An Exploration of Multimodality in Augmentative and Alternative Communication

Abstract

The aim of this paper was to trace the evolution of how multimodality has been considered in the field of augmentative and alternative communication (AAC) and the potential implications for clinical practice. Early reference to the notion of multimodality appeared to reflect concerns about AAC decision-making that resulted in recommendations for single modality systems and the exclusion of people from AAC interventions. Providing people with AAC, regardless of their underlying symbolic capacity, has been a reaction to the rejection of a candidacy model and the adoption of the participation model. However, a potential danger may arise from expecting individuals who are pre-intentional to acquire symbolic skills. In line with the participation model, AAC can be used appropriately for these individuals for mediating responses from people in their social environments, while providing opportunities for symbol communication.

Notes

1 The distinction between pre-intention and unintentional is made to reflect a developmental trajectory to intentional and symbolic assumed likely for children, but less so for adults who have not demonstrated that progress, unless access to AAC allows demonstration of underlying symbolic competence.
