Perceptual-Speed Deficit in Reading-Disability Children.
In Study I, reading disability children were tested on perceptual encoding speed with a visual reaction-time task requiring same-different judgements. Performance of disabled children deteriorated as testing progressed, and recovered after a rest. In Study II, the poor readers of Study I were rated by their teachers on a 15-item inventory of abnormal motor behavior. Reaction time from initial trials of the test given in Study I was significantly correlated with the motor coordination factor on the inventory. In Study III, hyperactive boys taking methylphenidate medication and hyperactive boys whose medication was temporarily discontinued were tested. Reaction time on early trials was not significantly different for boys in the on-medication and off-medication groups. As testing progressed, reaction times of normal boys and boys taking medication remained fairly stable, while the performance of hyperactive boys not taking medication declined. (Author/CB)
