Research on brain activity involved in error detection and correction

在这项研究中，我们研究了在连续认知任务中参与反应速度监控的大脑活动，在连续认知任务中，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theta频段脑电功率(4~7赫兹)的增加。第二，实验结果表明，任务绩效不仅影响任务绩效，而且影响任务绩效，也影响任务绩效。此外，研究还表明，解决试题的动机可能也会影响theta频段的脑电功率。

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.
