Newborn preference for a new face vs. a previously seen communicative or motionless face

Abstract Newborn infants prefer to look at a new face compared to a known face (still-face). This effect does not happen with the mother-face. The newborns could be attracted by the mother-face because, unlike the still-face, it confirms an expectation of communication. Fifty newborns were video-recorded. Sixteen of them were recruited in the final sample: nine were exposed to a communicative face and seven to a still-face. All the 16 newborns were successively exposed to two preference-tasks where a new face was compared with the known face. Only newborns previously exposed to a still-face preferred to look at a new face instead of the known face. The results suggest that the newborns are able to build a dynamic representation of faces.
