The Hyperactive Child in Adolescence

The primary purpose of this research was to search for differences on a wide spectrum of cognitive, behavioral, and pyschophysiological measures between male adolescent psychiatric patients who were successfully treated for hyperactivity as younger boys, normal controls, and adolescent psychiatric patients who were not formerly hyperactive. A secondary purpose involved testing the hypothesis that time perception will significantly differentiate these three groups, which were matched for mean IQ levels. The patients who were not formerly hyperactive did more poorly on cognitive and behavioral tasks than did the controls and formerly hyperactive patients. Time perception significantly differentiated between controls and patients.
