What is AAC?

AAC DeviceAAC, or Augmentative and Alternative Communication, is a phrase describing a collection of methods of communicating information for people who have difficulty communicating via speaking or writing. AAC includes sign language, gestures, visual regard, pointing, writing, typing, spelling on alphabet boards, selecting words or pictures from a book or tablet, pushing switches to activate pre-recorded messages, sophisticated computerized voice output systems, among others.

"Unaided" AAC refers to any form of communication other than speech that involves the individual's own body. This includes sign language, facial expressions, eye pointing, vocalizations, etc.

"Aided" AAC refers to any form of communication that involves using a piece of equipment whether it be paper and pencil, pictures, symbols, books, computers, etc. Low tech aided AAC systems are those that do not require an additional power source such as batteries or electricity to operate. This would systems such as picture books, object boards and alphabet boards. In contrast, High tech AAC systems are those that do require a power source such as computers and other electronic type devices that speak when activated.

AAC Myths

AAC DeviceMyth #1: "Using AAC will interfere with your child's ability to learn to talk."

The Truth: The use of AAC, whether it be low tech such as sign language and picture books or high tech such as switch devices and computerized voice output systems actually ENHANCE speech and language learning. Berry (1997) states that, "Parents should be told that extensive research has demonstrated that the use of non-speech communication systems does not reduce the motivation for speech communication, and in fact, seems to facilitate speech." The consistent speech model of voice output devices is theorized to be a positive influence on speech development, as is the pairing of visual symbols with the auditory words.

Myth #2 "If my child gets an AAC system, they will get lazy and give up on using speech."

The Truth: Taking the pressure off of using verbal speech as the only means of communication coupled with the benefits of continued language learning often helps children to develop speech. Children will automatically resort to the most efficient means of communication, which is speech and/or vocalization over some form of AAC. In a review of the literature, Light & Schlosser (2006) discovered that after the introduction of AAC, 89% of those studied Increased their speech production, 11% demonstrated no change in the speech production and none of those studies decreased their speech production.

MYTH: #3 Children and adults with significant intellectual challenges obtain minimal benefit from AAC

The Truth: In fact, the opposite is true. The tangible nature of many AAC systems such as pictures and object boards can make the symbolic nature of language more salient. Additionally, there is an increase in learning to be a communicator because the AAC system actually encourages others to communicate more to the user than if there was no system in place.

Myth #4 My Child is talking so there is no need for AAC

The Truth: That might be true…or not. Or, perhaps that is sometimes true. Often familiar people are able to understand and communicate well with their children but other folks can not. In these cases, AAC is necessary for those times when the individual is not understood; maybe at school, or church, or at boy scouts, or perhaps during periods of fatigue or in noisy environments. Everyone deserves the right to be able to fully express themselves despite the environmental conditions.

Myth #5 There is such a large cognitive delay

The Truth:

Myth #6 My child is too young to need or benefit from AAC

The Truth:The reality is, it is important to introduce AAC as early as possible. that the younger the child is, the more quickly AAC will benefit them. Research has demonstrated that when we empower children through some form of communication; it is easier to work on verbal speech. As children learn language and communication skills via their AAC, they also develop things to talk about and want to express their opinions. Being able to tell others what they want or being able to tell others what to do is motivating for children and encourages them to also use their verbal speaking skills no matter how limited they may be at the present.

Who Benefits?

AAC DeviceAnyone who is experiencing short term or long term difficulties communicating through traditional speech will benefit from some form of AAC, whether it be "high tech" or "low tech". Some examples of people who benefit from AAC include individuals with cerebral palsy, Down Syndrome, autism, developmental delays, apraxia. Other people who might benefit are those whose communication skills have been reduced due brain injury, stroke, accidents or illnesses such as meningitis, ALS and Parkinson's Disease.

What To Expect From an Alternative & Augmentative Communication (AAC) Evaluation

AAC DeviceThe goal of the evaluation is to decide on a communication mode or system for your child that will be fast, easy to operate, able to meet his/her communication needs, and still has the capability of expanding as your child's language skills become more sophisticated. The first order of business is to identify the current methods of communication that ARE working. For example, your child may point toward objects of desire and vocalize to protest while another nods her head to indicate, "Yes", says "Ma" to call her mother and has a working approximation for the sign, "more". Another child may not use verbal words but successfully communicates basic wants and needs by pointing, pulling, looking and tears of frustration, while a fourth may communicate verbally with close family and friends, but need family to translate his words to unfamiliar listeners. These methods of communication are probably more or less reliable and functional in different settings. Our mission is to determine a system that will be consistently reliable in all settings. To that end, we first determine how and where your child is successfully communicating. Then we explore what methods will improve upon those successes across an expanded range of people and places.

