Mind wandering is a state in which our mental focus shifts toward task-unrelated thoughts. Although it is known that mind wandering has a detrimental effect on concurrent task performance (e.g., decreased accuracy), its effect on executive functions is poorly studied. Yet the latter question is relevant to many real-world situations, such as rapid stopping during driving. Here, we studied how mind wandering would affect the requirement to subsequently stop an incipient motor response. In healthy adults, we tested whether mind wandering affected stopping and, if so, which component of stopping was affected: the triggering of the inhibitory brake or the implementation of the brake following triggering. We observed that during mind wandering, stopping latency increased, as did the percentage of trials with failed triggering. Indeed, 67% of the variance of the increase in stopping latency was explained by increased trigger failures. Thus, mind wandering primarily affects stopping by affecting the triggering of the brake.
思维漫游是一种状态，在这种状态下，我们的注意力会从任务转移到与任务无关的想法上。虽然已经知道思维漫游会对当前任务的表现产生不利影响（例如，准确性降低），但它对执行功能的影响还没有得到很好的研究。然而，后一个问题与许多现实情况有关，例如在驾驶过程中快速停车。在这里，我们研究了思维漫游会如何影响随后停止初始运动反应的要求。在健康成年人中，我们测试了思维漫游是否会影响停止，如果是，那么停止的哪个组件会受到影响：抑制刹车的触发还是触发后的刹车实施。我们观察到，在思维漫游期间，停止潜伏期增加，触发失败的试验百分比也增加。事实上，停止潜伏期增加的 67%的方差可以用触发失败的增加来解释。因此，思维漫游主要通过影响刹车的触发来影响停止。
