• Hyperactivity in children has been attributed to underarousal, maturational lag, and both. Using event-related potentials (ERPs) and EEG spectra, we compared hyperactive children with age-matched normal controls. Neither underarousal nor maturational lag explained our findings, and we concluded that these explanations are now too simple to be useful. We found a number of differences in EEGs and ERPs between hyperactive subjects and controls. The best single measure was EEG power from 14 to 25 Hz, which was consistent with previous reports. Hyperactive children had lower beta power than normal controls.
