ABSTRACT
This article presents the contributions of using a high-tech Augmentative and Alternative Communication (AAC) system in the development of the communication skills of a child with Autistic Spectrum Disorder (ASD). For this, a case study was carried out with a two-year-and-two-month-old child during 24 therapy sessions over 8 months. As assessment instruments, the Autism Treatment Evaluation Checklist (ATEC) and the protocol for Communication Assessment in Autism Spectrum Disorder (COATEA) were used. During the interventions, the Development of Communication Skills in Autism (DCSA) method was used and, as an AAC resource, the high-tech board from the aBoard app. Postintervention results showed improvements in the scores of the evaluation instruments for skills of expression, comprehension, and social interaction. The child’s vocabulary also increased, with the acquisition of new lexical categories; initiative to request objects beyond his visual reach with the AAC; and better social communication in the family and educational context. The results point to contributions of the use of a high-tech assistive system of AAC in the development of communication skills of a child with ASD.
