When attention wanders: how uncontrolled fluctuations in attention affect performance.
No matter how hard subjects concentrate on a task, their minds wander (Raichle et al., 2001; Buckner et al., 2008; Christoff et al., 2009; Killingsworth and Gilbert, 2010). Internal fluctuations cannot be measured behaviorally or from conventional neurophysiological measures, so their effects on performance have been difficult to study. Previously, we measured fluctuations in visual attention u...
متن کاملThe lights are on but no one's home: meta-awareness and the decoupling of attention when the mind wanders.
In a recent review, we suggested that an important aspect of mind-wandering is whether participants are aware that they are off task (Smallwood & Schooler, 2006). We tested this hypothesis by examining the information-processing correlates of mind wandering with and without awareness in a task requiring participants to encode words and detect targets with either a high or a low probability. Tar...

The focus seems to move relentlessly, shimmering and fidgeting no matter how hard we may try to concentrate on a thought, preserve an image, or otherwise freeze the instant. Not only does it seem quite impossibl...
متن کاملFor Whom the Mind Wanders, and When, Varies Across Laboratory and Daily-Life Settings.
Undergraduates ( N = 274) participated in a weeklong daily-life experience-sampling study of mind wandering after being assessed in the lab for executive-control abilities (working memory capacity; attention-restraint ability; attention-constraint ability; and propensity for task-unrelated thoughts, or TUTs) and personality traits. Eight times a day, electronic devices prompted subjects to repo...
متن کاملWhen the mind wanders: age-related differences between young and older adults.
Interest in mind wandering (MW) has grown in recent years, but few studies have assessed this phenomenon in older adults. The aim of this study was to assess age-related differences between young, young-old and old-old adults in MW using two versions of the sustained attention to response task (SART), one perceptual and one semantic. Different indicators were examined (i.e., reported MW episode...
