over the duration of the experiment.
