Inhibitory Defects in Chinese Children with Developmental DyslexiaAuthor(s): Enguo Wang, Wu Kai, Wangchao, Tian Yuan
There is a big difference between Chinese and English. There are quite a few studies on the neural mechanism of Chinese developmental dyslexia. As the reading process is inseparable from working memory, inhibition, and other higher cognitive processes, the deep cognitive processing defects that are associated with dyslexia may be due to defective distraction inhibition systems. We used event-related potential technology to explore the source of negative priming effects in children with developmental dyslexia and in a group of healthy children for comparison. These results indicate that there are deficits in distraction inhibition in children with developmental dyslexia. In terms of the time course of processing, inhibition deficits in the dyslexia group appeared during early-stage cognition selection and lasted through the response selection phase. The results of our study may help further our understanding of the intrinsic causes of developmental dyslexia.
