The Arnett Lab is currently enrolling 7-11 year-old children with and without ADHD. The goal of this study is to examine the brain mechanisms underlying rhythmic timing abilities in children with and without ADHD. We are using non-invasive electroencephalography (EEG) and neuropsychological testing to investigate auditory-perceptual and motor development in school-age children. Funding for the RACCOON Study is provided to Drs. Arnett and Pranjić by the GRAMMY Museum Foundation.
