Yes, Horses ‘Figure Out’ Tasks from Watching Humans but Rarely Mimic Them

You put your right hand on,

You take your right hand off,

You put your right hand on… the handle,

And you turn it to the right….

You do the hokey pokey and you turn yourself around. That’s what (getting out of your barn) is all about!

Horses learn by watching people

Welcome to the social learning version of the Hokey Pokey. As many owners already know, horses can learn by watching what we do—especially when it comes to things we don’t want them to do, like opening doors…

Science, meanwhile, has recently confirmed it: yes, horses are capable of ‘interspecies social learning’ – learning how to perform tasks by watching people do them.

There’s at least one remaining question, though. How exactly are these animals learning from watching us? What’s the process, and what’s going through their minds? Is it all essentially one big Hokey Pokey, where they mimic what we do as best they can with their non-human body parts?

According to German researchers, no, that’s not really it.

Most horses don’t really seem to be trying to recreate the same maneouvers that we’re doing. Instead, observing us achieving a task—like opening a door latch—helps them realise that it’s possible to do it and it has something to do with the mechanisms we touched. The rest, they say, is up to their own problem-solving.

“The horses in our study mainly appeared to benefit from what we call ‘enhancement,’ said Konstanze Krueger.

“Enhancement is sort of like giving hints,” she explained. “You hint about where to find the clues, or what parts need to be manipulated, without step-by-step instructions. Essentially these horses were learning from the humans that a certain button needed to be pushed somehow, and they took it from there through trial and error.”

In other words, horses won’t necessarily copy a human’s exact movements or use equivalent parts of the body, Krueger said.

To test how horses learn from humans, Krueger and her fellow researchers designed social learning tests for horses at their own farms.

The horses were given access to a closed food box and, one meter apart, a button on a box on the ground that triggered an electric opening of the food box. About a fifth of the horses were left to try to figure out how to open the box on their own. The others were given the chance to watch a human push the button, activating the opening of the box.

Each horse’s own regular handler acted as a demonstrator, because horses are more likely to learn from individuals who are familiar to them, according to Krueger. The researchers randomly had the handlers perform one of four demonstrations for pushing the button: with the hand, with the forehead, with the forehand and head at the same time, and with the foot.

Altogether, 75% of the horses who watched a demonstrator ended up learning to open the box. (The researchers were sure the horses had “learned” when they were able to open it 20 times in a row.) That was more than double the success rate of the small group of horses that didn’t have a demonstrator, in which 31% eventually figured out how to open the box, Krueger said.

However, regardless of the kind of demonstration, the horses generally used their mouths—through nibbling, biting, licking, and pushing with the lip—to push the button, according to Krueger.

Some people might argue that this shows a reduced level of intelligence for the horse, since the horse didn’t ‘understand’ that he needed to copy the exact movements, Krueger said. However, it’s also possible that the very opposite is true—the horse understood what needed to be done and, through trial and error, adapted the situation to his own abilities or even preferences.

“You could certainly argue that it’s cleverer to observe a person and then make up your mind how you would do it yourself, and come up with your own technique,” she said.

Still, there was individual variation, she added, explaining that some horses did attempt the same technique as their demonstrators. That was especially true, she said, for the use of the foot.

“About half the horses seeing the foot demonstration used their hoof to push the button,” Krueger said. “Most of those used the hoof consistently, every time, but a couple of them alternated between the hoof and the head (mouth).” The horses in the foot demonstration group used their hooves significantly more than the horses in the head and hand demonstration groups, she added.

Whether this means horses assimilate human feet to their own feet is yet to be determined, according to Krueger. “Of course I cannot look into the horse’s head, but yes, some appear to observe closely and reason that they have to use a hoof when humans use their foot,” she said.

In that respect, in the “equine social learning hokey pokey” might do better to start, rather than the arms, with the feet.

Professor Konstanze Krueger from the equine economics department of University of Nürtingen Geislingen, was lead author in an earlier study on the ability of horses to open door and gate mechanisms.

The full research team also comprised Kira Bernauer and Hanna Kollross from Nürtingen-Geislingen University, Auriela Schuetz from Georg-August-University Goettingen, and Kate Farmer from St Andrews University in Scotland.
