Auditory evoked responses (AER) were recorded from the temporal region of both cerebral hemispheres of human infants, children, and adults in response to four speech and two nonspeech acoustic stimuli. Left hemisphere AERs were larger in amplitude than right hemisphere AERs to speech stimuli for all groups. Nonspeech stimuli produced larger amplitude AERs in the right hemisphere. Lateral differences to both types of stimuli were found to decrease with age.
