Orthographic Processing of Developmental Dyslexic Children in China: Evidence from an Event-Related Potential Study.

Objective: This study aimed to explore the orthographic processing of simplified Chinese characters in developmental dyslexic children in Kashgar, Xinjiang, China, and provide a theoretical basis for intervention strategies for developmental dyslexia in Chinese.

Methods: Using event-related potential (ERP) measures, 18 developmental dyslexic children and 23 typically developing children performed a character decision task with three types of stimuli: real characters (RCs), pseudocharacters (PCs), and noncharacters (NCs).

Results: Behavioral results showed that the control children displayed a faster and higher accurate performance than the dyslexic children across PCs and NCs.

Association between SNPs and risk of dyslexia: a meta-analysis.

The aetiology of developmental dyslexia (DD) is complex; although candidate genes have been suggested, the molecular mechanism and risk factors remain unknown. The gene is functionally related to neuronal migration and axon growth, and several studies have examined associations between polymorphisms with DD, but the results remain inconsistent. The sample size affects the results of meta-analysis.
