在词汇判断任务中，使用错误/正确相关的负波、反应锁定成分的诱发反应电位和刺激锁定成分N100来比较熟练读者和补偿和非补偿阅读困难青少年读者的错误检测监控。结果显示，在错误投射前，所有组的N100波幅普遍增加；与其他两组相比，未补偿阅读障碍组的错误/正确相关负波幅度显著降低；较小的错误相关负波与较多的解码错误、较低的工作记忆分数和较慢的神经心理单元的处理速度相关。基于前人提出的错误检测机制是执行功能的一个子成分的假设，本文探讨了阅读障碍非补偿性读者阅读能力差的原因可能是执行能力差。这些发现可以作为一个平台，为有阅读障碍的个人提供基于高管的诊断和培训。
Error/correct-related negativities, response-locked components of the evoked response potential, and N100, a stimulus-locked component, were used to compare error detection monitoring in skilled readers and in compensated and noncompensated dyslexic adolescent readers during a lexical decision task. Results showed a general increase in N100 amplitudes prior to error commission in all groups; a significant decrease in error/correct-related negativity amplitudes in the noncompensated dyslexics compared with the other 2 groups; and smaller error-related negativity correlated with a higher number of decoding errors, lower working memory scores, and lower speed of processing in the neuropsychological battery. Based on the hypothesis in previous studies that the error detection mechanism is a subcomponent of executive functions, the possibility that poor executive ability underlies poor reading skills in the noncompensated dyslexic readers is discussed. These findings can be used as a platform for executive-based diagnosis and training for individuals with reading disabilities.
