This study compared 3- to 4-month-olds' recognition of previously unfamiliar faces learned in a mov-
ing or a static condition. Infants in the moving condition showed successful recognition with only 30 s
familiarization, even when different images of a face were used in the familiarization and test phase
(Experiment 1). In contrast, infants in the static condition showed successful recognition only when the
familiarization duration was lengthened to 90 s and when the same image was used between the famil-
iarization and test phase (Experiments 2 and 3). Furthermore, presentation of multiple static images of a
face did not yield the same level of performance as the moving condition (Experiment 4). These results
suggest that facial motion promotes young infants' recognition of unfamiliar faces.
Previous developmental studies show consistently
that motion information plays an important role
in infant visual perception (e.g., Kellman, 1984;
