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 We systematically reviewed published and unpublished single-case PECS studies for details about the percentage of participants…

Purpose: Interventions that target the full breadth of communication skills for individuals who use augmentative and alternative communication (AAC) are needed in the literature. Narrative interventions for AAC would target the important communication skill of storytelling and may have broader academic and social effects. The authors review the…

Parental support is an important part of introducing an augmentative and alternative communication (AAC) system to a child. Professionals providing AAC services to children with complex communication needs should practice family-centered service provision. The aim of this study was to explore Sri Lankan parents' perspectives on AAC and their lived…

Many children with intellectual and/or developmental disabilities benefit from augmentative and alternative communication strategies (AAC) to increase their communicative competency. Furthermore, caregiver-implemented AAC interventions are an effective and efficient strategy to improve communication outcomes. We reviewed the caregiver-implemented…

Background & aims: Although the Picture Exchange Communication System (PECS) has been demonstrated to be an effective intervention to teach people diagnosed with autism spectrum disorder a functional communication system, the research indicates variability in PECS outcomes across people and studies. Therefore, the purpose of the current study…

Background: Non-standardized assessment tools are preferred when assessing communication of individuals with developmental disabilities. Currently, there are limited tools available for assessing this population. Informant report tools such as the Pragmatics Profile (PP) of Everyday Communication Skills are beneficial in gathering a representative…

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…

Parent training programs aimed at improving language outcomes for children with complex communication needs have predominantly been evaluated on child-centered outcomes and less often on the impact on social life or parental well-being. This study examined parent perceptions of social life before and after ComAlong, a group intervention providing…

Literacy plays an especially important role in aided augmentative and alternative communication (AAC) because spelling and writing support precise communication. Fortunately, the importance of literacy is reflected in federal legislation that mandates that all students, regardless of ability, receive comprehensive literacy instruction.…

Eye tracking research technologies are often used to study how individuals attend visually to different types of AAC displays (e.g. visual scene displays, grid displays). The assumption is that efficiency of visual search may relate to efficiency of motor selection necessary for communication via aided AAC; however, this assumption has not…

Establishing evidence- and research-based practices relies upon research synthesis of individual studies in reviews and meta analyses. Further summarizing scientific evidence about a specific topic by synthesizing reviews is an area of need to determine practices that have a strong evidence base and to identify areas of methodological weakness and…

Children with developmental disabilities and complex communication needs who use augmentative and alternative communication (AAC) have limited opportunities to communicate and few trained conversation partners to interact with. Research literature on interventions utilizing AAC devices and systems to increase communication skills overwhelmingly…

The general education classroom is filled with academic vocabulary, and individuals with developmental disabilities benefit from explicit vocabulary instruction (Browder et al., 2008; Marzano, 2020; Smith et al., 2013). Picture-based alternative and augmentative communication (AAC) can encourage academic skills development (Ahlgrim-Dehzel et al.,…

Individuals with developmental disabilities often do not develop vocal repertoires, thus requiring the use of augmentative devices. Teaching caregivers to conduct communication training with their children may be one way to foster communication with their device in the natural environment. This study replicates Rosales, Stone and Rehfeldt (2009),…