To narrow our range of AAC choices, we will we will assess your child's language, cognitive, social and motor skills by reviewing results of previous evaluations, interviewing you, conducting formal testing and/or observing your child interact with the world. Next, we will partner with you to develop a set of realistic goals targeting expanded communication in identified educational, vocational, social and recreational settings. Once these pieces are in place, we will begin a trial of different AAC systems.

To systematically guide the selection of which AAC systems to try, every AAC evaluation conducted at CLASS, Inc. identifies the following:1

  1. A means of representing thoughts/ideas
    • This could consist of any combination of pictures, drawings, photos, printed words, letters, symbols, objects, etc.
  2. A method of accessing the AAC system itself
    • For example, by touching buttons or keys, looking at pictures, pulling a message card off of a board, or by using a switch/scanning system or an optical reader to access the messages.
  3. A system or tool to transmit the actual message
    • Some children use communication notebooks of pictures, others use sign language or gestures, typing, computerized speech generating devices, eye gaze boards or miniature objects attached to switches.

AAC Systems

AAC DeviceAugmentative and Alternative Communication (AAC) systems are any system, tool or device that an individual uses to supplement his or her existing communication. AAC systems are typically divided into two categories: unaided and aided. Unaided systems are those that the individual can access directly without any additional piece of equipment. Unaided systems include gestures, eye gaze, sign language, pointing, pantomiming, and facial expressions. Aided systems are those that the individual accesses through ancillary object, device or technology and can be either "Low tech" or "high tech". "Low tech" aided systems do not involve technology such as communication books, object boards, speech generating devices and computers. "High tech" aided systems do involve technology and are generally voice output communication aids (VOCAs) that can be activated by either touching buttons or via scanning with switches.

Individual Therapy

Learning to use an AAC DeviceAt CLASS, Inc. individual therapy services for AAC users is multimodal. We focus on efficient and effective communication by incorporating speech, vocalizations, gestures, signs, and aided communication strategies into every session. By increasing communication speed and broadening the scope of communicative topics the user can participate it we open up doors of opportunity. Therapy sessions are individualized to target the unique goals of each client; some examples of individual goals are to: inform caregivers of pain or discomfort, participate in circle time, ask for assistance, engage in academic discourse, partake in leisure activities, chat with friends/family and order food in restaurants. Individual therapy AAC therapy sessions are often the best venue for learning new skills that can then be practiced in our dyads or social skills groups and have been shown to increase our clients' participation in meaningful activities at home, school and out in the community.

Peer Dyad Therapy

Boys using AAC DevicePeer Dyads are semi-structured therapy sessions where two AAC users work together toward common goals while supporting each other's individual goals. By including communication partners in the therapeutic process, the AAC user learns to attend to both his communication as well as that of his partner, thus strengthening social communication skills. This is particularly important for AAC users because their communication is inherently slower than that of non-users so they need to learn how to be as fast as possible and as engaging as possible in order to maintain the interest of their partner.

Teaching Techniques

SocializingThere is no single technique or composite of techniques that will work with each individual. The only common denominator is that the instructional sessions must be fun and meaningful in order for them to be integrated, maintained and applied in functional social communicative contexts. Consistency is critical for rapid learning. Goals and strategies should be consistent across environments such home, school and community (e.g. work, church, recreational settings).

AAC Social Groups

SocializingCommunication encompasses much more than just telling others what you want. It involves social closeness, relaying information, asking questions, expressing empathy, engaging in humorous exchanges, revealing emotions, politely disagreeing, displaying social graces and more. Many AAC users have had little experience in social settings. Without ongoing, consistent social experiences, AAC users become socially delayed and/or lose interest in being social.

AAC social skills groups target the three elements of social success as defined by Kristen Stanberry:

  • Social Intake - noticing and understanding other people's speech, vocal inflection, body language, eye contact, and even cultural behaviors.
  • Internal Process - interpreting what others communicate to you as well as recognizing and managing your own emotions and reactions.
  • Social Output - how a person communicates with and reacts to others, through speech, gestures, and body language.

CLASS, Inc. AAC social groups teach the user all of these skills while also teaching new leisure activities such as bowling, basketball, crafts, games, gardening and community service.

By introducing AAC into our lives, my husband and I learned many things we didn't know about our son - for example, he could finally tell us what he really wanted for dinner, that he wanted to get out and walk around while we were parked on the ferry and that he wanted a dog. - Raven McCrackyn
