Brief summary
In the past two decades, the selection criteria for cochlear implantation have been greatly relaxed so that about 60-70% of present cochlear implant (CI) candidates have significant residual hearing in their contralateral ear. However, contralateral hearing is often not considered in rehabilitation programs, mainly due to the lack of scientific evidence on the role it may play. The present project aims to better understand the mechanisms of perceptual learning of CI-processed speech after implantation and to develop and test rehabilitation strategies for CI users.
Interventions
PROCEDUREProgram A
Presentation of the sentence to the implant alone
PROCEDUREProgram B
Presentation of the sentence to the implanted ear, associated for the non-implanted ear
PROCEDUREControl
Presentation of the sentences alternately to the most recently implanted ear and both implanted ears at the same time
