Abstract

Cortical auditory evoked potentials were studied in responses to voice and environmental sounds in 4- to 5-year-old children. A specific response to voice was dissociated from the response to environmental sounds. It appeared as a positive deflection recorded at right fronto-temporal sites and beginning within 60ms of stimulus onset. We termed this response Fronto-Temporal Positivity to Voice (FTPV).
