title: The use of stimulus control over littering in a natural setting.
abstract: A conventional litter receptacle (55-gallon drum) and a specially designated receptacle consisting of a 55-gallon drum adorned with a plywood "har" were alternated in two areas of a football stadium over a period of four games. A frequency count of several types of litter articles showed that more than twice as many items were deposited within the experimental container than the conventional one (an average of 52.5 and 21.5 items per game, respectively). The weight of litter deposited within each container showed a similar relationship. An average of 0.65 kg of litter per game were deposited within the conventional receptacle compared with an average of 1.3 kg per game for the experimental receptacle.
