Literacy Interventions for Students with Physical and Developmental Disabilities Who Use Aided AAC Devices: A Systematic Review

Communicative Competence for Individuals who require Augmentative and Alternative Communication: A New Definition for a New Era of Communication?

“…This research has established empirical evidence of the positive impact of AAC (Beukelman et al, 2007;Bopp, Brown, & Mirenda, 2004;Branson & Demchak, 2009;Fried-Oken et al, 2012;Ganz et al, 2011;Machalicek et al, 2010;Roche et al, 2014;Schlosser, Sigafoos, & Koul, 2009;Walker & Snell, 2013;Wendt, 2009) and has demonstrated that these gains come at no risk to speech development or recovery (e.g., Millar, Light, & Schlosser, 2006;Romski et al, 2010). As a fi eld, we should take pride in this increased research base that has resulted in advances in evidence-based AAC services.…”

Supporting the Communication, Language, and Literacy Development of Children with Complex Communication Needs: State of the Science and Future Research Priorities

“…There is a substantial body of research that demonstrates convincingly that children with CCN derive substantial benefits from AAC (e.g., see the meta-analyses by Branson & Demchak, 2009;Ganz et al, 2011;Machalicek et al, 2010;Schlosser, Sigafoos, & Koul, 2009;Wendt, 2009). Specifically, research demonstrates that appropriate AAC intervention results in positive gains in skills such as turn taking, requesting, commenting, receptive and expressive vocabulary, mean length of message, morphology, phonological awareness, and reading and writing skills.…”

The Changing Face of Augmentative and Alternative Communication: Past, Present, and Future Challenges

“…Over the past 30-40 years, there have been substantial changes to these practices. There is now a growing body of empirical evidence documenting the positive outcomes of AAC intervention (e.g., Beukelman, Fager, Ball, & Dietz, 2007;Bopp, Brown, & Mirenda, 2004;Branson & Demchak, 2009;Fried-Oken, Beukelman, & Hux, 2012;ganz, et al, 2011;Machalicek et al, 2010;Schlosser, Sigafoos, & Koul, 2009;Wendt, 2009). Moreover, there is evidence that AAC interventions pose no risk to speech development or recovery (e.g., Beukelman & Mirenda, 2013;Millar, Light, & Schlosser, 2006;Schlosser & Wendt, 2008).…”

“…There is a growing body of research that demonstrates convincingly that individuals with complex communication needs can derive substantial benefits from AAC (e.g., Beukelman et al, 2007;Branson & Demchak, 2009;Fried-Oken, Beukelman et al, 2012;ganz et al, 2011;Machalicek et al, 2010;Schlosser et al, 2009;Wendt, 2009), with no risk to speech development or recovery (e.g., Beukelman & Mirenda, 2013;Millar et al, 2006;Schlosser & Wendt, 2008). The accumulated research evidence extends across the life span of individuals with a wide range of developmental and acquired disabilities, and supports the positive impact of a wide range of AAC techniques, including unaided systems such as signs; aided systems such as nonelectronic low-tech symbols or symbol boards; and hightech speech-generating devices.…”
