The Nature of and Factors Related to Reading Difficulties Among Adolescents in a Transparent Orthography

We examined the nature of and factors related to adolescents' reading difficulties in a highly transparent orthography. We compared word, pseudoword, and text reading speed and accuracy, rapid naming (RAN) and phonological processing between poor readers (n=80) and normally developing readers (n=189). Reading problems were manifested in reading speed and in timed pseudoword reading accuracy. RAN predicted speed, and phonological processing predicted accuracy of reading in both groups. Among poor readers, RAN also explained reading accuracy. For the normally developing sample, phonological processing also predicted reading speed.
