The visual preferences of human infants for faces that varied in their
attractiveness and in their symmetry about the midline were explored.
The aim was to establish whether infants' visual preference for attra
ctive faces may be mediated by the vertical symmetry of the face. Chim
eric faces, made from photographs of attractive and unattractive femal
e faces, were produced by computer graphics. Babies looked longer at n
ormal and at chimeric attractive faces than at normal and at chimeric
unattractive faces. There w were no developmental differences between
the younger and older infants: all preferred to look at the attractive
faces. Infants as young as 4 months showed similarity with adults in
the 'aesthetic perception' of attractiveness and this preference was n
ot based on the vertical symmetry of the face.
