Stroop interference in children with developmental dyslexia An event-related potentials study

Previous studies have identified inhibitory deficits in dyslexic children, but we have little understanding of their neural mechanisms, especially for Chinese children with developmental dyslexia. We used a double-blind controlled trial to study the electroencephalogram responses of dyslexic and non-dyslexic children when performing the Stroop color-word test. Behavioral data showed differences in response time and accuracy between the 2 groups. In the event-related potentials (ERP) results, dyslexic children displayed larger P2 and P3b on congruent trials, while non-dyslexic children displayed larger P2 and P3b on incongruent trials, the 2 groups showed opposite brain activation patterns on the Stroop test. Dyslexic children have poor inhibitory function, and this poor inhibition may be related to their abnormal brain activation patterns.

Automated summary

Previous studies have found inhibitory deficits in dyslexic children, with differences in brain activation patterns between dyslexic and non-dyslexic children during the Stroop color-word test. Dyslexic children have poorer inhibitory function which may be related to their abnormal brain activation patterns.
