The effect of age at time of cochlear implantation on the pragmatic development of the prelingual hearing impaired children

Abstract

BackgroundPragmatics is the social use of language that draws on understanding human interactions in specific contexts and requires engagement with a communicative partner or partners. The hearing-impaired children are known to have a pragmatic language delay as hearing impairment deprived of exposure to natural communication interactions, in addition to the language delay they have. Since the age of implantation has emerged as an important predictor of language, hearing, and speech in children who use cochlear implants (CI), question aroused about the benefits of early cochlear implantation on pragmatic language development in those children. Thus, this study aims to compare the pragmatic language development of the prelingual hearing impaired children who cochlear implanted before the age of 3 years and those who cochlear implanted after the age of 3 years.ResultsThe two study groups showed no significant differences regard their scores in the Egyptian Arabic Pragmatic Language Test (EAPLT). The two studied groups had pragmatic language scores below their 5th percentile. Among the studied groups, the scores of the EAPLT were positively correlated to the age of the children, the children’s language abilities, and the duration of the received language rehabilitation, with no significant correlation to the age of implantation.ConclusionsThe age of implantation has no impact on pragmatic language development in children with CI. The prelingual children with CI are susceptible to delays in the pragmatic language development that is primarily related to the age of those children and their language abilities, besides their experience in social interactions. These results should be considered in their rehabilitative plan and advocate the importance of early incorporation of pragmatic behaviors into their intervention programs.
