Abstract：
UNASSIGNED: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an \"at risk\" dimension for ADHD.
UNASSIGNED: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task, a revised Go/NoGo task, and the AX-continuous performance test (AX-CPT).
UNASSIGNED: Children with higher levels of hyperactivity displayed: (1) significantly prolonged stop signal reaction time (SSRT) in the modified stop-signal anticipation task; (2) no notable differences in commission errors in the revised Go/NoGo task; (3) increased reaction time (RT) in stop-signal task and Go/NoGo task with increased probabilities of stop or NoGo signal; and (4) positive proactive behavioral index scores in AX-CPT.
UNASSIGNED: The results suggested that children with heightened hyperactivity exhibited impaired reactive control, especially for responses already underway, but preserved proactive control. Further studies concerning these children are warranted.

摘要：
■为了检查不同程度多动症儿童的认知控制缺陷的表现，ADHD的“有风险”维度。
■一组多动症儿童（N=40）和另一组多动症儿童（N=38）进行了修改的停止信号预测任务，修改后的Go/NoGo任务，以及AX-连续性能测试(AX-CPT)。
■显示的多动症儿童：（1）在修改后的停止信号预期任务中，停止信号反应时间（SSRT）显着延长；（2）在修改后的Go/NoGo任务中，佣金错误没有显着差异；（3）停止信号任务和Go/NoGo任务的反应时间（RT）增加，停止或NoGo信号的概率增加；（4）积极的CPAX行为指数
■结果表明，多动症儿童表现出反应控制受损，特别是对于已经在进行的回应，但保持了主动控制。有必要对这些儿童进行进一步的研究。
