Predicting Individual Differences in Reading and Spelling Skill With Artificial Script–Based Letter–Speech Sound Training

Abstract

In this study, we examined the learning of letter–speech sound correspondences within an artificial script and performed an experimental analysis of letter–speech sound learning among dyslexic and normal readers vis-à-vis phonological awareness, rapid automatized naming, reading, and spelling. Participants were provided with 20 min of training aimed at learning eight new basic letter–speech sound correspondences, followed by a short assessment of mastery of the correspondences and word-reading ability in this unfamiliar script. Our results demonstrated that brief training is moderately successful in differentiating dyslexic readers from normal readers in their ability to learn letter–speech sound correspondences. The normal readers outperformed the dyslexic readers for accuracy and speed on a letter–speech sound matching task, as well as on a word-reading task containing familiar words written in the artificial orthography. Importantly, the new artificial script-related measures were related to phonological awareness and rapid automatized naming and made a unique contribution in predicting individual differences in reading and spelling ability. Our results are consistent with the view that a fundamental letter–speech sound learning deficit is a key factor in dyslexia.
