Fluctuating Minds: Spontaneous Psychophysical Variability during Mind-Wandering
Mind-wandering is the occasional distraction we experience while performing a cognitive task. It arises without any external precedent, varies over time, and interferes with the processing of sensory information. Here, we asked whether the transition from the on-task state to mind-wandering is a gradual process or an abrupt event. We developed a new experimental approach, based on the continuou...
متن کاملWandering minds: the default network and stimulus-independent thought.
Despite evidence pointing to a ubiquitous tendency of human minds to wander, little is known about the neural operations that support this core component of human cognition. Using both thought sampling and brain imaging, the current investigation demonstrated that mind-wandering is associated with activity in a default network of cortical regions that are active when the brain is "at rest." In ...
متن کاملThe role of the default mode network in component processes underlying the wandering mind
Experiences such as mind-wandering illustrate that cognition is not always tethered to events in the here-and-now. Although converging evidence emphasises the default mode network (DMN) in mind-wandering, its precise contribution remains unclear. The DMN comprises cortical regions that are maximally distant from primary sensory and motor cortex, a topological location that may support the stimu...
متن کاملLinking brain networks and behavioral variability to different types of mind-wandering.
Research focusing on mind-wandering (MW) has consistently shown that this mental state is accompanied by variable, error-prone behavior and increased activity within the default mode network (DMN) and the frontoparietal control network (FPN) (1–6). Given that the DMN has been implicated in internal mentation such as future planning or self-referential processing, whereas the FPN has been linked...
متن کاملMind-wandering and alterations to default mode network connectivity when listening to naturalistic versus artificial sounds
Naturalistic environments have been demonstrated to promote relaxation and wellbeing. We assess opposing theoretical accounts for these effects through investigation of autonomic arousal and alterations of activation and functional connectivity within the default mode network (DMN) of the brain while participants listened to sounds from artificial and natural environments. We found no evidence ...
