The purpose of the presentation was to give an overview of a couple of studies examining neurophysiological, cognitive and linguistic development in deaf and hearing-impaired children (5–7 years of age) with CI and/or hearing aids and how a phonological intervention programme may influence this development. The deaf and hearing-impaired children were compared with age-matched hearing children. The results reveal that deaf and hearing-impaired children had equivalent or close to equivalent performance levels compared to hearing children for cognitive and linguistic tasks with relatively low demands on phonological processing, whereas there was a substantial and significant difference between the groups for cognitive tasks involving explicit phonological processing. The results indicate that there is a relationship between age at implant and neurophysiological, cognitive and linguistic development, where early implantation promotes faster development. The childrens´ cognitive performance increased as a function of phonological intervention.

For further information on cognitive development in deaf children with cochlear implants, there are links to three doctoral theses that I have supervised, that all deals with cognitive and linguistic development in deaf children with CI (Björn Lyxell).
