Previous studies of face perception during early infancy are difficult to i
nterpret because of discrepant results and procedural differences. We used
a standardized method based on the Teller acuity card procedure to test new
borns, 6-week-olds, and 12-week-olds with three pairs efface and nonface st
imuli modified from previous studies. Newborns' preferences were influenced
both by the visibility of the stimuli and by their resemblance to a human
face. There appears to be a mechanism, likely subcortical, predisposing new
borns to look toward faces. Changes in preferences at 6 and 12 weeks of age
suggest increasing cortical influence over infants' preferences for faces.
