MossTalk Training for Word Retrieval: Generalization Across Semantic Categories

Little is known about the independent usefulness of MossTalk Words, a computerized training program for word retrieval, nor how training effects generalize to other untrained words. In a single-participant design, we investigated effects of independent training with MossTalk multi-mode matching exercises in four individuals with stroke-induced aphasia. Three of four participants improved in picture naming for trained words. One showed limited generalization to words in untrained semantic categories. Three improved in standardized testing, particularly for auditory comprehension, which is addressed in the matching exercises. Improvements are possible with independent training programs such as MossTalk Words
