This book explored the cognitive correlates that best predicted
irregular word, non-word, and word reading, and reading performance of
typical and poor readers. The findings indicated that processing speed
had the strongest correlation with irregular word reading, whereas rapid
automatized naming (RAN) had the strongest correlations with word
reading and non-word reading. As with previous research RAN letters was
the best predictor of reading skills. The best model for predicting
reading was based on a combined measure of phonological awareness (PA)
and RAN letters. An interesting finding was that the correlation between
irregular and non-word reading was significant for students with typical
reading, but insignificant for the poor readers. These findings provide
support for both the dual-route and double-deficit theory of dyslexia
that ascribes independent contributions of PA and RAN to the development
of reading skills. This book presents information that will help school
psychologists, neuropsycholoists, educational diagnostician, special
education teachers, as well as general education teachers, to recognize,
assess, and provide effective treatment programs for dyslexia.
