Recent studies have shown that mind-wandering (MW) is associated with changes in eye movement parameters, but have not explored how MW affects the sequential pattern of eye movements involved in making sense of complex visual information. Eye movements naturally unfold over time and this process may reveal novel information about cognitive processing during MW. The current study used Recurrence Quantification Analysis (Anderson, Bischof, Laidlaw, Risko, & Kingstone, 2013) to describe the pattern of refixations (fixations directed to previously inspected regions) during MW. Participants completed a real-world scene encoding task and responded to thought probes assessing intentional and unintentional MW. Both types of MW were associated with worse memory of the scenes. More important, RQA showed that scanpaths during unintentional MW were more repetitive than during on-task episodes, as indicated by a higher recurrence rate and more stereotypical fixation sequences. This increased repetitiveness suggests an adaptive response to processing failures through reexamining previous locations. Moreover, this increased repetitiveness contributed to fixations focusing on a smaller spatial scale of the stimuli. Finally, we were also able to validate several traditional measures: both intentional and unintentional MW were associated with fewer and longer fixations; eye-blinking increased numerically during both types of MW but the difference was only significant for unintentional MW. Overall, the results advanced our understanding of how visual processing is affected during MW by highlighting the sequential aspect of eye movements.

真实世界场景感知中走神的再固定模式。

最近的研究表明，走神 (MW) 与眼球运动参数的变化有关，但尚未探讨 MW 如何影响涉及理解复杂视觉信息的眼球运动的顺序模式。随着时间的推移，眼球运动自然展开，这个过程可能会揭示关于 MW 期间认知处理的新信息。当前的研究使用复发量化分析（Anderson、Bischof、Laidlaw、Risko 和 Kingstone，2013 年）来描述 MW 期间的再注视模式（注视到先前检查过的区域）。参与者完成了现实世界的场景编码任务，并对评估有意和无意 MW 的思想探索做出了回应。两种类型的 MW 都与较差的场景记忆有关。更重要，RQA 显示无意 MW 期间的扫描路径比执行任务期间的扫描路径更重复，如更高的复发率和更多刻板的固定序列所示。这种增加的重复性表明通过重新检查以前的位置对处理失败的适应性反应。此外，这种增加的重复性有助于将注意力集中在较小的刺激空间尺度上。最后，我们还能够验证几种传统的测量方法：有意和无意的 MW 都与更少和更长的注视有关；在两种类型的 MW 期间，眨眼在数值上都有所增加，但差异仅对无意 MW 显着。总体而言，结果通过突出眼球运动的顺序方面促进了我们对 MW 期间视觉处理如何影响的理解。
