Wagstaff, M. C. & Wilson, B. E. (1988). The evaluation of litter behavior modification in a river environment. Journal of Environmental Education, 20, 1, 39-44.

Evaluated the use of behavioral techniques in modifying the litter collection behavior of commercial rafting groups. 87 treatment Ss and 76 control Ss participated. A verbal appeal and role modeling comprised a treatment intended to prompt litter pickup. Designated pieces of trash were planted at the 1st night's campsite. Treatment groups left campsites cleaner, supporting the hypothesis that verbal appeal and role modeling by river guides can be effective litter control techniques.
