12 Jul Infants, Even Newborns, Prefer To Look At Attractive Faces Compared To Less Attractive Faces
Infants, even newborns, prefer to look at attractive faces compared to less attractive faces (Slater, et al.,1998). In the study, infants from 1 to 6 days old were shown to photographs of women’s faces. Previously a group of adults had rated one of the faces as significantly more attractive than the other. The babies were positioned in front of a screen on which the photographs were presented. The pair of faces remained on the screen until the baby accumulated a total of 20 seconds of looking at one or the other. The number of seconds looking at the attractive face was recorded for each infant.
