Thistle Poster Session Thistle, J., & Wilkinson, K. M. (2011, November). Working Memory and attention in utilizing aided AAC displays. Presentation at the Annual Conference of the American Speech-Language-Hearing Association, San Diego, CA. [Poster]

AAC gives individuals with intellectual/developmental disabilities a voice. In place of spoken words, users of aided AAC rely on objects, pictures, or written words to convey messages. For many, this use of aided AAC to represent linguistic concepts relies heavily on the visual modality.

We examine the working memory and attention demands of aided AAC used by individuals with intellectual/developmental disabilities. Analysis of a prominent working memory model and data from recent research provide initial guidance regarding the consideration of visual characteristics of a display and how these characteristics may influence the demands of AAC.Jenn Thistle and Krista WIlkinson
