“…the attainment of communicative competence is predicated, at least in part, upon linguistic skills, including receptive and expressive skills in the spoken and written language(s) of the individual’s home and broader social community, as well as skills in the language code of the AAC systems used to communicate in these environments.”
Light & McNaughton (2014)
What are we talking about?
“AAC therapy is language therapy.“
Have you seen or heard this before? The linguistic competence skill area is what they are talking about. The actual language skills a person needs to be able to communicate anything they want.
Language skills are not the only skills needed to be a proficient communicator (as illustrated in the infographic above). But, a huge part of achieving communicative competence is learning language skills. Language is often what we focus on first when starting AAC with someone. We want them to realize the power of the tool we are trying to help them learn to use. And we want to hear all their thoughts and feelings and ideas and stories and everything else they want to tell us!
Language skills include:
- receptive language (understanding)
- “spoken” and written
- expressive language (ability to communicate a message to someone else)
- “spoken” and written
For people who use AAC, this is double (or more) the work. They have to learn the language(s) used in their home and community, as well as the language code(s) of their AAC system.
The Skills
Skills within the linguistic competence area include knowledge, use, and judgement of:
- vocabulary (words)
- grammar/syntax (rules of how to put words together)
- morphology (word structure and meaning of word parts, such as -s added to the end of a word to mean more than one)
- symbols (including those needed for written language, signs, pictures, and other symbols used in their AAC language)
The Goal
The goal is for the person to be able to understand and use language the same as their same-age peers. This includes having literacy abilities equal to their same-age peers. We can use what we know about language development as a guide to help us plan our interventions.
