Core vocabulary is defined as "lexical items that are accepted as being central and indispensable to language use" (Bell, 2012, p. 1). Use of core vocabulary is common amongst professionals who teach augmentative and alternative communication (AAC) to individuals with disabilities. Although the use of AAC is often classified as an…

The purpose of this review was to assess the effectiveness of tablet-based speech-generating devices (SGDs) in improving communication skills for individuals with autism spectrum disorder (ASD). A total of 31 single-case design intervention studies involving 84 individuals with ASD were reviewed and included in the analysis. We calculated Tau-U to…

Communication deficits are one of the core symptoms of autism spectrum disorder (ASD), and augmentative and alternative communication (AAC) systems are utilized to facilitate the communication and language development of children with ASD. This review examines the research literature on the use of aided and unaided AAC systems in interventions for…

This meta-analysis reviews the literature on communication modes, communicative functions, and AAC type examined during interventions with school-age participants with ASD and/or ID who experience CCN. Considering potential differences related to outcomes taught could help identify the most effective means of individualizing AAC interventions. We…

This systematic review evaluated the effect of speech interventions with the addition of speech generating devices on vocalizations of children with autism spectrum disorder (ASD) and complex communication needs. This review synthesized information across 18 studies published in the past three decades (1990-2023) with the primary focus on the…

As 30% of individuals with autism spectrum disorder (ASD) demonstrate difficulties with vocal output, augmentative and alternative communication (AAC) intervention can provide a means for those persons to have the ability to communicate with others. To determine the most effective mode of AAC for individuals with ASD, practitioners must have…

This meta-analysis reviews the literature on communication modes, communicative functions, and AAC type examined during interventions with school-age participants with ASD and/or ID who experience CCN. Considering potential differences related to outcomes taught could help identify the most effective means of individualizing AAC interventions. We…

For children with autism or intellectual and developmental disabilities who also have complex communication needs, communication is a necessary skill set to increase independence and quality of life. Understanding the how, where, and communication style being taught is important for identifying deficits in the field as well as which interventions…

Purpose: Today, an ever-increasing number of technological advancements are becoming mainstream. As the availability of technological innovations increases, so do opportunities for evaluating any benefits of those innovations in augmentative and alternative communication (AAC) research for individuals with developmental disabilities. One…

Background: There are many children with neurodisability who are unable to rely on speech to communicate and so use a range of augmentative and alternative communication (AAC) methods and strategies to get their message across. Current instruments designed to measure the outcomes of speech and language therapy interventions lack specific attention…

For individuals with autism spectrum disorder (ASD) who have limited to no vocal speech abilities, mobile augmentative and alternative communication (AAC) technology provides opportunities for communication with those around them. Interventionists can incorporate evidence-based practices into AAC instruction to heighten the efficacy of its…

This review investigated virtual reality and augmented reality (VR/AR) communication interventions for children, adolescents, and adults with communication disability and neurodevelopmental disorders, as well the feasibility of these technologies. A search of five scientific databases yielded 5385 potentially relevant records of which 69 met…

Background & Aims: Speech-language pathology services are frequently accessed by families of children who have suspected or diagnosed autism. This is expected given that social communication differences are a core feature of autism. This review looked broadly at the state of research in the field of speech-language pathology and preschool…

Enabling functional communication is critical for accessibility in school and society for all pupils. This systematic review analyzed the results of educational studies on developing communication skills for learners ([less than or equal to]21 years) with autism spectrum disorder and comorbid intellectual disability. Systematic database searches…

This meta-analysis aimed to evaluate single-case studies that used high-tech speech-generating devices (SGDs) for children with autism spectrum disorders (ASD) ages 0-8. The focus of this review was to measure the effect size of high-tech SGD intervention on verbal behavior. The review included 20 studies with 54 participants with ASD. The results…
