Effects of T2L on single-word reading of individuals with ASD (Caron et al., 2021)

Caron, J., Light, J., & McNaughton, D. (2021). Effects of a literacy feature in an augmentative and alternative communication app on single-word reading of individuals with severe autism spectrum disorders. Research and Practice for Persons with Severe Disabilities, 46(1), 18–34. https://doi.org/10.1177/1540796921992123


The Current Study: The purpose of this study was to investigate the effects of an augmentative and alternative communication (AAC) app with transition to literacy (T2L) software features (i.e., dynamic text and speech output upon selection of a graphic symbol within the grid display) on the acquisition of 12 personally relevant single words for individuals with severe autism spectrum disorder (ASD) who had minimal or no speech. The study implemented a single-subject, multiple-probe, across word sets design with four participants.

Results and Clinical Implications: All four participants in this study demonstrated increased accuracy reading targeted single words. Results from this study provide preliminary evidence that the T2L features can positively affect the single-word learning of individuals with ASD who have minimal speech and limited literacy skills.

Redesigning AAC apps with T2L features results in improvements in single-word reading for individuals with severe ASD who have minimal or no speech and who have had limited literacy opportunities or success.
