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.

瞄准生态有效性——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，还没有研究在典型的实验室环境之外使用生态有效的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，在物理拍摄任务中使用移动脑电图检查了中额 theta 和反馈相关负性 (FRN)。参与者在自由移动和环顾四周的同时使用玩具枪射击目标。与命中相比，未命中目标的射门会引起更强的中额 theta 活动，并且这种反应是相位解锁的。FRN中的未命中和命中之间没有区别。结果提出了一个问题，是否缺少某些 ERP 组件（如 FRN）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，实验室中可能激活了部分不同的神经元过程。总体而言，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关键的神经认知过程监测。
