HighlightsA novel Go/No-go task points to a critical role for the IPS in response inhibition.IPS engagement in response inhibition is scaled back with ADHD symptom severity.Fronto-parietal connectivity increases when response inhibition is challenging.Connectivity modulation is also scaled back with ADHD symptom severity.
Objective: The present study evaluated the near (attention) and far (reading, ADHD symptoms, learning, and quality of life) transfer effects of a Computerized Progressive Attention Training (CPAT) versus Mindfulness Based Stress Reduction (MBSR) practice among adults with ADHD compared to a passive group. Method: Fifty-four adults participated in a non-fully randomized controlled trial. Participants in the intervention groups completed eight 2-hr weekly training sessions. Outcomes were assessed before, immediately after, and 4 months post-intervention, using objective tools: attention tests, eye-tracker, and subjective questionnaires. Results: Both interventions showed near-transfer to various attention functions. The CPAT produced far-transfer effects to reading, ADHD symptoms, and learning while the MBSR improved the self-perceived quality of life. At follow-up, all improvements except for ADHD symptoms were preserved in the CPAT group. The MBSR group showed mixed preservations. Conclusion: Both interventions have beneficial effects, however only the CPAT group exhibited improvements compared to the passive group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
