Effectiveness of three contingency-nonspecific stimuli on bathroom graffiti prevention in a college setting
1University of Connecticut, USA.
Abstract:
An A-B-A design was adopted to test the effectiveness of different types of contingency-nonspecific stimuli in the prevention of bathroom graffiti in a college setting. The three stimuli examined in this study have been frequently used to prevent bathroom graffiti in South Korea and they were: (a) "Please do not write, draw, or mark on these walls;" (b) a mirror; and (c) "Courteous people keep public places clean." No graffiti was observed when the first and second stimuli were presented. In contrast, a notable increase in bathroom graffiti was observed when the third sign was presented. The results suggest that a contingency non-specific stimuli posting intervention can be effective in the prevention of bathroom graffiti only when appropriate stimuli are used. The practical implications, including cost-effectiveness, are discussed.
