This study used event-related potentials to explore whether mind wandering (task-unrelated thought, or TUT) emerges through general problems in distraction, deficits of task-relevant processing (the executive-function view), or a general reduction in attention to external events regardless of their relevance (the decoupling hypothesis). Twenty-five participants performed a visual oddball task, in which they were required to differentiate between a rare target stimulus (to measure task-relevant…

An event related potential study of inhibitory and attentional control in Williams syndrome adults

Event-related potentials methodology is employed to disentangle the mechanisms related to inhibitory control in older adults with Williams syndrome, and deficits in the disengagement of attentional processes, and the regulation of monitoring processes required for successful inhibition are discussed.

Mind wandering and motor control: off-task thinking disrupts the online adjustment of behavior

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.

Distinct neural markers for intentional and unintentional task unrelated thought

Studies suggest that generating thought unrelated to the task in hand is accompanied by a reduction of attention to external task-relevant information. This observations led contemporary theory to

In Medio Stat Virtus: intermediate levels of mind wandering improve episodic memory encoding in a virtual environment

The results indicate that in a complex environment, the highest probability of actually remembering a scene would be when participants present a medium attentional level: neither distracted by inner thoughts nor too focused on the environment.

The more your mind wanders, the smaller your attentional blink: An individual differences study

It is suggested that mind wandering may be the behavioural outcome of an adaptive cognitive style intended to maximize the efficient processing of dynamic and temporally unpredictable events.

Going AWOL in the Brain: Mind Wandering Reduces Cortical Analysis of External Events

The data suggest that when trying to engage attention in a sustained manner, the mind will naturally ebb and flow in the depth of cognitive analysis it applies to events in the external environment.

Task unrelated thought whilst encoding information

Individual differences discriminate event-related potentials but not performance during response inhibition

It is concluded that the latencies of the N2 and P3 may be the critical indicators of active inhibitory processes for this task, suggesting that a pattern of sequential activation rather than altered activity level in key structures may mediate success on the task.

Slow Fluctuations in Attentional Control of Sensory Cortex

It is suggested that sensory gain control in cortex is yoked to the natural ebb and flow in how much attention the authors pay to the current task over time.

The neural bases of momentary lapses in attention

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.

Involuntary Attention and Distractibility as Evaluated with Event-Related Brain Potentials

Recent event-related brain potential studies of involuntary attention and distractibility in response to novelty and change in the acoustic environment show that the mismatch negativity, N1 and P3a ERP components elicited by deviant or novel sounds in an unattended sequence of repetitive stimuli index different processes along the course to involuntary attention switch to distracting stimuli.

The restless mind.

Evidence suggests that mind wandering shares many similarities with traditional notions of executive control, and can be seen as a goal-driven process, albeit one that is not directed toward the primary task.

Experience sampling during fMRI reveals default network and executive system contributions to mind wandering

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.
