ABSTRACT
The ultimate goal of our many years of research was to improve clinical intervention for children with language disorders. To reach this goal, we not only studied language-disordered children but also those who were normal, congenitally deaf, or blind. We also studied adult patients with acquired brain damage. We claimed that developmental data collected on the different groups of children should fit a common model of development and also apply to the behavior of persons with acquired brain damage. This common model then should foster intervention programs for children with developmental language disorders and for adults with acquired or degenerative diseases of the nervous system.
