Cost and Effectiveness of Litter Removal Procedures in an Amusement Park
Casey, L. & Lloyd, M. (1977). Cost and effectiveness of litter removal procedures in an amusement park. Environment and Behavior, 9, 4, 535-546.
Evaluated a reinforcement procedure designed to facilitate litter removal in an amusement park. A constantly changing population of vacationing children of varying ages was offered complimentary tickets for amusement park rides contingent upon collection of bags of litter in the park. A cost/effect analysis showed that this particular reinforcement program for litter removal was approximately 21/2 times as effective at about the same cost as traditional salaried maintenance.
