What are Augmentative Devices, and How Can They be Used With Children Who are Not Speaking?
Some children with fragile X syndrome, particularly boys, do not begin speaking until very late, and a few do not speak at all. This inability to speak may be based upon cognitive levels, processing problems with language,
and/or oral-motor problems. Many of these children understand more than they can say, such that the use of augmentative or alternative communication (AAC) devices may be helpful in allowing their thoughts and desires to be
known.
Augmentative and alternative communication (AAC) encompasses all kinds of communication, from gestures and sign language, to
picture cards, communication boards, and computerized interactive devices. AAC allows for the development of speech and language in those who are non-verbal, and it can serve as a bridge to spoken language.
AAC can accompany oral language, so that a communication partner offers the child with fragile X both the auditory input (words
and sentences) and a visual cue (a picture, sign, logo, or gesture). This can strengthen the child's understanding of language.
In addition, AAC offers the child a way to express himself. By pointing or gesturing, a non-verbal child can make his wants or needs known. This
ability may also help with behavioral difficulties, such as screaming or hitting, that have occurred because the child cannot be understood.
For non-verbal boys with fragile X, words and visual symbols should be chosen to best help their communication needs. Real objects, photographs,
and clear, realistic drawings are the most concrete visually. Some more symbolic drawings may need to be used on a communication board (e.g. symbol for "want"), and gradually children may be able to comprehend more
abstract symbols. Some may even be able to read words.
Parents may be concerned that the use of AAC will prevent their child from talking. On the contrary, AAC has helped many children to grow in their
language learning, integrating their use of the AAC device with vocalizations and gestures.
