Here we test the hypothesis that fluctuations in subjective reports of mind wandering over time-on-task are associated with fluctuations in performance over time-on-task. In Study 1, we employed a singleton search task and found that performance did not differ prior to on- and off-task reports, nor did individual differences in mind wandering predict differences in performance (so-called standard analytic methods). Importantly however, we find that fluctuations in mind wandering over time are strongly associated with fluctuations in behavior. In Study 2, we provide a replication of the relation between mind wandering and performance over time found in Study 1, using a Flanker interference task. These data indicate (1) a tight coupling between mind wandering and performance over time and (2) that a temporal-analytic approach can reveal effects of mind wandering on performance in tasks where standard analyses fail to do so. The theoretical and methodological implications of these findings are discussed.
在此，我们检验这样一个假设：在执行任务过程中，随时间推移，思维游荡主观报告的波动与任务执行表现随时间的波动相关。在研究1中，我们采用了单目标搜索任务，发现任务执行前和任务报告前后的表现并无差异，思维游荡的个体差异也无法预测表现上的差异（即所谓的标准分析方法）。然而，重要的是，我们发现随时间推移，思维游荡的波动与行为波动密切相关。在研究2中，我们使用侧翼干扰任务，对研究1中发现的思维游荡与任务执行表现随时间的关系进行了重复验证。这些数据表明：（1）思维游荡与任务执行表现随时间紧密相关；（2）在标准分析无法揭示的情况下，时间分析方法能够揭示思维游荡对任务执行表现的影响。我们将讨论这些发现的理论和方法学意义。
