Identification of intentional communication in students with severe and multiple disabilities

The use of published criteria to determine the intentionality of communicative behaviors of individuals with severe and multiple disabilities is discussed in light of research with individuals with and without intellectual disability. Data were collected from four young students with severe intellectual and physical disabilities in addition to sensory deficits. Communicative sampling procedures were used to explore how behaviors other than co-ordinated attention may signal emerging intentionality. These behaviors, which included persistence, idiosyncratic behaviors, and modifications to signals, in addition to patterns of differential modality use, are discussed as potential indicators. Implications for the identification and development of intentional communication in children with severe and multiple disabilities are discussed, along with directions for future research.
