- Original description
The principal aim of this study is to evaluate the cortical developement of perceptual skills and executive functions over time, in children with cochlear implants aged 10-24 months and 3-7 years compared with normally hearing subjects (NHS). To do this, the investigator will use functional Near InfraRed Spectroscopy (fNIRS) during 4 tasks that engage the childs perceptual and cognitive skills over a period of 18 months. The performance scores obtained by each participants as well as the cortical activity will be analysed and decrypted.Read full original descriptionShow less
