Study Details

Brief summary:

This project will study how fidgeting relates to cognitive and emotional functioning in adults with attention-deficit/hyperactivity disorder (ADHD). It will determine, in a laboratory setting, whether movement and access to a "fidget device" providing sensory and motor stimulation can improve cognitive and emotional regulation (including on physiological measures) in adult ADHD. The investigators will also acquire pilot data for machine learning analyses to be used in future, large scale studies to identify gestures and touch characteristics associated with improved cognitive and emotional regulation to see if the data can predict and subsequently develop recommendations to improve performance and emotional control in natural settings (e.g., home, office, college classroom) for adult ADHD.
