我们研究了ADHD和控制儿童在需要抑制运动反应的任务中的错误监测。各组间比较成功（停止）和失败（未停止）抑制后的减缓程度。我们还测量了抑制反应所需的时间（停止信号反应时间，SSRT）。与对照组相比，ADHD参与者在不间断的反应后放慢了速度。阅读、对立、行为或焦虑障碍、性别或ADHD亚型的共病并没有减慢。不间断反应后的反应减慢是轻微的，尽管与ADHD的总症状和年龄显著相关。ADHD参与者的SSRT时间明显长于对照组，但SSRT与慢速无显著相关。注意缺陷多动障碍中错误监测的明显缺陷及其与注意缺陷多动障碍中观察到的抑制缺陷的独立性对注意缺陷多动障碍的执行控制模型、与该障碍相关的表现问题以及执行控制的组成理论具有启示意义。
We studied error monitoring in ADHD and control children in a task requiring inhibition of a motor response. The extent of slowing following successful (stopped) and failed (nonstopped) inhibition was compared across groups. We also measured the time required to inhibit a response (stop signal reaction time, SSRT). Compared to controls, ADHD participants slowed less following nonstopped responses. Slowing did not vary with comorbid reading, oppositional, conduct or anxiety disorder, sex or ADHD subtype. Slowing after nonstopped responses was marginally, although significantly correlated with total ADHD symptoms and with age. ADHD participants had significantly longer SSRT than controls, but SSRT was not significantly correlated with slowing. The apparent deficit in error monitoring in ADHD and its independence from the inhibition deficit observed in ADHD has implications for executive control models of ADHD, performance problems associated with the disorder and for component theories of executive control.
