Reducing pawing in horses using positive reinforcement.

This research aimed to explore the impact of positive reinforcement (specifically, a method called differential reinforcement of other behavior (DRO)), in reducing unwanted pawing behavior in horses. The findings suggest that DRO was effective in lowering such behavior, though individual variations in response and the efficacy of reinforcement were noted.

About the Study

• The research was conducted aiming to find alternatives to the ‘aversive control’, which is frequently used to manage undesirable behaviors in horses but can lead to unintended negative implications, including the potential abuse of the animal. The researchers explored the use of positive reinforcement, specifically DRO (Differential Reinforcement of Other behavior), to mitigate undesirable behaviors in horses with fewer negative consequences.

Methodology

• The study conducted used DRO schedules, a form of positive reinforcement where desired behavior is reinforced, thus aiming to reduce the frequency of the undesirable behavior. In this case, the focus was on reducing pawing, a common undesirable behavior in horses.
• The research was carried out using a ‘multiple baseline design’ to track the behaviors of three horses before, during, and after the implementation of DRO schedules.

Findings

• The study showed that the implementation of DRO schedules was effectively able to reduce the pawing behavior in horses. This result provides probable support for the use of positive reinforcement methods over aversive control, as it appeared to lead to a positive behavior change with less negative impact.
• However, it was also found that there were individual differences in how the horses responded to the DRO schedules and the efficacy of the reinforcement. The researchers indicate that these factors could be crucial if DRO or similar positive reinforcement techniques are to be used practically for behavior modification in horses.

Implications

• This research provides valuable insights for the fine-tuning of behavior modification strategies for horses, especially in favor of positive reinforcement methods like DRO.
• Understanding the factors like individual differences in response to reinforcement could lead to more informed and effective approaches to managing undesirable behaviors in horses.
• The findings can potentially impact broader animal behavior management practices and reduce the reliance on negative control methods.
