Considerations in the Planning of Communication Intervention: Selecting a Lexicon

Abstract

Principles, processes, and information that can be used in selecting an initial lexicon are discussed. Two strategies for lexicon selection, one based upon functional-remedial logic and the other upon developmental considerations, are presented together with guidelines for selecting lexical items derived from each. Data from validation studies undertaken to determine the usefulness of a sample lexicon for elementary- and adolescent/adult-aged severely handicapped individuals are examined. An example of a lexicon for adolescent/adult-aged individuals resulting from the validation studies is also presented. Finally, the compatability of the two lexicon selection strategies is discussed.
