As anyone who has trained a horse knows, physical conditioning is only part of the equation — the mental side of an athlete's development can be just as critical to their career trajectory, if not more so. A recent virtual session of the Thoroughbred Aftercare Summit tackled questions surrounding learning theory and behavior in horses, and examined the way our understanding of equine learning can apply to retraining off-track Thoroughbreds (OTTBs).

Our academic understanding of the way horses learn doesn't always mesh with traditional training methods, according to Dr. Robin Foster, certified behavior consultant and research professor at the University of Puget Sound and Dr. Camie Heleski, equine lecturer at the University of Kentucky.

To understand the differences, it's important to know the basics of learning theory. Learning theory refers to the way an organism, from slugs to humans and anything in between, navigates its environment by creating associations between its behavior and its environment. Generally, different species are thought to have different capacities for learning and cognition based on academic research. On a basic level, an organism may learn from positive reinforcement, negative reinforcement, or punishment. Reinforcement, whether positive or negative, is designed to increase the frequency of a behavior, while punishment is designed to decrease the frequency of a behavior. The term positive reinforcement describes the addition of something the animal wants — in a horse's case, a treat or a scratch on the face or withers, as a reward for a desired response. Negative reinforcement refers to the removal of something the horse doesn't want.

“In the horse industry, we don't use positive reinforcement enough,” said Heleski. “Negative reinforcement is mainly what we use for traditional training. We squeeze the horse with our legs, applying pressure. The horse moves forward, we remove the pressure.”

Of those three choices, horses (and lots of other species) are shown to learn best through positive reinforcement. Punishment is commonly employed with horses, but isn't actually the most effective way to teach them.

“This is not only true with horses but it is perhaps especially true with horses — when horses do something that is unwanted, maybe it's unsafe, it's not a behavior we're looking for, it's annoying — it draws our attention,” said Foster. “I can't tell you how many people will say, 'I just want to stop that behavior.' It we want to decrease a behavior we don't want, we punish it. But there are better alternatives because punishment itself does not provide any alternative for the horse. It's really important to focus more on the behavior you want the horse to do ad make sure you reinforce that.”

It's easy to think punishment is effective, because it often generates a quick response, but Foster said it's rarely a permanent one. Because the horse hasn't been shown what the handler does want, it's likely the horse will repeat the undesired behavior eventually. This is especially problematic with Thoroughbreds, who Heleski and Foster agree are more sensitive to perceived threats and are therefore sensitive to punishment or reinforcement.

Heleski said she tends to encounter a bias against positive reinforcement in much of the equestrian world because many trainers are averse to giving horses frequent treats. The concern for many is the horse will come to expect food, and become mouthy or pushy in search of it. Most experts suggest handlers ignore pushy behavior and focus on rewards in specific instances where a horse is exhibiting desired behavior — keeping in mind that sometimes, the desired behavior is the absence of something, like kicking out or pawing in a grooming stall. Some horses are especially reactive to treats and will get excitable, searching for the food or trying to guess what their handler wants from them (which, at the start of positive reinforcement training, may be unclear to them). In those cases, Heleski suggests putting a gate or stall door between the horse and handler at first, or dispensing treats into a pan on the ground rather than feeding by hand.

If handlers are really concerned about “mugging” for treats, Heleski said research shows scratching on a horse's withers is a hugely impactful positive reinforcement. The attention, which mirrors mutual grooming, has been shown to decrease heart rate. Foals are also well known to enjoy scratches to their foreheads or the undersides of their necks.

One question Heleski and Foster are asked often is what to do about stereotypic behaviors like cribbing and weaving, which seem to be a focus for some horses no matter what type of reinforcement or punishment is used to stop them. Foster explained that although it may not feel this way, horses aren't doing these things to frustrate the humans around them.

“These repetitive behaviors that bother us — and they really bother people — they are very soothing to horses,” said Foster.

On a biochemical level, many of those behaviors have been shown to provide an enormous stress relief for the horse. It's a coping mechanism for anxiety about something around them. If the horse isn't doing significant harm to themselves, Foster suggested, it may be better to let these things ride. Otherwise, you're trying to take away a coping mechanism that could be very important to the horse, probably without providing alternate stress relief.

The good news for OTTB owners is not only that Thoroughbreds are known as a breed to be quick learners, but they also come off the track knowing a lot already. The racetrack routine includes lots of different stimuli that a horse wouldn't necessarily get in a riding barn.

“If I were to adopt a 3-year-old of another breed, most of the time they would not have had anywhere near the number of experiences that a 3-year-old Thoroughbred has had,” said Heleski. “I think that's a huge selling point to adopting these horses.”
