The present study investigated the learning demands of dynamic display augmentative and alternative communication (AAC) technologies that differed in system layout and menu page approaches for 3-year-old children. Ten typically developing children were randomly assigned to each of 3 technology approaches and were asked to located vocabulary items within a play context. Results indicated that the children had difficulty with all of the technologies on initial exposure. After the 1 st learning session, children performed significantly better with AAC technologies in a contextual scene format than in a grid format. Some limited generalization to new vocabulary was evident. AAC technologies for young children need to be redesigned to better reflect the developmental models of children. Results are discussed with implications for practice and suggestions for future research.
