发展性阅读障碍的视觉注意广度技能
摘要
<p id="C2">A specific deficit in individuals with developmental dyslexia has been repeatedly found in many tasks that had one aspect in common, that was, the processing of multiple visual elements in parallel. This skill is regarded as the visual attention span. This paper reviews the relevant literature about the visual attention span of the dyslexics in the contexts of alphabetic languages and Chinese. Currently, the relevant findings have been still in debate, and the inconsistent results may be attributed to the differences in orthographic depth of the background language and the participants’ ages. Future studies can further explore the relationship between visual attention span and reading disability through the methods of the intervention study and cross-language comparison; meanwhile the neural mechanisms underlying the visual attention span of Chinese individuals with dyslexia could be investigated by the neuroimaging techniques.
