Midfrontal theta is widely observed in situations with increased demand for cognitive control, such as monitoring response errors. It also plays an important role in the cognitive control involved in memory, supporting processes like the binding of single items into a memory representation or encoding contextual information. In the current study, we explored the link between midfrontal theta and error-related memory. To this end, we recorded EEG from 31 participants while they performed a modified flanker task. Their memory for the errors made during the task was assessed after each experimental block, and its relationship with error-related midfrontal theta effects was investigated. We have replicated the error-related increase in midfrontal theta power, reported in previous literature. However, this error-related theta effect could not predict subsequent memory of the committed errors. Our findings add to a growing literature on the prefrontal cortex-guided control process in error monitoring and memory.
额中回θ波在认知控制需求增加的情况下广泛存在，比如监测反应错误时。它在涉及记忆的认知控制中也发挥着重要作用，支持诸如将单个项目绑定到记忆表征或编码情境信息等过程。在本研究中，我们探究了额中回θ波与错误相关记忆之间的联系。为此，我们记录了31名参与者在执行改良侧翼任务时的脑电图。在每个实验块后评估他们对任务期间所犯错误的记忆，并研究其与错误相关的额中回θ波效应的关系。我们重复了先前文献中报道的额中回θ波功率与错误相关的增加。然而，这种与错误相关的θ波效应无法预测对所犯错误的后续记忆。我们的研究结果为前额叶皮质在错误监测和记忆中引导控制过程的文献增添了内容。
