Physically salient stimuli are difficult to ignore, frequently eliciting fixations even when they are known to be task-irrelevant. A recent study demonstrated that distractor fixation-contingent auditory feedback was highly effective in reducing the frequency of fixations on such stimuli. The present study explores more specifically what it is about feedback that makes it effective in curbing oculomotor behavior. In one experiment, we removed the immediacy of the feedback by informing participants after each trial via textual feedback if they had fixated the distractor. A comparable reduction in the frequency of oculomotor capture was observed. In a second experiment, we only provided summary feedback concerning the frequency of oculomotor capture after each block of trials. Not only were the benefits of feedback again robustly comparable, but a benefit was observed even in the first block before any feedback had actually been presented. Simply knowing that the frequency of distractor fixations was being monitored was sufficient to substantially reduce the frequency of oculomotor capture. Interestingly, trial-level feedback predominantly reduced the frequency of capture by slowing oculomotor responses, reflecting a speed-accuracy tradeoff, whereas block-wise feedback resulted in a reduction in the frequency of capture with saccadic reaction time equated, reflecting a bona fide improvement in task performance. Our findings have implications for our understanding of the role of motivation, strategy, and selection history in oculomotor control.

身体上显着的刺激很难被忽视，即使已知它们与任务无关，它们也经常引起注视。最近的一项研究表明，干扰物固定条件听觉反馈在减少对此类刺激的固定频率方面非常有效。本研究更具体地探讨了反馈是什么使其有效地抑制动眼神经行为。在一项实验中，我们通过在每次试验后通过文本反馈通知参与者是否已固定干扰物来消除反馈的即时性。观察到动眼神经捕获频率的可比降低。在第二个实验中，我们只提供了关于每组试验后动眼神经捕获频率的总结反馈。不仅反馈的好处再次具有强大的可比性，但即使在第一个区块中，在实际提出任何反馈之前，也观察到了好处。仅仅知道干扰器固定的频率被监测就足以显着降低动眼神经捕获的频率。有趣的是，试验级反馈主要通过减慢动眼神经反应来降低捕捉频率，反映了速度-准确性的权衡，而块状反馈导致捕捉频率降低，与扫视反应时间相等，反映了真正的改善任务表现。我们的研究结果对我们理解动眼神经控制中动机、策略和选择历史的作用具有重要意义。仅仅知道干扰器固定的频率被监测就足以显着降低动眼神经捕获的频率。有趣的是，试验级反馈主要通过减慢动眼神经反应来降低捕捉频率，反映了速度-准确性的权衡，而块状反馈导致捕捉频率降低，与扫视反应时间相等，反映了真正的改善任务表现。我们的研究结果对我们理解动眼神经控制中动机、策略和选择历史的作用具有重要意义。仅仅知道干扰器固定的频率被监测就足以显着降低动眼神经捕获的频率。有趣的是，试验级反馈主要通过减慢动眼神经反应来降低捕捉频率，反映了速度-准确性的权衡，而块状反馈导致捕捉频率降低，与扫视反应时间相等，反映了真正的改善任务表现。我们的研究结果对我们理解动眼神经控制中动机、策略和选择历史的作用具有重要意义。反映了速度-准确度的权衡，而逐块反馈导致捕获频率降低，与扫视反应时间相等，反映了任务性能的真正改善。我们的研究结果对我们理解动眼神经控制中动机、策略和选择历史的作用具有重要意义。反映了速度-准确度的权衡，而逐块反馈导致捕获频率降低，与扫视反应时间相等，反映了任务性能的真正改善。我们的研究结果对我们理解动眼神经控制中动机、策略和选择历史的作用具有重要意义。
