Augmentative and Alternative Communication on Autism Spectrum Disorder: Impacts on Communication.

Purpose: To verify the effects of the Speech-Language Intervention with Augmentative and Alternative Communication (AAC) in communicative acts in children with Autism Spectrum Disorder (ASD).

Method: This is a longitudinal case-study design involving three subjects attended in a Speech-Language Pathology (SLP) Clinic School. Primary data were obtained from the observation of recorded videos of pre and post-intervention therapist assessment sessions with each child in play activities, while secondary data come from interviews with parents.

Communication aid provision and use among children and adolescents developing aided communication: an international survey.

A fundamental requirement of a supportive language development for young children who need aided communication is that an aided communication system is made available and its use is supported. There is limited information about the age at which children are typically provided with a communication aid or about how aided communication is used in everyday situations. Using questionnaire-based interview data, this study investigated (a) the pattern of provision of communication aids to 84 children and adolescents, (b) parents' and professionals' evaluation of the quality of communication across contexts, and (c) availability and use of aided communication in these contexts.

Vocabulary comprehension and strategies in name construction among children using aided communication.

Vocabulary learning reflects the language experiences of the child, both in typical and atypical development, although the vocabulary development of children who use aided communication may differ from children who use natural speech. This study compared the performance of children using aided communication with that of peers using natural speech on two measures of vocabulary knowledge: comprehension of graphic symbols and labeling of common objects. There were 92 participants not considered intellectually disabled in the aided group.
