Abstract
This study is related to the paper 'Functional communication in blind multiply-impaired children' (Dean and Aitken, 1986). The difference is that this is a single case study and that the child concerned is much younger. Results show marked improvement over those of the previous study. The criteria of evaluation suggest that the factor responsible for improvement was the specific intervention. The results have implications for intervention, assessment and theories of the nature o f language acquisition.
