Electrophysiological correlates of handedness and speech perception contrasts.
Auditory evoked responses (AERs) were recorded from left- and right-handed subjects who listened to consonant sounds from different phonetic categories. AERs recorded at parietal scalp regions indicated both groups differentiated categorical differences between speech sounds. However, hand preferences did not affect hemisphere responses to speech sounds.
