Estrategia de matrices y jerarquía creciente de incitaciones para expresar relaciones semánticas combinando símbolos en la discapacidad intelectual

Abstract

IntroductionThere are few studies on the expression of semantic relationships using graphic symbol combinations by the application of the matrix strategy and a hierarchy of increasing prompts to intellectually disabled adults. The aim of this study is to investigate the effect of the matrix strategy and an increasing prompt hierarchy in the context of shared story reading on the production of graphic symbol combinations in three adults with moderate to severe intellectual disability. MethodsA single subject, multiple probe design across different types of semantic relationships generated from a matrix combination was used. A hierarchy of increasing prompts for the production of symbol combinations was applied to three individuals. ResultsIt was shown that the application of the training strategies was successful in teaching the participants to produce targeted semantic relationships combining symbols, in order to extrapolate to untrained models, and for the maintenance of post-intervention skills. ConclusionsEven significant intellectually disabled adults may learn to combine symbols for the expression of semantic relationships when appropriate interventions techniques are applied.
