Fidgeting and Attentional and Emotional Regulation in ADHD
What this study is about
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.
View original scientific description
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
