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.
背景
阅读活动本质上涉及视觉处理。与听力正常的人相比，视觉处理对于聋人可能更为关键。然而，对于视觉处理如何影响聋童的阅读能力，以及这种关系的潜在机制，研究甚少。
目的
本研究旨在探讨视觉处理技能是否以及如何预测中国小学聋童的阅读能力。
方法和程序
共有 118 名来自 4-6 年级的中国聋童（平均年龄为 14.60 岁）接受了视觉-图形处理、视觉-正字法处理、分词、阅读理解和阅读流畅性任务的测试。
结果
结果表明，在控制了实际年龄后，视觉-图形处理和视觉-正字法处理显著预测了中国聋童的阅读能力。具体而言，视觉-正字法处理在视觉-图形处理对阅读能力的影响中起中介作用，而分词在视觉-正字法处理对阅读能力的影响中起中介作用。然而，分词的中介作用以及视觉-正字法处理和分词在视觉-图形处理对阅读能力影响中的链式中介作用并不显著。
结论和意义
这些发现强调了视觉处理技能在阅读活动中的重要性，并为视觉处理技能对中国聋童阅读能力的贡献提供了潜在的机制。
