AAC and scripting activities to facilitate communication and play

Abstract

Many children with developmental disability have limited skills in both play and communication. In this study, the effects of a naturalistic intervention approach to play and symbolic communication was investigated within a single-subject multiple baseline design. The intervention involved scripting play activities and modelling vocabulary in speech and the augmentative and alternative communication (AAC) modality of sign. An additional intervention phase was introduced, wherein the AAC intervention was expanded to include an electronic communication device. The results indicated that modelling and scripted play activities resulted in increases in symbolic play, while changes in types of functional play were evident, while its frequency was somewhat erratic across base-line and intervention phases. Improvements in communication were more evident when a multimodal AAC approach was used in modelling than when sign was used alone.
