Classifying Chinese children with dyslexia by dual-route and triangle models of Chinese reading.
Chinese dyslexic readers rarely fit one neat subtype—map mixed error patterns plus visual and auditory markers for better assessment.
01Research in Context
What this study did
Wang et al. (2014) looked at how Chinese children with dyslexia make reading errors.
They used two brain-based ideas: the dual-route model and the triangle model.
Each model predicts different error types, so the team sorted kids by the mistakes they made.
What they found
Most dyslexic readers did not fit neatly into one subtype.
Over half showed mixed error patterns, not pure phonological, surface, or deep profiles.
This means single-label diagnoses can miss the real picture.
How this fits with other research
Tong et al. (2019) extends this work. They found Chinese dyslexic kids also struggle with visual statistical learning and orthographic rules.
Wang et al. (2019) adds auditory markers. Poor FM sweep detection links to weak tone awareness and worse character reading.
Park et al. (2013) seems to clash. They saw no phonological effect on reading in either younger or older dyslexic students. The difference is method: Heeyoung used broad phonological tests, while Li-Chih used fine-grained error analysis that caught smaller phonological slips.
Why it matters
When you test a Chinese-speaking child who reads poorly, record the exact errors, not just accuracy.
Look for phonological, surface, and deep patterns in the same child.
Then check visual pattern learning and auditory tone tasks to build a full profile before you plan help.

03Original abstract
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.
