Alternative and Augmentative Communication for students with Developmental Disabilities: A Review of the Literature

By Samantha M. Groover

This issue of NASET’s Autism Spectrum Disorder series was written by Samantha Groover. Communication is composed of verbal and nonverbal cues. Students with disabilities might be able to have nonverbal communication skills. Around 35% to 40% of all individuals with Autism, do not acquire or develop spoken language. (Hill, Flores, & Kearley, 2014). Augmentative and alternative communication (AAC) devices allow for individuals with no verbal communication to verbal communicate their wants, needs, and emotions. AAC devices also allow for students to engage in conversations, complete assignments, and interact with others. Professionals such as speech and language pathologists use AAC devices or systems to aid individuals with disabilities to understand the complex world that they live in. They also use AAC devices to allow the individual to express needs, make comments, and interact with other around them (Reis, Pereira, & Almeida, 2018).
