The Mind Wanders

Escaping the here and now: future thinking as self projection during the mind wandering state

One observation from the last decade in both cognitive science and neuroscience is that prospection (the ability to think about the future) is important for humans because it allows the mind to prepare for events that may occur in the future. While this has largely been studied in explicit goal directed future thinking in the laboratory, in the last few months studies have begun to explore how such prospection operates during mind wandering; at the heart of the capacity to think about the future is the capacity for self or autobiographical memory. In one study published in a journal called Acta Psychologia, Stawarcyzk and colleagues demonstrated that Belgian participants tend to think more about the future during mind wandering if they were primed with a list of their personal goals prior to performing a simple task. In a similar vein, in collaboration with colleagues at the University of Aberdeen in Scotland, we demonstrated that this prospective bias arises because of the saliency of self referent information. In our studies (published in a journal called Consciousness and Cognition) participants were more likely to think about their personal futures during mind wandering (rather than past) if they were asked to rate as set of adjectives applied to themselves, rather than to either their best friend or the current UK prime minister or to a control group. In a second study, participants who engaged in the most future thinking during mind wandering showed the strongest memory for self rated adjectives. Together these two different studies demonstrate that autobiographical memory is at the heart of the capacity to mentally escape the here and now and engage in future thinking during the mind wandering state.

Absorbed in Thought NOT Simply Distracted

A couple of weeks ago in the journal Psychological Science, collaborators of mine from Nothumbria University published a study that looked at the reason why mind-wandering is associated with reduced processing of task relevant information. Using, EEG we measured the cortical response to events in a task. In this experiment we were especially interested in the brains response to distractor stimuli, because we wanted to assess whether people who mind wander are easily distracted. Our study showed the people who reported the most off task thoughts tended to show the smallest response to both the targets in the task and to the distracters. Thus while mind-wandering is associated with poor performance on task, this is independent of a process of external distraction. This result is important because it shows that the experience of mind wandering is not simply a state of poor attentional control, because the people who did the most mind wandering were also able to ignore the distracters in a sustained attention task. Rather than simply being a state of distraction, this study suggests that one reason why the mind neglects external information is because when it daydreams, the brain needs to filter out perceptual information, so as to allow it to concentrate on an internal train of thought. Failing to attend to perceptual information during idle moments is probably one important reason why we are able to concentrate on other more important personal goals, such as what to have on a dinner date or where to go on vacation. Rather than being a problem, being absent from the here and now when the conditions allow, may actually facilitate focus on the other problems that occupy our daily lives.

Imprisoned by the past: unhappy moods wander to their past

This week the journal Cognition and Emotion published a study by my colleague Rory O’Connor (Stirling University) and myself exploring the relationship between different mood states and the temporal focus that mind wandering tasks. The results suggested that being in a negative mood led people to mind wander to events in the past. This bias was especially pronounced in people with depression.

The current issue of PLOS One includes a recent paper by myself and my co-authors from UCSB which demonstrates that situations under which mind wandering is likely to occur are associated with increases in pupil diameter (see http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0018298). These changes are distinct from the changes that take place when the mind processes external information. This study suggests that pupilometry maybe a useful covert marker for internal focus and provides further evidence that internally maintained thoughts (such as mind wandering or daydreaming) are often associated with a state of increased arousal (such as strong emotion or important personal concerns).

Unhappy wanderings: further evidence of a link between mind-wandering and negative affect

Once again, mind-wandering has made headlines. A study by Killingsworth and Gilbert published in the journal Science has shown that one important consequence of mind-wandering is that when it happens people are usually unhappy. This study complements previous studies that have shown links with chronic low mood and experimentally induced mood in the lab (see the section on mood in Experimental Articles for examples). While conclusions about whether mind-wandering causes low mood or vice versa remain an open question, the study does underline how mind-wandering is strongly linked to states of negative affect.
