This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing transcranial photobiomodulation (tPBM)—a treatment that uses near-infrared light delivered to the scalp—to see if it can improve attention, focus, and impulse control in adults. Some people naturally struggle with attention, and others have been diagnosed with ADHD. Researchers believe that activating a specific part of the brain with this light might help both groups pay attention better.
People with attention difficulties often feel their quality of life suffers because they struggle to focus or control impulses. While this treatment has shown promise for boosting brain function and mood in healthy adults, no one has carefully studied whether it actually helps improve attention in people with ADHD.

You'll come in for one visit where researchers will first ask you screening questions to understand your attention and focus. Then, you'll receive either the infrared light treatment or a placebo (where the device is placed on your scalp but the light is off) for 8 minutes—you won't know which one you're getting. After that, you'll complete a 14-minute computerized attention test that measures how well you can focus and respond to tasks on a screen.
