Acquisition of language for individuals who utilize augmentative and alternative communication (AAC) can look different from children who speak, as children with communication disorders have limited modeling exposure of their expressive language systems. Oftentimes, children with severe communication disorders experience a lack of congruence between their levels of input when compared to their expressive output of language. The purpose of this investigation was to determine the effect of aided language stimulation of core vocabulary on individuals with severe to profound communication disorders who utilize alternative access speech-generating devices (SGDs).
