Abstract

Behavioral and cardiac responses were assessed for 3-month-old infants placed face-to-face with a mirror and peer. Infants looked longer at the mirror, but smiled, vocalized, reached toward and squirmed more in the presence of an infant peer. In addition, tonic heart rate was elevated during the peer situation. These effects may relate to the peer situation being more stimulating or arousing. Differential responding to the mirror and peer suggests some very early awareness of differences between a self-image and another infant.
