Using Augmentative and Alternative Communication (AAC) supports

AAC describes any form of language other than speech that assists a child in social-communicative interactions. There is a large range of AAC devices available for children who have no speech, and these children themselves are very diverse. Therefore, it is essential that a team of appropriate individuals evaluate different AAC options with the parents of a child with ASD, before a decision about their use is made. Criteria that need to be discussed before an AAC device is implemented include, cognitive and motor abilities, learning style, communication needs and literacy ability.

The use of AAC devices for children with ASD can be particularly helpful.   Those children with ASD who have no spoken language often resort to challenging behaviours to meet their needs and feelings. The use of an AAC device can give them a primary means of social communicative interactions with others. If it is decided that an AAC device is appropriate for the child it is the responsibility of those around them to model the system.

Different types of AAC devices that are suitable for the child with ASD include:

  • Picture Exchange Communication System (PECS, Frost and Bondy, 1994)
  • Sign Language
  • Interactive Communication Boards
  • Communication Cue Cards
  • Conversation Books
  • Voice Output Communication Aids.

Sign language

There are several difference sign language systems, for example, American Sign Language (ASL), British Sign Language (BSL), MakatonTM , Paget Gorman Signed SpeechTM  and Signed Exact English. When using sign language with a child with an ASD, it can be beneficial to use a total communication approach. Total Communication is the use of combined speech and sign so that the same language structure is modelled for the child in two modalities. The use of total communication helps to highlight key word meanings and help language comprehension.

Interactive communication boards

Interactive Communication Boards contain visual symbols organised by topic. They can be created in different sizes and formats depending on the activity and environment that they are needed for. They can be both portable and stationary - one board is designed to stay in one location. The selection and organisation of the symbols that are used need to be motivating and chosen to enhance functional communication for the child.

Cue cards

Cue cards are primarily used with verbal children. They are used to remind the child what to say and to provide them with an alternative means to communication. They can contain one or more messages in pictorial or written form and can replace verbal prompts. They are therefore, particularly useful for children who are reliant on verbal prompts. Cue cards can work well in situations where the child with an ASD needs to express a message in a stressful situation.

Conversation books

A conversation book can be pictorial or consist of a written summary of conversation topics used for increasing conversational abilities. The conversational topics are organised in a small book, wallet or something similar and are used as a focus of conversation with an adult. It is important that the book is age appropriate and the topics chosen, meaningful to the child. This can often be achieved best using photographs - especially for the younger child. Conversation books work by organising the conversation for the child. They provide a concrete, visual means to share and maintain topics.

Voice output communication aids

Speech output devices give non-verbal children a 'voice'. A team of relevant professionals should determine the most appropriate technology option. Once this has been established the team then need to decide on an appropriate vocabulary selection, the layout of the device, the size of the symbols and the principal situations to encourage the child to use the device. There are a wide range of devices available including simpler ones for people who do not understand visual symbols. In order to use these devices, the child will need an understanding of cause and effect. One type of such a device is the BIGmackTM  (contact Ability Net or the Ace Centre for further information).

The combined use of AAC, social supports, organisational supports and visually cued instruction can enhance the social communicative interactions in children with autism.
