Integrating the multisensory features of talking faces is critical to learn and extract coherent meaning from social signals. In the present study, we provide neurophysiological evidence for a developmental decline in cross-species face-voice matching. We measured event-related brain potentials (ERPs) while 4- and 8-month-old infants watched and listened to congruent and incongruent audiovisual presentations of monkey vocalizations and humans mimicking monkey vocalizations. The ERP results indicated that younger infants distinguished between the congruent and the incongruent faces and voices regardless of species, whereas in older infants, the sensitivity to multisensory congruency was limited to the human face and voice.
