先前的研究表明，与任务无关的启动会触发眼动。这种视觉捕捉通常不受有意识意识的影响。本研究使用事件相关脑电位来研究如何检测，评估和补偿这种眼动错误，以及错误的意识是否在任何这些处理阶段发挥了作用。结果表明，错误检测和纠正的早期过程（由错误相关的负性和顶叶N1表示）不直接受主观意识的错误。相反，它们似乎受到正确和错误眼跳编程之间的时间重叠程度的调节。我们发现，只有一个较后的组成部分（错误相关的积极性[Pe]）是通过意识到错误的眼球运动来调节的。我们认为，对眼球运动捕获的意识主要取决于后面的过程。
Previous research has shown that task-irrelevant onsets trigger an eye movement in their direction. Such oculomotor capture is often impervious to conscious awareness. The present study used event-related brain potentials to examine how such oculomotor errors are detected, evaluated, and compensated for and whether awareness of an error played a role at any of these stages of processing. The results show that the early processes of error detection and correction (as represented by the error-related negativity and the parietal N1) are not directly affected by subjective awareness of making an error. Instead, they seem to be modulated by the degree of temporal overlap between the programming of the correct and erroneous saccade. We found that only a later component (the error-related positivity [Pe]) is modulated by awareness of making an erroneous eye movement. We propose that awareness of oculomotor capture primarily depends on this later process.
