A Scoping Review of Aided AAC Modeling for Individuals With Developmental Disabilities and Emergent Communication

Purpose of ReviewAided AAC modeling is an umbrella term for when communication partners model language on an aided AAC system to support an individual's comprehension and/or communication development. This scoping review aims to provide an overview of aided AAC modeling studies targeting individuals with emergent communication and describing features and findings from these studies.Recent FindingsResearch on interventions that includes aided AAC modeling is growing. Recent studies cover interventions for individuals that previously were excluded, such as individuals who use alternative access methods to select symbols.A search yielded 29 studies that encompassed a total of 237 participants using emergent communication. Positive outcomes from the aided AAC modeling interventions were reported in the majority of the studies. In future research, a clear description of the different components of the interventions and their expected effect on the outcome may assist in comparing the effect of different types of aided AAC modeling interventions.
