Using Verbal and Visual Prompts to Control Littering in High Schools

Investigated the use of verbal and visual prompts to control litter behavior of students in 2 Western Australian high schools. 1,750 students participated in the study. Data were obtained from 2 areas in both schools: the cafeteria and the pathway leading from the cafeteria to the main teaching block. Verbal prompts in combination with visual prompts resulted in significant reductions in the rate of littering and were demonstrated to be more effective than verbal or visual prompts alone. Reductions in litter behavior were maintained following intervention.
