Behavioral self-control procedures, composed of self-assessment, self-recording, self-determination and administration of reinforcement, were introduced into a regular third-grade classroom immediately after a baseline period. The procedures produced a small and unstable increase in the level of on-task behavior in eight of the nine subjects. After a second baseline period, a cueing procedure was introduced, using a chart specifying on-task behavior. This enabled within-lesson changes in on-task behavior to be posted clearly for the children. The cueing procedure combined with the self-control procedures produced a high and stable increase in on-task behavior in all subjects.

Techniques of behavioral self-control were employed in a class where a high level of on-task behavior had been established with externally administered reinforcement procedures. The behavioral self-control techniques maintained behavior at its ongoing high level both immediately following the externally administered reinforcement treatments and during follow-up treatments after five and seven weeks. Variability in on-task behavior was reduced during the behavioral self-control phases of the study.
