Fidgeting and Attentional and Emotional Regulation in ADHD

Fidgeting is a highly common behavior, with excessive fidgeting associated with attention-deficit/hyperactivity disorder (ADHD). Studies from the investigator's laboratory and colleagues suggest physical movement can enhance cognitive performance in children with ADHD. Hyper-sensorimotor behavior may be related to impaired regulation of arousal in the noradrenergic and dopaminergic systems. This project will assess if frequency and characteristics of sensorimotor behavior relates to cognitive and emotional response in adults with ADHD, in a fine-grained manner, unlike other studies. The investigators will test if intrinsic fidgeting (Aim 1) and access to a specially designed fidget device (Aim 2) modulates behavioral and physiological response in cognitively and emotionally-demanding contexts. The hype of the commercially available fidget devices, its competitors and fidget spinners suggest it might, but there is no systematic evidence to inform consumers, a gap, the investigators aim to fill.
