A research programme was undertaken to investigate the specific disabilities of hyperactive children and to evaluate the effectiveness of one of the stimulant drugs on the measures found to differentiate between hyperactives and normals. It is argued that a core group of symptoms involving inability to sustain attention and to control impulsivity can account for most of the deficits found in the hyperactive group. It also appears that the stimulants exert their main effect on these deficits. Correlational and factor analytic studies suggest that the same constellation of abilities underlies the behaviour of normal children in several areas of cognitive and social functioning.
