This study compared children with ADHD, reading disorder (RD), ADHD+RD, and control children on behavioural (post-error slowing and post-error accuracy) and event-related potential (Ne and Pe) measures of error monitoring. Children with ADHD did not differ from children without ADHD in post-error slowing but showed less post-error accuracy enhancement, as evidenced by a higher proportion of double-errors. We found a smaller Ne but normal Pe amplitude in children with RD, and a smaller Pe but normal Ne amplitude in children with ADHD. Children from the comorbid group showed both a smaller Ne and a smaller Pe amplitude, which suggests that they showed the additive combination of the deficits found in both separate disorders. The results of the present study suggest that it might be important to control for the presence of comorbid RD when examining error monitoring in ADHD and that various measures of post-error adaptation should be included.
本研究比较了 ADHD 儿童、阅读障碍（RD）儿童、ADHD+RD 儿童和对照组儿童在行为（错误后减速和错误后准确性）和事件相关电位（Ne 和 Pe）方面的错误监测。ADHD 儿童与无 ADHD 儿童的错误后减速没有差异，但表现出较少的错误后准确性提高，表现为双错误的比例更高。我们发现 RD 儿童的 Ne 较小，Pe 振幅正常，而 ADHD 儿童的 Pe 较小，Ne 振幅正常。来自共病组的儿童表现出 Ne 和 Pe 振幅都较小，这表明他们表现出两种单独疾病缺陷的累加组合。本研究结果表明，在检查 ADHD 中的错误监测时，可能需要控制共患 RD 的存在，并且应该包括各种错误后适应的测量。
