The effects of individual and group contingencies on reading performance of special education students

The effects of individual and group contingencies on the reading performance of 10 special education students were examined in a counterbalanced multiple-baseline design with experimental manipulations introduced at random. During the Baseline condition no consequences for accuracy in programmed reading were in effect. With the Group Contingency, pupils earned points based on accuracy and exchanged them for activity backup reinforcers based on the average performance of the group. During the Individual Contingency arrangement, the same point totals were awarded by yoking pupils to the group behavioral criteria. The results indicated superior accuracy (from 2 to 25%) with the Group Contingency by all 10 pupils. Student preferences as to the two contingency arrangements indicated a slight preference for the Group Contingency phase. A lack of negative peer comments was noted over the duration of the experiment. Results were also discussed in terms of ease of implementation of the group contingencies within an ongoing token economy in a classroom setting. Tentative reasons for the differing results of the present study and others were presented.
