The selection of the initial lexicon is one of the most important decisions made in the implementation of augmentative communication systems with preliterate, nonspeaking preschool children. If a communication aid is to be adopted by a child, the words available on the device must be interesting to the child and encourage communication. The vocabulary must allow for cognitive growth and foster language development. Ideally, a lexicon would be customized for each nonspeaking child's particular interests, vocabulary needs and developmental level. The reality is that vocabulary selection is a difficult and time consuming process. Parents and clinicians do not always have the time or expertise to develop an individualized lexicon and must depend on a prepared list. These lists are not always appropriate for preschool children. A carefully developed core vocabulary could serve as a framework for the initial lexicon and would ensure that the words available to the children promoted communication and language growth. This would allow caregivers to concentrate on the smaller individualized portion of the lexicon.
