A Wandering Mind Cannot Resolve Conflicts in Displayed Information

Human minds often wander around while performing a task. When the mind wanders, attention drifts away from task-relevant perceptual information, leading to deteriorated performance on the task at hand. The current study aims to examine how mind-wandering is associated with different aspects of attentional functions that are critical for perceptual processing of displayed information. Participants completed the Attention Network Task that assessed efficiencies of alerting, orienting, and executive functions of attention. During this task, participants reported their state of mind (focusing on the task or mind- wandering). The results showed that mind-wandering was particularly associated with impairments on executive function, which suggests that an ability to resolve conflicts in displayed information can be impaired when a mind wanders. Our findings suggest that, in work environment where mind-wandering is more likely to occur, tasks requiring conflict resolution in displayed information may be significantly impacted. Mechanisms of mind-wandering and implications in practical settings were discussed.
