SMART: Sensitivity models for animals in response to training.

The research presents a system called SMART that graphical models how training cues influence a horse’s behavior. It focuses on the impact of these cues on a horse’s propensity for left or right movement, stopping or going, and its likelihood to respond positively to certain stimulus strengths.

Overview of the SMART System

• The SMART system is a conceptual, three-dimensional model that maps out how horses respond to different training cues. These cues come from reins, the trainer’s legs, and seat.
• The system is designed specifically for ridden horses. Its purpose is to create a visual representation of a horse’s reactions to training, making it easier for trainers to understand and respond accordingly.

Assumptions of the SMART System

• The models assume that the trainer’s cues are bilaterally equivalent. This means that unless the trainer intends to signal a turn or a lateral movement, the cues given on each side of the horse will be the same.
• The degree to which ‘go’ signals result in straight, forward locomotion reflects the bilateral balance of the horse’s reactions. Essentially, a well-balanced response to ‘go’ signals should see the horse move straight forward.

Dimensions of the SMART System

• The Z-axis of the system represents the probability of a favorable response from the horse for a specific strength of stimulus. This score is then compared to competing stimuli from other sources. A Z value of 0 for a particular X (left versus right movement) and Y (stop versus ‘go’) coordinate indicates that the horse is not responding to the trainer’s stimulus as desired.
• The X-axis measures the horse’s left versus right movement in response to the trainer stimulus. This allows trainers to visually understand the impact of their commands on the horse’s directional movement.
• The Y-axis measures the horse’s tendencies to ‘stop’ or ‘go’ when exposed to differing stimulus strengths from the trainer. This helps trainers understand how their commands influence the horse’s movement behaviors.
