Intensity significantly impacts aphasia treatment efficacy, yet research protocols have not answered questions about optimal intensity and/or dosage. A single-subject ABA design investigated the influence of repetition priming on naming performance for four individuals with stroke-induced aphasia. The participants completed an intensive training protocol with repeated attempts to name pictures. Independent variables included training status and stimulus dosage. The dependent variable was response accuracy. Response accuracy increased for all participants during the training phase, and training effects persisted through the maintenance phase for all participants. Stimulus dosage did not consistently influence response accuracy for the participants.
