This present study focuses on classifying developmental dyslexia by combining two famous models, the dual-route model and the triangle model of Chinese reading, re-examining validity of the subtypes, and observing the error types of word recognition for each subtype. Sixty-sixth graders with dyslexia in Chinese and 45 sixth graders who were matched by age and IQ with the dyslexic group were involved in the present study. Twelve (20%) sixth graders from the dyslexic group were classified as having phonological dyslexia, 11 (18.3%) were classified as surface dyslexia, 12 (20%) were classified as deep dyslexia, and five (8.3%) of them were classified as displaying more than one kind of deficit. Besides, still more than half (31; 51.7%) of the dyslexic group did not belong to any subtypes here. These subtypes had a good validity based on comparison of their phonological awareness, orthography, and semantics. Finally, for their error types of word recognition, both children with multiple-deficit dyslexia and children with non-subtype dyslexia showed a proportional pattern of six kinds of errors. Children with phonological dyslexia showed more phonetic errors and analogy errors, children with surface dyslexia showed more visual errors and analogy errors, and children with deep dyslexia showed more semantic errors and selective errors.

This paper investigates the importance of the phonological coding system (PCS) by examining the possible moderation effect of knowledge of the PCS on the predictiveness of auditory temporal processing (ATP) for Chinese character reading. Eighty typically developing Chinese children in the first and second grades in Taiwan were recruited, and various cognitive and literacy ability tasks were administered. The results revealed that knowledge of the PCS served as a significant moderator of the association between ATP and Chinese character reading, that is, the significant prediction from ATP to Chinese character reading was observed only in those with high knowledge of the PCS but not those with low knowledge of the PCS. Additionally, we further demonstrated diverse ability levels in phonological processing as it contributes to Chinese character reading among individuals with higher and lower knowledge of the PCS. Specifically, ATP as well as phonological awareness significantly predicted Chinese character reading for those with high knowledge of the PCS, while only verbal short-term memory served as a significant predictor of Chinese character reading for those with low knowledge of the PCS. Our results show that individuals with different levels of knowledge of the PCS may demonstrate different ability levels in phonological processing in their Chinese character reading, which suggests that the need for teaching approaches suited to students with diverse learning experiences should be acknowledged. • Auditory temporal processing can only conditionally contribute to Chinese reading • Knowledge of phonological coding system serves as the significant moderator. • Auditory temporal processing could predict Chinese character reading for higher group • Phonological awareness as well is a significant predictor for higher group • Only verbal short-term memory served as a significant predictor for lower group [ABSTRACT FROM AUTHOR]
