Abstract. We have evolved artificial neural networks to control the wandering behavior of small robots. The task was to touch as many squares in a grid as possible during a fixed period of time. A number of the simulated robots were embodied in small Lego (Trademark) robot, controlled by a Motorola (Trademark) 6811 processor; and their performance was compared to the simulations. We observed th...

One mechanism that has been hypothesized to contribute to older adults' changes in cognitive performance is goal neglect or impairment in maintaining task set across time. Mind-wandering and task-unrelated thought may underlie these potential age-related changes. The present study investigated age-related changes in mind-wandering in three different versions of the Sustained Attention to Respon...

Mind wandering has been investigated in a variety of sustained attention tasks. In the present research, we investigated the role of mind wandering while listening to familiar or unfamiliar musical excerpts, and its effects on linguistic processing. Participants performed a lexical congruity task involving judging the semantic relatedness of a list of word pairs while listening to familiar clas...

We present a computational cognitive model of mind wandering, an important cognitive phenomenon whose mechanisms are involved in insight, problem-solving, and creativity. The model posits that mind wandering begins when one is not engaged in goal-oriented cognition, whether when between tasks or when in the middle of a task but not actively thinking about one’s goal. At such times, the model th...

When we get distracted, we may engage in mind-wandering, or task-unrelated thinking, which impairs performance on cognitive tasks. Yet, we do not have cognitive models that make this process explicit. On the basis of both recent experiments that have started to investigate mind-wandering and introspective knowledge from for example meditators, we built a process model of distraction in the form...

Unintentional lapses of attention, or mind wandering, are ubiquitous and detrimental during learning. Hence, automated methods that detect and combat mind wandering might be beneficial to learning. As an initial step in this direction, we propose to detect mind wandering by monitoring physiological measures of skin conductance and skin temperature. We conducted a study in which student’s physio...

Recent research has shown that mind wandering recruits executive resources away from the external task towards inner thoughts. No studies however have determined whether executive functions are drawn away in a unitary manner during mind wandering episodes, or whether there is variation in specific functions impacted. Accordingly, we examined whether mind wandering differentially modulates three...

People’s minds sometimes wander from their ongoing activities. Although these experiences can be pleasant and useful, they are often unintentional and precipitate mistakes. This article adopts an individual-differences perspective in considering unwanted mind-wandering as indicating both a momentary failure of, and an enduring deficiency in, executive-control functions. We describe research tha...
