Purpose Children with autism spectrum disorder (ASD) and complex communication needs are increasingly taught to use tablet-based speech-generating devices (SGDs). An important issue in designing such interventions is the selection of an appropriate format for displaying vocabulary. The purpose of this study was to determine (a) whether young children with ASD can be taught to use different SGD vocabulary display formats and (b) whether there are differences across the formats on a range of secondary measures (e.g., preference and generalization). Method Five preschoolers with ASD (and prior experience with simpler aided augmentative and alternative communication) were taught to use grid and visual scene display SGDs during a play-based intervention. Acquisition of functional responding was assessed using a single-case experimental design. Secondary variables included error types, antecedents for communication, preference, and generalization. Results All participants increased their use of functional target vocabulary using both the grid and the simple visual scene display. Of the five participants, three showed similar performance with both formats, whereas two had slightly higher rates of functional responding with the grid. Individualized differences across participants and formats were apparent across secondary variables (e.g., preference, error types, generalization). Conclusions Both simple grid and visual scene displays may be viable options when teaching functional use of SGDs to children with ASD who have prior aided augmentative and alternative communication experience. Analyzing secondary variables beyond device acquisition (e.g., generalization, preference) may have implications for individualizing intervention.

Autism spectrum disorders (ASDs) are complex neuro-developmental disorders. They demonstrate pervasive deficits in social communication, restricted and repetitive behaviors, cognitive impairments, etc. Most often individuals with ASDs are often considered “non-verbal” and they require comprehensive intervention to improve their functional communication skills. Augmentative and alternative communication (AAC) was always viewed as a “last resort” for people with complex communication needs when all other interventions failed to achieve the potential benefit. However, with growing evidence, AAC has been implemented even in children with communication difficulties to augment spoken language development. Thus, this chapter aims to discuss the characteristics of ASD, to describe the need for AAC intervention in children with ASD, challenges and practices of AAC in ASD, to review implementation of aided AAC systems for children with ASD in different contexts, to indicate the gaps and future prospective in AAC intervention for people with ASDs.

Adolescents with autism spectrum disorder (ASD) often require support both for learning new skills and for communication. This study used a multiple baseline across activities design to evaluate the effect of videos with integrated visual scene displays (video VSDs), presented using a tablet-based app, on the percentage of steps completed independently within vocational training tasks by an adolescent with ASD and complex communication needs (CCN). Using the video VSDs, the participant met the mastery criterion for completing three tasks (including participation in communication exchanges) in a vocational setting. The results provide evidence that video VSDs may provide an effective support both for learning new skills in vocational contexts, and as a method of augmentative and alternative communication for individuals with ASD and CCN.

People with ASD often need to access AAC in situations where a tabletop digital device is not practical. Recent advancements have made more powerful, portable, and affordable communication technologies available to these individuals. Proloquo2Go is a new portable augmentative and alternative communication system that runs on an iPhone or iPod touch and can be used to meet the diverse needs of individuals with autism spectrum disorders (ASD) who are ambulatory and have difficulty using speech to meet their full daily communication needs. This article examines Proloquo2Go in light of the best practices in AAC for individuals with ASD such as symbols, visual supports, voice output, and inclusion.

Purpose Technology features that maximize communicative benefit while minimizing learning demands must be identified and prioritized to amplify the efficiency and effectiveness of augmentative and alternative communication (AAC) intervention. Picture symbols with paired text are a common representation feature in AAC systems for children with autism spectrum disorder (ASD) who are preliterate, yet little research about their comparative benefit exists. Method Four school-age children with ASD and limited speech who were preliterate participated in two single-subject studies. In one study, communication of high imageability words (e.g., nouns) on an AAC app during a book-reading activity was compared across two representation conditions: picture symbols with paired text and text only. In the second study, communication of low imageability words (e.g., verbs) was compared. Both studies had baseline, intervention, generalization, and maintenance phases. Results Prior to intervention, participants communicated across both representation conditions at low rates except two participants who were relatively successful using picture symbol with paired text representations of high imageability words. In response to intervention, all participants demonstrated increases in communication across representation conditions and maintained the increases. Participants demonstrated generalization in the text-only representation condition. Conclusions Children with ASD who were preliterate acquired communication at comparable rates regardless of whether an AAC app utilized picture symbol with paired text or text-only representation. Therefore, while larger scale research is needed, clinicians and technology developers could consider increasing the use of text in AAC representation given the inherent value associated with learning to recognize written words.

Many factors are important when planning and implementing strategies for teaching in the multiple disability/cross-categorical classroom. No two students' needs are alike; however, two areas are invariably a topic of discussion and lead many of the decisions being made in the individual's educational program: communication and presumed competence. The following chapter includes student narratives for a child with multiple disabilities as well as a child with autism spectrum disorder. Each child exhibits a significant communication delay and is considered to be non-verbal. The narratives along with strategies used to support the students have been included. Common misconceptions about augmentative and alternative communication use and presumed competence among students with significant communication needs are examined as well as research and theory concerning these areas.

