In this study, we investigated brain activity involved in monitoring of response speed during continuous cognitive task, in which subjects were instructed to respond as fast and correct as possible. First, increase in theta-band EEG power (4～7Hz) was observed in slower responded trials. Second, it was shown that the theta-band power was modulated by the task performance not only in the ongoing trials but also in the previous trials. In addition, it was suggested that the theta-band EEG power might also be affected by motivation in solving trials as fast as possible.

在这项研究中，我们研究了连续认知任务期间涉及监测反应速度的大脑活动，其中受试者被指示尽可能快速和正确地做出反应。首先，在反应较慢的试验中观察到θ波段脑电图功率（4～7Hz）增加。其次，事实证明，theta 波段功率不仅在正在进行的试验中而且在之前的试验中都受到任务表现的调节。此外，有人认为，theta 波段脑电图功率也可能受到尽快解决试验的动机的影响。
