Two experiments evaluated the effect of commitment on paper recycling. Using an ABA design, Experiment I asked 24 individuals in a retirement home to sign a 4-week group commitment pledge to recycle paper. During this intervention, the subjects recycled 47% more paper than they had during baseline. They continued to recycle at this level during a 4-week follow-up period, when the group commitment was removed. Experiment 2 evaluated the relative effectiveness of group commitment, individual commitment, and token reinforcers on paper recycling in a college dormitory. The students in all three experimental conditions recycled from three to five times more paper than those in the control group during the 4-week intervention. However, in the 3-week follow-up period, when the treatments were removed, only the individually committed subjects continued to recycle significantly more paper than the controls.
