성인 인지적 이탈 증후군 집단과 ADHD 집단의 의도적, 비의도적 마음 방황 비교 연구 = A Comparative Study of Intentional and Unintentional Mind Wandering in Adults with Cognitive Disengagement Syndrome and ADHD

다국어 초록 (Multilingual Abstract)

Mind wandering is defined as a shift from task-related thoughts and events in the ongoing task or external environment to self-generated thoughts and feelings unrelated to the task. Research indicates that the intentional mind wandering decreases, while the unintentional mind wandering increases with higher task difficulty. Mind wandering can be measured through self-report measures and experience sampling during the performance of the Sustained Attention to Response Task(SART). Attention Deficit Hyperactivity Disorder(ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, impulsivity, and hyperactivity. Cognitive Disengagement Syndrome(CDS) is a cluster of symptoms involving excessive daydreaming, mental confusion, slow behavior, and thinking. While self-reported unintentional mind wandering was related to ADHD, experimental studies reveal, that ADHD is more strongly associated with unintentional mind wandering than with intentional mind wandering. CDS was associated with mind wandering, and ADHD was reported to be related to external distractibility.
The aim of this study is to translate and validate the Mind Wandering Questionnaire(MWQ; Mrazek et al., 2013), distinguish intentional and unintentional mind wandering, compare ADHD, CDS, and control groups, and explore the characteristics of mind wandering in ADHD and CDS. Participants comprised 18 adults with ADHD, 22 adults with CDS, and 25 in the control group. Mind wandering was assessed using MWQ and experience sampling during the performance of the SART. The SART task, varying in difficulty conditions, was conducted in a Go/No-Go format.
The results showed that the ADHD group had a higher overall frequency of mind wandering based on the self-report, i.e MWQ, and the overall mind wandering rate during the SART was higher. In contrast, the CDS group reported a similarly high overall frequency of mind wandering in everyday life as ADHD, with no difference in the overall mind wandering rate between the CDS group and the control group in the laboratory task. These results suggest that adults with ADHD exhibit problems with controlled processing in both everyday life and laboratory task. Conversely, adults with CDS only show issues with controlled processing in everyday life.
