Even with little exposure to cultural standards of beauty, “infants treat attractive faces as distinctive regardless of the sex, age and 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.
