The effectiveness of task clarification, positive reinforcement and corrective feedback in changing courtesy among police staff

Performance by the participants improved after their task was clarified. The results indicated that the need to define responsibilities is needed to maximize efficiency. On the other hand, feedback intervention and positive reinforcement suffered setbacks due to several factors, one of which is the ineffectiveness of positive reinforcement from outsiders. Participants value more their supervisor's feedback. It was concluded that it would be harder to implement performance improvements in the police force due to the varying situations they are subjected to.
