[Formula: see text] Unraveling the relationship between executive function and mind wandering in childhood ADHD.

Attention Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent neurodevelopmental disorders in children. According to developmental literature findings, there is a link between executive function (EF) and ADHD. Although EF deficits vary across ADHD presentations in children, working memory capacity is commonly associated with attention impairments. Notably, deficits in working memory capacity are also observed in frequent mind wandering reports for typically developing children. Mind wandering is shifting attention away from a current task to an unrelated thought. To explore the relationship between EF and mind wandering in children with ADHD ( = 47) and further compare our current sample to a typically developing (control) group from a previous study ( = 47), all participants completed three EF-related tasks. They concurrently reported if they were on task or mind wandering. Our results indicate better short-term memory capacity predicted lower mind wandering frequency in children who reported high levels of ADHD symptoms. Similar trends were observed for working memory capacity and ADHD symptomatology. Children with ADHD also reported more overall and unintentional mind wandering on questionnaires compared to children without ADHD. However, the relationship between EF and mind wandering did not differ between these groups. The current study suggests memory-related cognitive abilities may inform our understanding and management of mind wandering in children, driving the development of interventions targeting attention regulation.
