One surprising finding of infant face perception is that infants will look longer at attractive faces than unattractive ones. unattractive faces than attractive ones. upside-down faces than upright ones. faces with eyes closed rather than open.

Attractive faces than unattractive ones 

Research indicates that infants generally look at attractive faces for longer periods compared to unattractive faces.This is because the perception and preference for beauty is biologically hardwired and innate even in infants. Infants associate attractive faces as being more typically human compared to unattractive faces and thus stare longer at them.
