Abstract:
This research describes the development of communicative intention of young children with cochlear implants in order to study the relationship between the early communicative intention of these children and their later verbal communication. Five children under the age of three years with cochlear implants were selected from the records of the University of Stellenbosch, Tygerberg Academic Hospital’s Cochlear Implant Unit, Cape Town as subjects. Video recordings of each of the five subjects in unstructured free play interaction with their caregivers, before cochlear implantation and each six months after cochlear implantation over a period of two years were used to identify the development of their communicative intention. The Communicative Intention Inventory (Coggins&Carpenter, 1981) was used to classify the communicative behaviour of the subjects according to the types of communication functions that were used, as well as the way in which they expressed the functions of communication. Results of the study show that the development course of the functions of communication that the subjects used over a two-year period, were consistent with the development patterns found in younger children with normal hearing. There was however marked individual differences between the subjects during the transition from nonverbal to dominantly verbal ways of communication as far as the rate of development of verbal communication was concerned. A strong relationship was found among the five subjects regarding the use of the nonverbal communication functions, request for object or action and protest before cochlear implantation and their total verbal communication two years after cochlear implantation, which could account for these individual differences in the rate of verbal communication development after cochlear implantation. Indications for clinical application and future research were identified on the basis of these conclusions. The data collected during the research is seen as meaningful in clinical decision-making regarding the suitability of young children under the age of three years with a profound hearing loss for cochlear implantation and their therapeutic management.
