Makaton
Makaton (trademark) is a system of communication that uses a vocabulary of "key word" manual signs and gestures to support speech, as well as graphic symbols to support the written word. It is used by and with people who have communication, language or learning difficulties. This includes people with articulation problems (for example, people with cerebral palsy), people with cognitive impairments which might be associated with conditions such as autism or Down syndrome, and their families, colleagues and carers. It can be used to help the development of speech and language in children, or by adults as a means of functional communication for every day use.
Communication using Makaton involves speaking (where possible) while concurrently signing key words. The sign vocabulary is taken from the local deaf sign language (with some additional 'natural gestures'), beginning with a 'core' list of important words. However, the grammar generally follows the spoken language rather than the sign language. Makaton does make limited use of the spatial grammatical features of directionality and placement of signs. As Makaton is used in over 40 countries world wide, Makaton Keyword Signing varies from country to country and can even vary from state to state within each country.
Makaton was developed in the early 1970s in the UK for communication with residents of a large hospital who were both deaf and intellectually disabled. The name is a blend of the names of the three people who devised it: Margaret Walker, Kathy Johnston and Tony Cornforth.
Makaton is run by the MVDP (Makaton Vocabulary Development Project) which controls the copyright to Makaton and depends on the associated income for its funding. This restricts the use of Makaton pictograms to licensed educational programs and home use.
