Naturalistic teaching approach to develop spontaneous vocalizations and augmented communication in children with autism spectrum disorder

Abstract

Naturalistic developmental behavioral interventions (NDBI) have been shown to facilitate the development of spontaneous language in individuals with speech and language impairment. Several meta-analyses have reported a small number of studies that utilized naturalistic teaching approaches combined with augmentative and alternative communication (AAC) interventions to develop requesting skills in individuals with autism spectrum disorder (ASD). Therefore, the main purpose of this study was to determine whether a natural language paradigm (NLP) and time delay is effective in expanding vocal and augmented requesting skills in three children with ASD between the ages of 4 and 6 years. A concurrent multiple baseline design across participants was used to evaluate the effectiveness of the intervention. The results of the study demonstrated that the participants were successful in emitting vocal requests when both modalities were available and NLP combined with time delay was effective in increasing spontaneous vocal requests in all participants.
