Abstract:
Introduction: Profound hearing loss encounters children with delay in speech and language. As it is known language acquisition in young deaf children is a lengthy process, but cochlear implanted children have better spoken language skills than if they had not received the device. According to the importance of cochlear implant in deaf child's language development, this study evaluates the effect of different variables on child's language performance. Method and material: 45 cochlear implanted children were tested , all of whom had used the device for at least 2 years. In order to evaluate the children , the NEWSHA test which is fitted for Persian speaking children was performed and language development of the children was compared through stepwise discriminant analysis. Results: After evaluation of the effect of different variables like child's age of implantation, participating in rehabilitation classes, parent's cooperation and their level of education, we came to a conclusion that the child's age of implantation and rehabilitation program significantly develop the child's language performance. Discussion: The value of cochlear implant in improvement of deaf children in speech, language perception , production and comprehension is confirmed by different studies which have been done on cochlear implanted children. Also, the present study indicates that language development in cochlear implanted children is highly related to their age of implantation and rehabilitation program.

So, this study is done with the aim of the evaluation of the impact of child's age of implantation, participating in rehabilitation classes, parent's cooperation and their educational level on language development of 6 years old cochlear implanted children, who received the device at least 2 years before.
Results The main purpose of this study was to evaluate the expressive language development in cochlear implanted children based on their age of implantation, participation in class, learning ability, parent's level of education and cooperation.
To assess the effect of different variables like child's age of implantation, participation in rehabilitation classes, learning ability, parent's level of education and their cooperation, stepwise discriminant analysis was done .
0 Discussion Cochlear implants enable different degree of improvement for deaf patients in the areas of speech and language perception, production and comprehension depending upon the extent of their hearing loss and other variables (5).
