The visual attention span deficit in Chinese children with reading fluency difficulty.
Chinese children who read slowly miss more symbols when many appear at once, pointing to a visual attention span weakness.
01Research in Context
What this study did
Zhao et al. (2018) looked at how kids with reading fluency trouble take in many Chinese symbols at once.
They used a quasi-experimental design. Kids saw five symbols flash at once and had to pick the one that matched.
All children spoke Chinese and lived in China. The study did not give a diagnosis like dyslexia.
What they found
Children who read slowly scored lower on the many-symbol task.
Their eyes also landed on different spots than good readers.
Slower single-character reading went hand-in-hand with this wider visual attention span deficit.
How this fits with other research
Cheng et al. (2021) extends this work. They tested kids with official dyslexia and found the same visual attention gap plus phonology gaps.
Evans et al. (1994) gives a baseline. Typical kids’ eye-movement attention keeps improving through teen years. This shows the Chinese readers’ gap is not just slow development.
Schertz et al. (2016) shifts the lens to adults and English script. They found time-based memory deficits in dyslexia, adding more proof that reading trouble carries multiple attention-memory burdens.
Why it matters
If a Chinese-speaking client reads slowly, test how many symbols they can process at once. A quick five-symbol matching task can flag a visual attention span deficit. Pair this with phonology checks as Cheng et al. (2021) did. Targeting wider symbol groups in reading drills may boost fluency more than single-letter work.

03Original abstract
With reading development, some children fail to learn to read fluently. However, reading fluency difficulty (RFD) has not been fully investigated. The present study explored the underlying mechanism of RFD from the aspect of visual attention span. Fourteen Chinese children with RFD and fourteen age-matched normal readers participated. The visual 1-back task was adopted to examine visual attention span. Reaction time and accuracy were recorded, and relevant d-prime (d') scores were computed. Results showed that children with RFD exhibited lower accuracy and lower d' values than the controls did in the visual 1-back task, revealing a visual attention span deficit. Further analyses on d' values revealed that the attention distribution seemed to exhibit an inverted U-shaped pattern without lateralization for normal readers, but a W-shaped pattern with a rightward bias for children with RFD, which was discussed based on between-group variation in reading strategies. Results of the correlation analyses showed that visual attention span was associated with reading fluency at the sentence level for normal readers, but was related to reading fluency at the single-character level for children with RFD. The different patterns in correlations between groups revealed that visual attention span might be affected by the variation in reading strategies. The current findings extend previous data from alphabetic languages to Chinese, a logographic language with a particularly deep orthography, and have implications for reading-dysfluency remediation.
