Teaching Bilingual Features To A Young Augmentative And Alternative Communication User With Autism

This study examines how a minimally verbal, young Spanish-English bilingual child with Autism Spectrum Disorder (ASD) uses translanguaging toggle features on an Augmentative and Alternative Communication (AAC) device to produce multi-word picture descriptions. The study employed a Rapidly Alternating Treatments Design (RATD) to analyze AAC performance under language-controlled Spanish-only and English-only conditions. A quantitative analysis examined the frequency and patterns of bilingual AAC feature use during aided modeling and instruction, while qualitative methods explored the related challenges and benefits. This study highlights the potential for bilingual AAC systems to enhance communication effectiveness and underscores the importance of incorporating user and caregiver perspectives in developing culturally and linguistically responsive AAC interventions.
