A good-behavior game was implemented in a fifth-grade reading class consisting of two groups of 14 students each. After the presentation of the game, reversal and component analysis phases were instituted. Game components included rules, lights (response feedback), and group consequences of extra recess and extra free time. Student observers recorded the dependent variables which included talking-out, disruptive, and out-of-seat behaviors. The results show that the game reduced the dependent measures from their baseline rate by almost 99% for one group and 97% for the other. The component analysis revealed that after association in the game, the stimulus components of rules and lights were effective in reducing the dependent behaviors.
