Mind wandering refers to a cognitive state in which an individual's attention shifts away from the task at hand and towards internal thoughts, memories, or fantasies unrelated to the present moment. This phenomenon is characterized by a lack of focused attention on external stimuli, and can occur spontaneously or be triggered by external cues. Research in this area explores the underlying mechanisms of mind wandering, its effects on cognitive processes and performance, and potential implications for mental health and well-being. Studies have shown that mind wandering is a common occurrence in everyday life, and that it can have both positive and negative consequences depending on the context and individual differences.
