Abstract

This paper provides an integrated review of the current literature in this area, suggests future research directions, and delineates clinical and educational implications. The integration of behavioral and technological advances in the AAC field provides an optimistic outlook for the future development of functional communication systems for persons with severe intellectual disabilities.
