Central auditory discrimination in children with congenital hearing loss
What is it about?
Congenital deafness not only delays auditory development but also hampers the ability to perceive nonspeech and speech signals. We found the waveforms and topographic features of early, middle, and late components evoked by nonspeech and speech signals in passive auditory event-related potential (ERP) in children with and without hearing loss. The ERP components are candidates for objective indicators of auditory learning and development for children with hearing loss.
Why is it important?
The dynamic changes among auditory ERP components provide evidence supporting a child’s ability to use cues to discriminate nonspeech and speech. The early, middle, and late components of auditory ERP are a promising tool for investigating nonspeech and speech perception and discrimination in future studies.
