Laboratory electroencephalography (EEG) studies have already provided important insights into the neuronal mechanisms of performance monitoring. However, to our knowledge no study so far has examined neuronal correlates of performance monitoring using an ecologically valid task outside a typical laboratory setting. Therefore, we examined midfrontal theta and the feedback-related negativity (FRN) using mobile EEG in a physical shooting task within an ecologically valid environment with highly dynamical visual feedback. Participants shot a target using a toy gun while moving and looking around freely. Shots that missed the target evoked stronger midfrontal theta activity than hits and this response was rather phase-unlocked. There was no difference between misses and hits in the FRN. The results raise the question whether the absence of certain ERP components like the FRN could be due to methodological reasons or to the fact that partially different neuronal processes may be activated in the laboratory as compared to more ecologically valid tasks. Overall, our results indicate that crucial neurocognitive processes of performance monitoring can be assessed in highly dynamic and ecologically valid settings by mobile EEG.

以生态有效性为目标——玩具枪射击任务中的中额θ振荡

实验室脑电图 (EEG) 研究已经为性能监测的神经元机制提供了重要的见解。然而，据我们所知，到目前为止，还没有研究使用典型实验室环境之外的生态有效任务来检查性能监测的神经元相关性。因此，我们在具有高度动态视觉反馈的生态有效环境中的物理射击任务中使用移动脑电图检查了中额 theta 和反馈相关的负性 (FRN)。参与者在自由移动和环顾四周时使用玩具枪射击目标。未击中目标的击球比击球更能引起中额叶的 theta 活动，而且这种反应是相位解锁的。FRN 中未命中和命中之间没有区别。结果提出了一个问题，如 FRN 等某些 ERP 组件的缺失是否可能是由于方法学原因，还是由于与更生态有效的任务相比，在实验室中可能会激活部分不同的神经元过程这一事实。总的来说，我们的结果表明，可以通过移动脑电图在高度动态和生态有效的环境中评估性能监测的关键神经认知过程。
