Reading-related abilities underlying phonological awareness: a cross-sectional study in children with and without dyslexia

Purpose:The present cross-sectional study examined the individual role of rapid automatized naming (RAN), verbal short-term memory (VSTM), and phonological verbal fluency (PVF) along with word reading performance in predicting phonological awareness (PA). Materials and methods:A total of 225 Arabic speaking children from grades 2, 3, 4 and 5 took part in this study, divided into two groups of readers: typical developing readers and dyslexic readers. The participants were tested on word and pseudoword reading, phonological awareness, rapid naming, verbal short-term memory and phonological verbal fluency. Results:There are different predictive patterns between the two groups. Whereas Raven and Grade contributed directly in predicting PA in typical readers, VSTM and PVF directly predicted PA in children with dyslexia. However, word reading played a dual role in the both groups as direct predictors of PA, mediating the predictive relationships between PA and the other variables. Conclusion:The results suggest the potential existence of an underlying phonological representation processing ability shared between PA, phonological access (RAN and PVF), VSTM, and word reading ability.
