Language Representation Method Issues in AAC: All Are Not Equal.
This paper explores three different language representation methods used to access vocabulary in augmentative alternative communication (AAC) and identifies which are most effective for core and extended vocabulary. The benefits and drawbacks of using spelling, single meaning pictures, and semantic compaction (Minspeak) are described. The paper finds that for access to core vocabulary, research suggests a ranking of semantic compaction, spelling, and single meaning pictures in order of effectiveness. For access to extended vocabulary, the order would be spelling, single meaning pictures, and semantic compaction. The paper stresses, however, that total communication requires access to both core and extended vocabulary and that monitoring the language activity of highly effective users of AAC has indicated that they use a combination of semantic compaction and spelling, sometimes with word prediction. The paper concludes that for most people who rely on AAC and have a language age of two years or more, the use of multiple language representation methods results in the most effective communication. Those methods include semantic compaction for core vocabulary access and spelling and/or single meaning pictures for extended vocabulary access. (Contains 12 references.) (CR)
