Auditory evoked responses (AERs) were recorded from left and right hemispheres of 11 male preterm infants (mean conceptional age 35.9 wks) in response to synthesized speech syllables and their nonphonetic and nonspeech analogs. Discrete components of the scalp-recorded AERs to these different stimuli were isolated and identified. One component reflected the presence of a left hemisphere mechanism that was sensitive to differences in phonetic and nonphonetic transitional characteristics. Other components of the AER were identified as sensitive to hemisphere differences and formant bandwidth changes. (18 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
