Variations on the written choice communication strategy for individuals with severe aphasia

The Written Choice Communication Strategy is an augmentative and alternative communication (AAC) technique designed to enhance the quality and efficiency of communication for people with severe aphasia. This paper presents the results of a study employing an alternating treatment design to examine the relative contributions of auditory and visual information to the Written Choice process. In three conditions (auditory only, visual only, and standard Written Choice), subjects responded to questions regarding Norman Rockwell pictures. Results revealed different accuracy patterns for each subject across the three conditions. Implications for applying AAC strategies to the treatment of severe aphasia are discussed.
