Effects of an Individual Contingency on Behaviorally Disordered Students in Physical Education
An A-B-A-B time series design was used to determine the effects of an individual contingency system in decreasing inappropriate and disruptive behavior of behaviorally disordered students in a physical education setting. Nine students (ages 8-13 years) participated in a 4-week physical education program in which response cost procedures (loss of free time) were systematically administered to individuals who did not follow class rules. Results indicated that during treatment and replication of treatment, the on-task behavior of all students improved from 44.0% to 69.1% and 38.1% to 71.6%, respectively. Older students appeared more responsive to treatment than younger students. Individually, three of five younger students (mean age 9.4 years) and all four older students (mean age 12.2 years) responded favorably to treatment. The study demonstrates that an individual contingency can be an effective behavioral strategy in modifying disruptive behavior which normally prevents these students from participation in physical education. In addition, younger as well as older students benefit from the approach, but not all individuals within this group responded favorably.
