Little is known about infants' perception of cross-modal cues to identity, but the importance of recognizing familiar individuals makes it likely that this skill would be evident early in life. Infants 6-8 months of age were tested on their ability to link dynamic cross-modal cues to the identity of unfamiliar speakers and singers. After exposure to speech or singing, infants watched two silent videos, one featuring the previously heard speaker or singer. Infants looked significantly longer at the video of the person heard previously, which indicates that they can match auditory and visual cues to the identity of unfamiliar persons.
