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…

This study examined the effects of an intervention package using high-tech augmentative and alternative communication (AAC) with Naturalistic Instruction (NI), time delay, and prompting during social routines for preschoolers on the autism spectrum. The AAC was a communication application on a tablet programmed with color photo representations of…

The Picture Exchange Communication System (PECS) is an Augmentative and Alternative Communication (AAC) system which is widely used to support children with developmental disabilities. In the present study, we surveyed individuals responsible for implementing PECS in special educational settings in the United Kingdom (N=283). We explored knowledge…

Background/purpose: This study investigates the efficacy of iPad-based interventions in improving communication skills among students with autism, focusing on two participants with minimal functional speech. Materials/methods: A multiple baseline design was employed, consisting of two phases--a baseline phase (A), where the participants had access…

Purpose: The purpose of this study was to examine the effectiveness of an augmentative and alternative communication (AAC) intervention package consisting of systematic instruction and aided AAC modeling with speech-output technology on the acquisition, maintenance, and generalization of socio-communicative behaviors in four minimally speaking,…

This study examined an intervention package incorporating an iPad-based augmentative and alternative communication (AAC) application, Proloquo2Go, to improve wh-question-answering skills in a 15-year-old adolescent with autism. A single-case, multiple baseline design across three types of wh-questions ("what," "where," and…

Children who lack functional spoken language are candidates for augmentative and alternative communication (AAC). Aided AAC and naturalistic interventions offer the potential to extend the communication functions demonstrated by children with autism spectrum disorder (ASD) who are nonspeaking. Related intervention research, however, has been…

This study investigated whether a systematic instruction package was effective in child acquisition of question answering using an iPad-based speech generating device (SGD). The study was conducted with two children with autism using a multiple probe across behaviors design. Results demonstrated that the systematic instruction package consisting…

Family-centered capacity-building practices have been shown to benefit children and families. However, limited research explores these practices for children who use augmentative and alternative communication. This study explored an intervention to teach family members to implement an Aided Language Modeling (ALM) strategy across natural…

Individuals who use augmentative and alternative communication (AAC) are often excluded from learning literacy skills that use phonological approaches due to challenges with verbal production of speech sounds. This study was conducted to evaluate the effectiveness of systematic literacy instruction with materials modified to teach letter-sound…

Vestibular input (VI) activities are linked with skill learning, engagement, and communication. This study investigated the influence of VI activities on the responses of non-verbal children with autism spectrum disorders (CWASD) when prompted to request a reinforcer using picture exchange communication. A single subject alternating treatment…

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…

Approximately 30% of individuals with autism have complex communication needs (CCN). These individuals are unable to use vocal speech as their primary form of language and typically require support across several areas of communication such as comprehension, pragmatics, phonology, semantics, and syntax (Ganz et al., 2022; Reichle, 2019).…

The Picture Exchange Communication System (PECS) is a popular augmentative and alternative communication intervention for individuals with developmental disabilities that includes six, sequential phases of instruction. We systematically reviewed published and unpublished single-case PECS studies for details about the percentage of participants…

For children with autism or other complex communication needs (CCN), access to augmentative and alternative communication (AAC) systems can increase opportunities to effectively participate in many aspects of daily life. The use of AAC can enhance communication, language, and learning for children with CCN (Hidecker, 2020), and allows for…
