RESUMEN
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.

We taught three typically developing siblings to occasion speech by implementing the Natural Language Paradigm (NLP) with their brothers with autism spectrum disorder (ASD). A non-concurrent multiple baseline design across children with ASD and sibling dyads was used. Ancillary behaviors of happiness, play, and joint attention for the children with ASD were recorded. Generalization of speech for the children with ASD across setting and peers was also measured. During baseline, the children with ASD displayed few target speech behaviors and the siblings inconsistently occasioned speech from their brothers. After sibling training, however, they successfully delivered NLP, and in turn, for two of the brothers with ASD, speech reached criterion. Implications of this research suggest the inclusion of siblings in interventions.
