走神不仅普遍存在，而且对任务表现有害。因此，识别与这种非任务状态相关的隐蔽生理措施可以为走神理论提供信息，并导致提高任务注意力的干预措施。虽然先前的研究表明瞳孔扩张（PD）可能在工作状态和非任务状态之间有所不同，但没有研究表明，当受试者报告从任务中脱离时，瞳孔扩张（PD）是否会系统性地发生变化，这是开发有用的走神预测算法的关键步骤。在目前的研究中，PD是在参与者一次读一个单词时进行测量的。使用标准思维探测方法评估阅读过程中的自发走神。结果显示，非任务阅读前的PD高于任务阅读前的PD。这一新发现的注意力瞬间波动与PD之间的关系为未来的创新提供了希望，即利用PD的这些系统变化来预测和更好地控制走神。
Mind-wandering is both pervasive and detrimental to task performance. As such, identifying covert physiological measures that are associated with this off-task state could inform theories of mind-wandering and lead to interventions that improve task focus. Although previous work suggests that pupil dilation (PD) may vary between on- and off-task states, no studies have examined whether PD systematically varies within a subject as they report becoming disengaged from a taska key step in developing useful mind-wandering prediction algorithms. In the present study, PD was measured while participants advanced through a passage one word at a time. Spontaneous mind-wandering was assessed during reading using standard thought probe methodology. Results revealed higher PD prior to off-task than prior to on-task reading. This newly discovered relationship between momentary fluctuations of attention and PD offers promise for future innovations that use these systematic changes in PD to predict and better control mind-wandering.
