Even with little exposure to cultural standards of beauty, “infants treat attractive faces as  distinctive regardless of the sex, age a nd race of the stimulus(刺激物) faces,”  write psychologist Judith H.Langlois and her colleagues in the January DEVELOPMENTAL PSYCHOLOGY.

In their experiment, 5 healthy 6-month-old infants from middle-class families viewed slides showing eight pairs of white male faces and eight pairs of white female faces. Each pair, displayed for 10 seconds, consisted of one attractive and one unattractive face, as previously judged by a group of male and female college students. An experimenter viewed the young participants on a video monitor and recorded the direction and duration of each infant’s gaze.

The 35 boys and 25 girls looked longer at both male and female faces judged as attractive, the researchers found.

Their second study of 6-month-old involved 15 boys and 25 girls, mostly white, who saw eight pairs of slides showing an attractive and an unattractive black female, as previously judged by both white and black college students.  Again, the babies looked much longer at attractive faces.  

Finally, 19 boys and 20 girls, all 6 months old and almost all of them white, viewed eight pairs of slides showing the faces of 3-month-old boys and girls previously rated as attractive or unattractive by college students. Attractive baby faces drew signficantly longer looks, the psychologists report.

Further studies must explore whether infants take attractive faces as “best examples” of a face, the investigators claim Langlois and a coworker recently reported that attractive faces may possess features that approximate the mathematical average of all faces in particular population.
