| Abstract: | Two studies compared the attitudinal and behavioral effects of certain rewards and lotteries. In a laboratory experimental study, lotteries produced significantly more attitude change than cash payments. The greatest attitude change occurred among lottery winners. In a quasi-experimental field study, subjects rewarded with lottery tickets recycled glass and newspaper more frequently than subjects receiving other individual or group rewards. Attitude change was not affected by the type of reward Implications for the design of incentive programs to increase prosocial behavior are discussed |
