AAC Myths and Facts


As you learned in last month’s blog post, use of AAC can help children to communicate their wants, needs, feelings, and ideas. But how do we know when AAC is appropriate to use? Are there cases in which spoken language alone should be modeled? In this week’s post, we are exploring common misconceptions about AAC and providing you with research evidence to help you better understand just how useful AAC can be!


MYTH #1: Using AAC will hinder spoken language development and should not be used until the use of natural speech has been ruled out.


FACT: The introduction of AAC does not hinder the development of natural speech. In fact, AAC has actually been found to increase natural speech when therapy utilizes a multimodal approach of simultaneously targeting AAC and spoken communication (Millar, Light, and Schlosser, 2006; Sedey, Rosin, & Miller, 1991). A 2014 study with minimally-verbal individuals with ASD found that an intervention that involved a Speech Generating Device (SGD) increased the use of novel utterances compared with the same intervention which did not use an SGD. (Kasari et al). Additionally, for children who struggle with challenging behaviors, AAC can help them to more effectively communicate their wants and needs, reducing the frustration that may result from communication breakdowns (Carr & Durrand, 1985; Drager, Light, & McNaughton, 2010; Mirenda, 1997; Robinson & Owens, 1995).


MYTH #2 Young children are not able to use and understand AAC.


FACT: Early introduction of AAC can aid in the development of natural speech and language (Lüke, 2014; Romski et al., 2010; Wright, Kaiser, Reikowsky, & Roberts, 2013) and can increase expressive and receptive vocabulary for children younger than 3 (Romski, Sevcik, Barton-Hulsey, & Whitmore, 2015; Brady, 2000; Drager et al., 2006).


MYTH #3: There are cognitive prerequisite skills for using AAC, and it is not appropriate for children with cognitive disabilities.


FACT: Development of language skills through AAC can actually lead to functional cognitive improvement (Goosens’, 1989). AAC intervention for children with complex communication needs helps children develop communication skills, promotes cognitive development, provides the foundation for literacy development, and improves social communication (Drager et al., 2010).
