Aided conversations differ from spoken ones in their transitions between turns and symbols because seeking and choosing symbols takes more time than speaking words naturally. This study adopted the concepts and principles of conversation analysis (CA) to analyze the transitions between symbols during the construction of aided turns. The data was…

To identify the relationship between non-verbal working memory and graphic symbol selection, this study examined whether the response time to select target symbols in a sentence construction task differed between two groups: a high non-verbal working memory group and a low non-verbal working memory group. The interaction effect between non-verbal…

The general education classroom is filled with academic vocabulary, and individuals with developmental disabilities benefit from explicit vocabulary instruction (Browder et al., 2008; Marzano, 2020; Smith et al., 2013). Picture-based alternative and augmentative communication (AAC) can encourage academic skills development (Ahlgrim-Dehzel et al.,…

This study examined the changes in the communication skills of preschool students with autism spectrum disorder (ASD) that resulted from an intervention that featured three evidence-based, transactional approaches to augmentative and alternative communication (AAC) intervention: (a) attributing communicative meaning to student behaviours; (b)…

The aim of this study was to examine how early symbolic forms (and their associated communicative functions) are related to change in communication among a sample of 12 young children with autism spectrum disorder (ASD) who produced two or fewer spoken words ("M" age = 28.75 months; 11 male, 1 female). Parents reported on children's…

Forty 3-year-olds learned either 12 standard Blissymbols (SBS) or their enhanced forms (EBS). Results demonstrated that the subjects learned EBS faster than SBS, remembered more EBS than SBS, did not differ in the communicative use of SBS and EBS, and were affected more negatively when presented with the untrained SBS than EBS.

The word-learning ability of 12 school-age subjects with moderate or severe mental retardation was assessed. Subjects used the System for Augmenting Language with visual-graphic symbols for communication. Ability to fast map novel symbols was found to relate to symbol achievement status. Implications for vocabulary acquisition by youth with mental…

This article reviews research on the role of symbolic, referent, and instructional variables on the acquisition of augmentative and alternative communication (AAC) symbols by individuals with autism and severe speech and language impairments. Two vignettes illustrate findings of the review. (Contains references.) (Author/DB)
