Attention and mind wandering are often seen as anticorrelated. However, both attention and mind wandering are multi-component processes, and their relationship may be more complex than previously thought. In this study, we tested the interference of different types of thoughts as measured by a Thought Identification Task - TIT (on task thoughts, task related interference thoughts, external distractions, stimulus independent and task unrelated thoughts) on different components of the attention network system - ANT (alerting, orienting, executive). Results show that, during the ANT, individuals were predominantly involved in task related interference thoughts which, along with external distractors, significantly impaired their performance accuracy. However, mind wandering (i.e., stimulus independent and task unrelated thoughts) did not significantly interfere with accuracy in the ANT. No significant relationship was found between type of thoughts and alerting, orienting, or executive effects in the ANT. While task related interference thoughts and external distractions seemed to impair performance on the attention task, mind wandering was still compatible with satisfactory performance in the ANT. The present results confirmed the importance of differentiating type of "out of task" thoughts in studying the relationship between though distractors and attention.
注意力和思绪游走通常被视为负相关。然而，注意力和思绪游走都是多成分的过程，它们之间的关系可能比之前认为的更为复杂。在本研究中，我们通过思维识别任务（TIT）（关于任务相关思维、任务相关干扰思维、外部干扰、与刺激无关及与任务无关的思维）来测试不同类型思维对注意力网络系统（ANT）不同成分（警觉、定向、执行）的干扰。结果显示，在ANT期间，个体主要受任务相关干扰思维影响，这些思维与外部干扰因素一起，显著降低了他们的表现准确性。然而，思绪游走（即与刺激无关及与任务无关的思维）并未显著干扰ANT中的准确性。在ANT中，未发现思维类型与警觉、定向或执行效应之间存在显著关系。虽然任务相关干扰思维和外部干扰似乎会损害注意力任务的表现，但思绪游走在ANT中仍与令人满意的表现相符。目前的结果证实了在研究思维干扰因素与注意力之间的关系时，区分“任务外”思维类型的重要性。
