The understanding of self based on facial information may emerge earlier than that based on other body parts because the face is often regarded as the primary physical embodiment of self, at least for adults. Although researchers have hypothesized that the level of understanding of self differs with age, the idea that self differs with body parts has not been examined. This study investigates whether the understanding of self in infancy differs with respect to body parts by simultaneously showing infants a live and three-second delayed video of their own face or legs. The results confirm that infants prefer the delayed feedback of their own face. However, a specific preference is not observed when their own legs are displayed, indicating a developmental gap in the self-perception of body parts.
