在一个联邦青少年教养所的场地上，在现有的垃圾中放置了一些不显眼的标记。囚犯自愿收集垃圾并将其存放在一个中心位置，在那里他们每发现一块有标记的垃圾就得到金钱或特权。一个多基线设计，在三个区域的垃圾计数显示，在基线的17天，22天和36天后，分别连续减少了55%，88%和71%。第四个领域作为基线对照，没有发现系统性变化。该程序的优点比以前设计的技术进行了讨论，并在其他领域的污染控制的建议应用。
Unobtrusively marked items of litter were placed among existing trash on the grounds of a federal youth correctional facility. Inmates voluntarily collected trash and deposited it at a central location, where they were given money or special privileges for each piece of marked litter found. A multiple-baseline design with litter counts in three areas revealed successive reductions of 55%, 88%, and 71% after 17, 22, and 36 days of baseline, respectively. A fourth area served as a baseline-only control, and revealed no systematic changes. Advantages of the procedure over previously devised techniques were discussed and applications in other areas of pollution control suggested.
