An exploratory study of phonological awareness and working memory differences and literacy performance of people that use AAC.
Twelve cerebral palsied adolescents and young adults with complex communicative needs who used augmentative and alternative communication were studied. They were classified according to their working memory capacity (high vs. low) into two groups of 6 participants. They were also divided into two groups of 6 participants according to their high vs. low phonological skills. These groups were compared on their performance in reading tests -orthographic knowledge, a word test and a pseudoword reading test- and in the spelling of words, pseudowords and pictures' names. Statistical differences were found between high vs. low phonological skills groups, and between high and low working memory groups. High working memory capacity group scored significantly higher than low working memory group in the orthographic and word reading tests. The high phonological skills group outperformed the low phonological skills group in the word reading test and in the spelling of pseudowords and pictures' names. From a descriptive point of view, phonological skills and working memory, factors known to be highly predictive of literacy skills in people without disabilities, also hold as factors for the participants that used AAC in our study. Implications of the results are discussed.
