Literacy skills can assist in the navigation and enjoyment of adult life. For individuals who have reached adulthood without strong literacy skills, opportunities for continued literacy learning are few. Redesigning AAC technologies to support literacy skill development could extend literacy learning opportunities for adults with developmental…

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…

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,…

In South Africa, many children with extensive support needs--including children who require AAC--are accommodated in care centers rather than the public schooling system. Caregivers employed at these centers need training in order to support children's communication using augmentative and alternative methods. A total of 29 center-based caregivers…

Participation is a fundamental human right, and being able to communicate is an essential component of participation in various life situations, such as at school, with peers, and in the community. Augmentative and alternative communication (AAC) interventions aim to facilitate communication and social interaction, independence, and participation…

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…

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…

The Picture Exchange Communication System (PECS) has been widely used to teach functional requesting and commenting skills to children with autism spectrum disorder. Some researchers also modified the PECS to explore its effect on children with other disabilities. The main purpose of this study was to add tangible symbols to PECS (PECS-TS) in…

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…

Communication partners are instrumental in the successful use and implementation of augmentative and alternative communication systems (AAC), especially in schools, but stakeholder views from low- and middle-income countries (LMICs) are not well represented in the literature. Focus group interviews with seven professionals and three caregivers…

In-service general education teachers receive limited pre-service training in Augmentative and Alternative Communication (AAC) systems and strategies. Therefore, pre-service training should expose general education teacher candidates to the field of AAC and its benefits. This study investigated the efficacy of an online professional development…
