The purpose of this systematic review was to investigate the effects of instruction on single-word reading of individuals who use aided augmentative and alternative communication (AAC). A systematic search identified nine single-case experimental design studies that involved 24 individuals who used aided AAC. Overall, the evidence indicated that instruction had positive effects on reading at the single-word level for individuals across ages and diagnostic categories (i.e., autism spectrum disorder (ASD), cerebral palsy (CP), Down syndrome, and intellectual disability)...

Documented variability in augmentative and alternative communication (AAC) intervention outcomes makes it difficult for clinicians to select systems most likely to be effective for individual children with autism spectrum disorder (ASD). The aim of this study was to identify child-related factors associated with AAC intervention outcomes through a systematic review of the research literature. A search was conducted of peer-reviewed research articles in which AAC intervention outcomes and associated factors were reported for children with ASD...

Studies have investigated the use of eye-tracking technology to assess cognition in individuals with Rett syndrome, but few have looked at this access method for communication for this group. Loss of speech, decreased hand use, and severe motor apraxia significantly impact functional communication for this population. Eye gaze is one modality that may be used successfully by individuals with Rett syndrome. This multiple case study explored whether using eye-tracking technology, with ongoing support from a team of augmentative and alternative communication (AAC) therapists, could help four participants with Rett syndrome meet individualized communication goals...

The purpose of this meta-analysis was to summarize single-case intervention studies in which Functional Communication Training (FCT) involving augmentative and alternative communication (AAC) was implemented in school settings. Overall, the findings suggest that FCT involving AAC was effective in reducing challenging behaviour and promoting aided or unaided AAC use among participants with disability. FCT was more effective for the participants who engaged in less severe forms of challenging behaviour prior to intervention...

This comparative study is a replication and extension of previous work related to children's drawings of early concepts. In all, 15 children with autism spectrum disorder (ASD) and 19 children without disability took part in the study, and were video recorded as they drew 10 early emerging concepts such as "eat" and "more." In a second task, the participants were asked to label Picture Communication Symbols conventionally used in augmentative and alternative communication (AAC) systems. Descriptive, correlational, and inferential statistics were used to analyze the data...

Kelsey Mandak, Janice Light
This study used an online focus group to examine the beliefs and practices of school-based speech-language pathologists (SLPs) who served children with complex communication needs regarding their provision of family-centered services. Participants revealed that despite their desire for family involvement and reported beliefs in the importance of family-centered services, there were barriers in place that often limited family-centered service provision. Across the SLPs, many were dissatisfied with their current provision of family-centered services...

Narratives are a pervasive form of discourse and a rich source for exploring a range of language and cognitive skills. The limited research base to date suggests that narratives generated using aided communication may be structurally simple, and that features of cohesion and reference may be lacking. This study reports on the analysis of narratives generated in interactions involving aided communication in response to short, silent, video vignettes depicting events with unintended or unexpected consequences...

The facility to describe scenes and events is important in everyday communication, but little is known about the description skills and strategies of young people using aided communication. This article explores how 81 children and adolescents using aided communication and 56 peers using natural speech, aged 5-15 years, described pictured scenes and events presented on video to a partner who had no prior knowledge of the content. The group who used aided communication took longer and included fewer elements in their descriptions than the reference group; however, the groups did not differ in their use of irrelevant or incorrect elements, suggesting that both groups stayed on topic...

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...

Children with severe motor impairments are restricted in their manipulation and exploration of objects, but little is known about how such limitations influence cognitive development. This study investigated visual-constructional abilities in 75 children and adolescents, aged 5;0-15;11 (years;months), with severe speech impairments and no intellectual disabilities (aided group) and in 56 children and adolescents with typical development (reference group). Verbal comprehension, non-verbal reasoning, and visual-spatial perception were assessed with standardized tests...

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...

There is limited knowledge about aided language comprehension and use in children who use aided communication and who are considered to have a relatively good comprehension of spoken language. This study's purpose was to assess their aided language skills. The participants were 96 children and adolescents who used communication aids (aided group) and 73 children and adolescents with natural speech (reference group), aged 5 to 15 years. All of the participants who used aided communication were regarded by their teachers or professionals as having age-appropriate language comprehension...

Parents and professionals who work with individuals who use augmentative and alternative communication (AAC) face tremendous time pressures, especially when programming vocabulary in AAC technologies. System design (from programming functions to layout options) necessitates a range of skills related to operational competence and can impose intensive training demands for communication partners. In fact, some AAC applications impose considerable learning demands, which can lead to increased time to complete the same programming tasks...

This study examined eye movements during a visual search task as well as cognitive abilities within three age groups. The aim was to explore scanning patterns across symbol grids and to better understand the impact of symbol location in AAC displays on speed and accuracy of symbol selection. For the study, 60 students were asked to locate a series of symbols on 16 cell grids. The EyeLink 1000 was used to measure eye movements, accuracy, and response time. Accuracy was high across all cells. Participants had faster response times, longer fixations, and more frequent fixations on symbols located in the middle of the grid...

Speech-language therapists (SLTs) have direct contact with a wide variety of individuals who require augmentative and alternative communication (AAC) and they are therefore considered to have a primary role in the assessment, selection, and implementation of AAC symbols, techniques, aids, and strategies. Limited information is available with regard to SLTs' practices in the field of AAC, and there is a particular paucity of information about developing country contexts such as South Africa. The aim of this study was to determine how South African SLTs perceive their current AAC practices...
