Vigilance and mind wandering

Abstract

Mind wandering is a pervasive feature of experience. But why does the mind wriggle about rather than stay focused? The answer depends on understanding mind wandering as task‐unrelated thought. Despite being the standard view of mind wandering in cognitive psychology, there has been no systematic elaboration of the task‐unrelated thought view of mind wandering. I argue for the task‐unrelated thought view by showing how mind wandering reflects a distinctive form of non‐vigilant thinking. This argument defuses several objections to the task‐unrelated thought view. The account of mind wandering defended here is also compatible with a naturalistic account of subjectivity.
