Impact of visual processing skills on reading ability in Chinese deaf children.
Visual-orthographic skill is the middle step between basic vision and reading for Chinese deaf children—screen it early.
01Research in Context
What this study did
Hao et al. (2021) asked which visual skills help Chinese deaf children read. They tested kids in grades 2-6. The team measured visual-graphic skill, visual-orthographic skill, and reading ability.
They used mediation tests to see if orthographic skill carries the effect. Word-segmentation skill was also checked but did not act as a mediator.
What they found
Both visual-graphic and visual-orthographic scores predicted reading scores. Visual-orthographic skill worked like a bridge: it carried most of the effect from basic visual skill to reading.
Word-segmentation skill did not bridge the gap. The model fit was strong and positive.
How this fits with other research
The result extends Domínguez et al. (2014). That study showed deaf adults still lean on orthographic and keyword tricks. Ying et al. show the roots of that habit start in childhood.
There is an apparent contradiction with Blom et al. (2017). They found no extra benefit from hypertext for deaf students. Ying’s team, however, says visual-orthographic skill matters a lot. The gap is explained by task: Helen looked at text format, Ying looked at underlying visual skill. Different questions, no real clash.
Cai et al. (2019) from the same lab found vocabulary beats phonology for Chinese deaf readers. The new paper adds that visual-orthographic skill is another must-track variable.
Why it matters
If you assess a Chinese deaf learner, add a quick visual-orthographic task such as radical matching. A low score flags reading risk even if vocabulary looks fine. Pair later vocabulary drills with visual-orthographic games to shore up the mediator. The same screener idea may help other logographic languages.

03Original abstract
BACKGROUND: Reading activity involves visual processing in nature. Compared with hearing people, visual processing may be more critical for deaf people. However, much less research has explored the impact of visual processing on the reading ability of deaf children, and the mechanism underlying this relationship is unclear. AIMS: This study aimed to examine whether and how visual processing skills predict reading ability in elementary school deaf children in China. METHODS AND PROCEDURES: A total of 118 Chinese deaf children (mean age = 14.60 years) from grades 4-6 were tested on the tasks of visual-graphic processing, visual-orthographic processing, word segmentation, reading comprehension, and reading fluency. OUTCOMES AND RESULTS: The results showed that after chronological age was controlled, visual-graphic processing and visual-orthographic processing significantly predicted Chinese deaf children's reading ability. Specifically, visual-orthographic processing played a mediating role in the effect of visual-graphic processing on reading ability, whereas word segmentation played a mediating role in the effect of visual-orthographic processing on reading ability. However, the mediating role of word segmentation, as well as the chain mediating effect of visual-orthographic processing and word segmentation in the influence of visual-graphic processing on reading ability, were not significant. CONCLUSIONS AND IMPLICATIONS: These findings emphasized the importance of visual processing skills in reading activity and offered potential mechanisms underlying the contribution of visual processing skills to reading ability in Chinese deaf children.
