Techniques of behavioral self-control were employed in a class where a high level of ontask 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.Classroom behavior that is independent of teacher control or control by any agent external to the learner is a commonly acknowledged primary goal of education. A practical means of attaining this goal lies in the development of procedures of behavioral self-control in classroom settings.A conceptual base for the analysis of selfcontrol is offered below in terms of four behavioral components. Bandura and Perloff (1967) outlined a similar conceptual system. The components are:(1) self-assessment-the individual may examine his own behavior and decide whether or not he has performed a specific behavior or class of behaviors.( 2) Various recent studies have employed one or more, but not all, of these components. For example, the self-monitoring procedures of McFall (1970) and Thomas, Abrams, and Johnson (1971) incorporated both self-recording and self-assessment. Usually, the behavioral self-control components are combined with experimenter imposed restrictions (Kanfer, Bradley, and Marston, 1962;Kanfer and Duerfeldt, 1967).While there is a considerable body of literature dealing with the components of behavioral self-control (Kanfer and Marston, 1963;Marston, 1964;Goldiamond, 1965;Bandura and Whalen, 1966;Bandura, Grusec, and Menlove, 1967;Masters, 1968;Chapman, Smith, and Layden, 1971) only a few studies have been conducted in classroom settings. Lovitt and Curtiss (1969) found that with a 12-yr-old student, higher rates of responding occurred when the student arranged the contingency requirements than when the teacher specified them. The contingency manager, not the reinforce-105 1973, 63, [105][106][107][108][109][110][111][112][113] NUMBER 1 (SPRING 1973)
