Now recruiting!

We are actively recruiting 9- to 11-year-old children without ADHD and 2.5- to 4-year-old children with OR without a family member who has ADHD to participate our studies.

If you would like to learn more, please email or call 617-919-7771.



The Arnett Lab is currently enrolling 7- to 11-year-old participants for the RHINO ADHD Study (RHINO = Research on Heterogeneity In NeurOdevelopmental disorders and ADHD). The goal of this study is to characterize biomarkers of individual differences among school-age children with ADHD. Our methods include electroencephalography (EEG), in which we measure brain activity in a comfortable and fun way for the children, as well as neuropsychological testing and an interview. The RHINO ADHD study is funded for three years by the National Institute of Mental Health (NIMH).


The Arnett Lab is currently enrolling 2.5- to 4-year-old participants for the RHINO-Mites Study. The goal of this study is to identify brain markers associated with familial risk for ADHD and ADHD outcomes. As with the RHINO study, methods include electroencephalography (EEG), in which we measure brain activity in a comfortable and fun way for the children, as well as neuropsychological testing and an interview. The RHINO-Mites study is funded for three years by the National Institute of Mental Health (NIMH).

Museum of Science study

This past summer we partnered with the Living Laboratory at the Museum of Science for our AEROBIC Study. In this study, individuals 5 and older were randomly assigned to play either an “exercise” game or a “relaxation” game before completing a short test of attention and inhibitory control. The goal of this study was to help us understand how exercise and relaxation can impact a person’s ability to pay attention and regulate impulses. We hope that our research will continue to contribute to development and improvement of treatments for children with ADHD.


The Re-ACTIVE study was conducted at the University of Washington Center on Human Development and Disability. This study involved repeat EEG testing of 60 school-age children who successfully completed the ACTIVE Study at UW. The research goal is to evaluate stability of neurophysiological biomarkers in children with ADHD. This study is funded by the Klingenstein Third Generation Foundation (KTGF).

READY Study (Relations of EEG and methylphenidate response in Attention Deficit hyperactivitY disorder)

The READY Study was run by Tara Rutter, MS, and constituted her doctoral dissertation in psychology at Seattle Pacific University. READY was an extension of the ACTIVE study and examined EEG correlates of stimulant medication response. Previous ACTIVE study participants who have ever taken methylphenidate were eligible for this study. The goal of this study was to examine potential biomarkers of methylphenidate response among children. The investigation involved a short online questionnaire about your child’s medication history and also included a short parent phone interview.

ACTIVE Study (ADHD and Cognition: Tackling Individual Variability with EEG)

This study was supported by a NIMH K99 research grant awarded to Dr. Arnett. The goal of the research was to identify subtypes of ADHD that are defined by common patterns of activity in the brain. The study involved electroencephalography (EEG), which is a non-invasive way of measuring electrical activity in the brain. Children with ADHD show atypical EEG responses to visual and auditory information, as well as atypical EEG patterns when completing a task that requires attention.
