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监测反应速度的大脑活动，在这些任务中，受试者被指示尽可能快速和正确地做出反应。首先，在反应较慢的实验中，观察到theta波段脑电图功率（4~7Hz）的增加。第二，实验结果表明，不仅在正在进行的实验中，而且在已经完成的实验中，波段功率都受到任务表现的调制。此外，在尽可能快的解题过程中，动机也可能影响脑电图功率。

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.
