Converging evidence from neuroscience suggests that our attention to the outside world waxes and wanes over time. We examined whether these periods of mind wandering are associated with reduced cortical analysis of the external environment. Participants performed a sustained attention to response task in which they responded to frequent nontargets (digits 09) and withheld responses for infrequent targets (the letter X). Mind wandering was defined both behaviorally, indicated by a failure to… Expand
The Decoupled Mind: Mind-wandering Disrupts Cortical Phase-locking to Perceptual Events
TLDR
It is document that the attenuation of perceptual processing that occurs during task-unrelated thought is associated with a reduction in the temporal fidelity with which the brain responds to a stimulus and suggest that increased neural processing may be required to recouple attention to a task. Expand
Mind wandering and motor control: off-task thinking disrupts the online adjustment of behavior
TLDR
It is found that the sensitivity of behavior and the P3 ERP component to feedback signals were significantly reduced just prior to mind wandering vs. on-task attentional reports, and decreases in the error-related negativity elicited by feedback signals (fERN), a direct measure of behavioral feedback assessment in cortex. Expand
Mind Wandering and the Adaptive Control of Attentional Resources
TLDR
The findings suggest that, although some selective attentional processes may be subject to down-regulation during mind wandering, the authors may adaptively compensate for these neurocognitively decoupled states by maintaining automatic deviance–detection functions. Expand
Dissociation of Subjectively Reported and Behaviorally Indexed Mind Wandering by EEG Rhythmic Activity
TLDR
Subjectively reported mind wandering within the gamma band is found to be characterized by increased activation in bilateral frontal cortices, supplemental motor area, paracentral cortex and right inferior temporal cortex in comparison to behaviorally indexed mind wandering. Expand
Wandering minds and wavering rhythms: linking mind wandering and behavioral variability.
TLDR
Responsibility variability during the 5 trials preceding probe-caught reports of mind wandering (tuned-out and zoned-out mind wandering) is significantly greater than during the5 trials preceding reports of on-task performance, suggesting that, at least in some tasks, behavioral variability is an online marker of mind wander.

Attenuation of Deep Semantic Processing during Mind Wandering: An ERP study
While much research shows that early sensory and attentional processing is affected by mind wandering, the effect of mind wandering on deep (i.e., semantic) processing is relatively unexplored. ToExpand
Attenuation of deep semantic processing during mind wandering: an event-related potential study
TLDR
The results support previous findings of sensory attenuation during mind wandering, and extend them to a long-duration slow wave by suggesting that the deeper and more sustained levels of processing are also disrupted. Expand
Mind-wandering Is Accompanied by Both Local Sleep and Enhanced Processes of Spatial Attention Allocation
TLDR
It is suggested that Mind-wandering occurs during phases of LS with processes of attentional target selection being upregulated, potentially to compensate for the mental distraction during MW. Expand
Detection of mind wandering using EEG: Within and across individuals
TLDR
This study is the first to demonstrate that machine learning models can generalize to “never-seen-before” individuals using electrophysiological measures, highlighting their potential for real-time prediction of covert attention states. Expand
Lost in thoughts: Neural markers of low alertness during mind wandering
TLDR
To the knowledge, this experiment is one of the first neuro-imaging studies that relies purely on subjects' introspective judgment, and shows that such judgment may be used to contrast different brain activity patterns. Expand

Experience sampling during fMRI reveals default network and executive system contributions to mind wandering
TLDR
An fMRI study that used experience sampling to provide an online measure of mind wandering during a concurrent task revealed a number of crucial aspects of the neural recruitment associated with mind wandering, highlighting the value of combining subjective self-reports with online measures of brain function for advancing the understanding of the neurophenomenology of subjective experience.

The lights are on but no one’s home: Meta-awareness and the decoupling of attention when the mind wanders
TLDR
The results are consistent with the notion that mind wandering involves a state of decoupled attention and emphasizes the importance of meta-awareness of off-task episodes in determining the consequences of these mental states. Expand

The findings support the suspension of internal cognitive processing as one mechanism fortask-unrelated thought (TUT) frequency using an auditory target detection task with seven levels of task difficulty. Expand
Mind-wandering and dysphoria
Mind-wandering shares a number of important similarities with thinking in depression. This experiment examines whether mind-wandering provides a useful marker of cognition in dysphoria during a wordExpand
The neural bases of momentary lapses in attention
TLDR
It is determined that attentional lapses begin with reduced prestimulus activity in anterior cingulate and right prefrontal regions involved in controlling attention, and increased stimulus-evoked activity in the right inferior frontal gyrus and the right temporal-parietal junction predicted better performance on the next trial. Expand
Subjective experience and the attentional lapse: Task engagement and disengagement during sustained attention
TLDR
The results suggest the authors can dissociate between two components of subjective experience during sustained attention: task unrelated thought which corresponds to an absent minded disengagement from the task and a pre-occupation with one's task performance that seems to be best conceptualised as a strategic attempt to deploy attentional resources in response to a perception of environmental demands which exceed ones ability to perform the task.

Tracking the train of thought from the laboratory into everyday life: An experience-sampling study of mind wandering across controlled and ecological contexts
TLDR
The propensity to mind wander appears to be a stable cognitive characteristic and seems to predict performance difficulties in daily life, just as it does in the laboratory. Expand
Cortical networks for working memory and executive functions sustain the conscious resting state in man
TLDR
The results suggest that brain activity during conscious REST is sustained by a large scale network of heteromodal associative parietal and frontal cortical areas, that can be further hierarchically organized in an episodic working memory parieto-frontal network, driven in part by emotions. Expand
The absent mind: further investigations of sustained attention to response
TLDR
Three further studies are presented which support the claim that performance is crucially determined by the duration of time over which attention must be maintained on one's own actions that this demand underpins the task's relationship to everyday attentional lapses. Expand

TLDR
TUIT likelihood was shown to be reliably measured over a wide range of vigilance tasks, to have high short-term and long-term test-retest reliability, and to be sensitive to information processing demands, and this method was offered as a reliable approach to quantification of such mental states as obsessions and drug craving and addiction.