Purpose The purpose of this study was to explore how speech-language pathologists (SLPs) who are augmentative and alternative communication (AAC) specialists approach the assessment process for 2 case studies, 1 child with cerebral palsy and 1 with autism spectrum disorder. The aim of the study was to answer the following questions: (a) How do clinicians with expertise approach the AAC assessment process for children with developmental disabilities? (b) Can any initial hypothesis be drawn about how SLPs approach the assessment of children with motor versus social interactive deficits? Method This study used a phenomenological qualitative design. The researchers conducted 2 in-depth, semistructured interviews with 8 SLPs who specialized in AAC and self-identified as primarily working with children. Results Four major themes emerged from the data: area of assessment, method of assessment, evaluation preparation, and parent education. Each major theme contained multiple subthemes and categories within those subthemes. Conclusions Participants discussed similar areas of assessment for both cases, indicating that some aspects of AAC assessment are universal. However, the specific aspects of what they were assessing and how they went about assessing them differed between the 2 cases. The results of the current study provide an outline of an assessment protocol for children with complex communication needs.

Augmentative and alternative communication (AAC) systems can support communication skills for people with significant developmental disabilities who experience complex communication needs (CCNs). There is a need to tailor best practices in AAC assessment and intervention to create individualized communication systems with this population. In this article, we outline the important components of AAC systems that can be implemented in authentic settings. However, given the limited evidence on AAC interventions specific to people with CCNs, we also identify some priority areas for future inquiry. Among these involve strategies to enhance decision making regarding (a) matching communication mode(s) to learner skills and contextual demands, (b) identifying communicative opportunities and obligations, (c) individualizing aided communication display features, (d) selection of vocabulary specificity, and (e) considering dosage parameters needed to acquire and maintain a communicative repertoire. In addition, we briefly discuss the use of telehealth to enhance intervention capability.

Purpose Three children ages 3;6 to 5;3 with developmental and language delays were provided experience with a traditional grid-based display and a contextually organized visual scene display on a speech-generating device to illustrate considerations for practice and future research in augmentative and alternative communication assessment and intervention. Method Twelve symbols were taught in a grid display and visual scene display using aided input during dramatic play routines. Teaching sessions were 30 minutes a day, 5 days a week for 3 weeks. Symbol comprehension and use was assessed pre and post 3 weeks of experience. Results Comprehension of symbol vocabulary on both displays increased after 3 weeks of experience. Participants 1 and 2 used both displays largely for initiation. Participant 3 had limited expressive use of either display. Conclusions The methods used in this study demonstrate one way to inform individual differences in learning and preference for speech-generating device displays when making clinical decisions regarding augmentative and alternative communication supports for a child and their family. Future research should systematically examine the role of extant comprehension, symbol experience, functional communication needs, and the role of vocabulary type in the learning and use of grid displays versus visual scene displays.

Objective: This meta-analysis reviews the literature on communication modes, communicative functions, and types of augmentative and alternative communication (AAC) interventions for school-age participants with autism spectrum disorders and/or intellectual disabilities who experience complex communication needs. Considering potential differences related to outcomes that were targeted for intervention could help identify the most effective means of individualizing AAC interventions. Methods: We performed a systematic literature search using Academic Search Ultimate, ERIC, PsycINFO, Web of Science, and Proquest Dissertations & Theses Global to retrieve research conducted between 1978 and the beginning of 2020. Studies included in the synthesis are (a) in English; (b) has one or more participants with an intellectual delay, developmental disability(ies); (c) reported the results of an augmentative and alternative communication (AAC) intervention to supplement or replace conventional speech for people with complex communication needs; (d) was a SCED; (e) measured social-communicative outcomes. We synthesized results across studies using multi-level meta-analyses of two case-level effect size metrics, Tau and log response ratio. We conducted moderator analyses using meta-regression with robust variance estimation.Results: Across 114 included studies with 330 participants and 767 effect size, overall Tau effects were moderate, Tau = 0.72, 95% CI [0.67, 0.77], and heterogeneous. For the subset of data series where log response ratio could be estimated, the overall average effect was LRR = 1.86, 95% CI [1.58, 2.13], and effects were highly heterogeneous. There were few statistically significant differences found between moderator categories, which included communication mode, communicative function, and type of AAC implemented.Conclusions: This meta-analysis highlights the potential differences related to outcomes that were targeted for AAC interventions for individuals with ASD and IDD. AAC intervention has been shown to improve communication outcomes in this population. However, there was a lack of sufficient data to analyze for some potential moderators such as insufficient descriptive information on participant characteristics. This is likely due to the heterogeneity of the participants and implementation factors; however, these factors were frequently underreported by original study authors which disallowed systematic analysis. That said, there is a need for more detailed participant characteristic descriptions in original research reports to support future aggregation across the literature. Sponsorship: We received funding for the review from the Institute of Education Sciences.Protocol: The review protocol was registered in the PROSPERO system (CRD42018112428).
