Augmentative & Alternative Communication header

Autism is a complex developmental disability which often impacts the acquisition of social and communication skills to varying degrees in affected individuals. Although there is significant variability in the severity of symptoms, many individuals with autism are nonverbal or demonstrate delayed or impaired communication skills. Because communication impairment is at the core of the autism syndrome, a body of research is developing focused on the development of effective communication interventions for this population. One area that holds promise for helping people with communication impairment is the use of augmentative and alternative communication (AAC) strategies.


People with varying degrees of speech or language challenges rely on Augmentative and Alternative Communication (AAC) to supplement or replace non-functional speech. AAC includes all methods of communication that are used to express an individual’s thoughts, needs, hopes, desires, and ideas, with the exception of conventional oral speech and traditional writing. The idea behind AAC is to use the individual’s existing abilities, whatever they are, to compensate for their difficulties and to make communication as efficient, simple and effective as possible when speech alone does not work. AAC users are encouraged to use speech to the extent that they are comfortable and able, while simultaneously using various AAC aids and devices to enhance their communication.

It is important to note that there is not just one type of AAC. Rather, AAC encompasses a whole range of different activities which includes facial expression, eye pointing, gesture, signing, symbols, spelling out a message on a letter board or computer, electronic speech output aids, etc. There are two main categories of AAC systems: unaided and aided. Most people who use AAC use a combination of unaided and aided methods.

Unaided AAC includes methods of communication that do not involve a piece of additional or external equipment. Body language, gestures, pointing, eye pointing, facial expressions, and sign language are each examples of an unaided method of augmentative communication.

Aided AAC includes methods of communication which do involve additional equipment, such as a picture chart, computer or special communication aid. Aided methods of augmentative communication are categorized as either 'low-tech' or 'high-tech.' Both low- and high-tech systems can be used by people who are unable to spell or read, by people who are literate, as well as by people who through increased exposure may learn to develop literacy.

Low-tech communication systems take many forms and do not require a battery to function. Low-tech communication systems include a pen and paper to write messages, alphabet charts, charts and books with picture symbols or photos, and tangible symbols.

High-tech communication systems are devices requiring at least a battery to operate. High-tech systems range from simple high-tech (e.g. single message devices, pointer boards, toys or books which speak when touched) to very sophisticated systems (e.g. specialized computers and programs, electronic aids which speak and/or print).

There is no single AAC system which works best for everyone. Each has its own pros and cons and the most suitable system for an individual will depend on personal preference as well as on specific skills, abilities and needs. As an individual’s abilities and skills grow, the methods or types of AAC used may evolve or change to suit his/her developing needs, skills and preferences. One AAC strategy that has been particularly useful for some individuals with autism is Facilitated Communication (FC).


Facilitated communication is one of an array of augmentative and alternative methods of expression for people who cannot speak, or whose speech is highly limited (e.g. echoed, limited to one or a few word utterances), and who cannot point reliably. This method has been used as a means to communicate for individuals with severe disabilities, including persons with labels of mental retardation, autism, Down syndrome and other developmental disabilities.

The idea of facilitated communication is to make it easier for a person with a severe communication impairment to use a communication device, usually a portable aid that displays letters, words or pictures. The support varies, from assistance to isolate the index finger, support under the arm to slow down impulsive responses, pulling back on the arm after a selection, monitoring of eye hand coordination with reminders for the person to look at the target, or just a hand on the shoulder to convey confidence.

The idea behind facilitated communication is that a communication partner or trainer aids the individual to overcome neuro-motor problems that impede reliable pointing. Over time, the goal of facilitated communication is to help the person learn to communicate independently. This may require a combination of confidence building and improvement in physical skills of pointing.


A number of books and monographs describe the method and how to provide training as well as how to assess progress with the method. These include:

Biklen, D. (1993). Communication unbound. New York: Teachers College Press.

Biklen, D. & Cardinal, D. (Eds.) (1997) Contested words, contested science: Unraveling the facilitated communication controversy. New York: Teachers College Press.

Crossley, R. (1994). Facilitated communication training. New York: Teachers College Press.

Books that reveal the progress of individuals who first learned to communicate with facilitation include:

Crossley, R. (1997) Speechless. New York: Dutton.


Facilitated communication is controversial. This is because it has been shown that a facilitator’s physical touch of the typist’s hand or arm may influence a person’s pointing, and because a number of studies failed to validate authorship (Bebko, Perry, and Bryson, 1996; Bomba, O’Donnell, Markowitz, and Holmes, 1996; Cabay, 1994; Crews, Sanders, Hensley, Johnson, Bonaventura and Rhodes, 1995; Eberlin, McConnachie, Ibel, and Volpe, 1993; Klewe, 1993; Montee, Miltenbgerger, and Wittrock, 1995; Moore, Donovan, Hudson, Dykstra, and Lawrence, 1993; Regal, Rooney, and Wandas, 1994; Shane and Kearns, 1994; Smith and Belcher, 1993; Szempruch and Jacobson, 1993; and Wheeler, Jacobson, Paglieri, and Schwartz, 1993).

Other studies, using a range of test situations as well as linguistic analysis and documentation of physical, independent-of-facilitator typing have successfully demonstrated authorship (Broderick and Kasa-Hendrickson, 2001; Calculator and Singer, 1992; Cardinal, Hanson, and Wakeham, 1996; Emerson, Grayson, and Griffiths, 2001; Janzen-Wilde, Duchan and Higginbotham, 1995; Niemi and Karna-Lin, 2002; Rubin, Biklen, Kasa-Hendrickson, Kluth, Cardinal and Broderick, 2001; Sheehan and Matuozzi, 1996; Weiss, Wagner and Bauman, 1996; and Zanobini and Scopesi, 2001). The studies by Cardinal and his colleagues (1996), Sheehan and Matuozzi (1996), and Weiss, Wagner and Bauman (1996) all involved message passing experiments, but unlike many of the assessments in which individuals failed to demonstrate authorship, these included extensive testing sessions, with the possible effect of desensitizing the subjects to test anxiety. Other studies noted above in which individuals successfully demonstrated authorship employed unobtrusive assessments such as linguistic analysis and observations of independent typing after a period of facilitated typing.

Concerning the latter, Beukelman and Mirenda (1998) state, “in regard to a small group of people around the world who began communicating through FC (facilitated communication) and are now able to type either independently or with minimal, hand-on-shoulder support... there can be no doubt that, for them, (facilitated communication) ‘worked in that it opened the door to communication for the first time.... For them, the controversy has ended' (p.327). In recent years, individuals who have begun to type independently have published autobiographical accounts (Blackman, 1999; Mukhopadhyay, 2000; Rubin, Biklen, Kasa-Hendrickson, Kluth, Cardinal, and Broderick, A., 2001) and one is featured in a research article on learning to speak after first learning to type (Broderick and Kasa-Hendrickson, 2001).
