| Abstract: | In a 6-month follow-up study of 2 interventions with hyperactive boys, different patterns of improvement were observed for an intervention which focused on self-control and 1 which employed contingent social reinforcement. Of the 2 manipulations, self-control methods produced significantly stronger long-term benefits in terms of the child's increased perception of personal control over academic outcomes; social reinforcement, on the other hand, produced significantly stronger long-term benefits in terms of teacher ratings of hyperactivity or impulsivity (Conners Teacher Rating Scale). Both interventions produced stable changes in terms of decreased behavioral impulsivity as measured by qualitative error scores on the Porteus Mazes. |
