Abstract
This paper describes early language development in a deaf Spanish child fitted with a cochlear implant (CI) when she was 1;6 years old. The girl had been exposed to Cued Speech (CS) since that age. The main aim of the research was to identify potential areas of slow language development as well
as the potential benefit of CI and CS. At the beginning of this research the child was 2;6 years (she had been using the CI for 12 months). Adult–child 30-minute sessions were videotaped every week for 1 year (13–24 months of CI use), and transcribed according to CHAT norms. Measures of phonemic inventory, intelligibility, lexicon, and grammar development were obtained. Part of the data were compared with data from two normally hearing (NH) children with the same mean length of utterance (MLU). In order to confirm trends observed during these 12 months of observation, an extra set of data was obtained in the next 3 months (25–27 months of CI use). Results in the initial 12 month period (13–24 months of CI use) showed irregular language development in the deaf child. The development of her phonemic inventory and lexicon progressed at a rate that was similar to, or faster than, that of NH children. However, the slow acquisition of articles and also the slow development of MLU suggested that the child might have problems with grammar. Data from the next 3 months (25–27 months of CI use) confirmed this trend. Results are discussed in relation to similar studies in other languages. Potential benefits of CS are also discussed.
Conclusion
Based on the findings from this study, the authors would like to make some points regarding the role of language habilitation for CI children. In the last 15 years, many researchers and professionals have correctly emphasized the important benefits of CI. Such emphasis may make some parents and even language therapists complacent regarding the role of language training in the post-operative habilitation programme of their child. That is, they may assume that the CI will do all the hard work, particularly since the use of the implant has such a positive impact on things such as child attention, phonology, intelligibility, or vocabulary acquisition—areas of development which are most apparent for parents of pre-school children. However, problems such as agreement errors or slow development of MLU might not attract the parents’ or even the therapists’ attention until it is too late for them to ever develop normally. Further research in this area is thus required to provide language therapists and parents with realistic descriptions of the problems faced by the new deaf population. Furthermore, professionals should provide parents with advice based on realistic descriptions of the advantages and limitations of CI.
