An 18-year-old woman who was severely intellectually delayed and physically handicapped was taught a direct select color encoding strategy as a potential means of increasing the available vocabulary on her communication board. Teaching procedures involved the establishment of a chained matching-to-sample procedure. This procedure eventually resulted in the learner selecting a color, followed by the selection of an explicit symbol that corresponded to an object sample. The encoding was maintained and generalized to untrained exemplars. Implications for augmentative and alternative communication intervention are discussed.
