Researchers showed these patterns one at a time to newborns who were only a few minutes old. Although they had yet to see their first real face, the newborns preferred to look at the pattern that most resembled the arrangement of the human face.
Tracking their eye movements, you can see that 1-month-old infants spend most of their time looking at external features of the face – mostly the chin and outer hairline. By 2 months, infants are now looking more at the internal features, especially the eyes and mouth.
This graph shows hypothetical data from work with a 4-month-old infant using the habituation–dishabituation technique. The infant shows habituation by looking less and less at a red circle that is presented repeatedly—but looking time increases (dishabituation) when novel forms or colors are presented.
Researchers use the preferential-looking technique to determine which set of stripes infants differentiate from the plain gray square.
