AAC
Augmentative and
Alternative Communication strategies may start as early
as 3 months old. A caregiver of an infant with special
needs may need to learn strategies to build interaction
and attachment skills. A toddler with limited vocabulary
may need to use sign language or pictures to help
facilitate words. A school-age student with Autism may
need a communication aid to assist with language
comprehension and expression. Augmentative and
alternative communication is a way to “add to” or
augment a child’s natural communication behaviors. These
strategies help reduce frustration and build language
skills.
“It is the position of the
American Speech-Language-Hearing Association (ASHA) that
communication is the essence of human life and that all
people have the right to communicate to the fullest
extent possible. No individuals should be denied this
right, irrespective of the type and/or severity of
communication, linguistic, social, cognitive, motor,
sensory, perceptual, and/or other disability(ies) they
may present.
AAC is best thought of as a
system, as opposed to a single entity (Calculator,
2000). An AAC program
neither begins nor terminates with the prescription of a
communication aid. Instead it involves an ongoing
program of decision-making that considers individuals,
their methods of communicating, and the effectiveness of
that communication with a variety of listeners, as well
as environmental variables that foster or impede
communication. The specific unaided and aided methods of
communication that are associated with this area of
practice constitute one small part of the AAC domain,
which is composed of four primary components: symbols,
aids, strategies, and techniques.
Symbols.
A variety of symbol types are available: graphic,
auditory, gestural, and textured or tactile.
Aids.
The term “aid” refers to a device, whether electronic or
nonelectronic, that is used to transmit or receive
messages.
Strategies.
This term refers to the ways symbols can be conveyed
most effectively and efficiently.
Techniques.
This fourth component of an AAC system consists of the
various ways in which messages can be transmitted.”
