Chinese handwriting performance of primary school children with dyslexia.
A quick Chinese character copy test spots dyslexia by slow, error-filled writing.
01Research in Context
What this study did
The team asked primary-school children with dyslexia to copy 90 Chinese characters.
They timed each child, measured letter size, and counted mistakes.
Then they compared the scores to children without dyslexia.
What they found
Kids with dyslexia wrote more slowly, made more errors, and their letters were bigger and shakier.
Speed and accuracy together spotted dyslexia over 70 percent of the time.
A short copy task can flag risk without a long test battery.
How this fits with other research
Cheng-Lai et al. (2013) looked at the same group and found slow writing links to poor rapid naming and weak eye movements.
Lee et al. (2014) saw almost the same writing problems in Taiwanese children with ADHD.
The pattern looks alike, but the cause differs: dyslexia stems from language wiring, ADHD from focus and impulse control.
Capio et al. (2013) showed children with DCD pause more, not move slower—so watch for freeze-ups, not just sluggish pens.
Why it matters
If you work with Chinese-speaking students, give a one-minute character-copy probe. Slow, sloppy copies warn of dyslexia and spare kids longer tests. Pair the probe with rapid-naming and visual-motor checks to find the true weak link.

03Original abstract
The aim of this study was to investigate the Chinese handwriting performance of typical children and children with dyslexia, and to examine whether speed and accuracy of handwriting could reliably discriminate these two groups of children. One hundred and thirty-seven children with dyslexia and 756 typical children were recruited from main stream primary schools for the study. They were requested to copy 90 Chinese characters using the Chinese Handwriting Assessment Tool (CHAT) jointly developed by a project team from two universities in Hong Kong. The process of handwriting was recorded and the stroke errors in writing were analyzed using the CHAT system. Results indicated that children with dyslexia wrote significantly slower, with greater average character size and variation in size (p<.05) than the typical children of same age group. They also wrote with significantly lower accuracy (p<.05). Commonly observed writing errors among the Dyslexic group were missing strokes and concatenated strokes. From the discriminant analysis, it was found that writing speed and accuracy were satisfactory discriminators that could discriminate students into the two groups, with reasonably good classification accuracy of over 70% for every grade. The results were discussed with theoretical implications in relation to fine motor skills, kinesthetic abilities, visual perceptual skills, and the demand of written tasks in school.
