Horses are a Lot Smarter Than We Previously Thought, New Research Shows

A new study showed the animals performed better than expected in a complex reward-based game.

Researchers found that when denied treats for not following the rules of the game, the horses were able to instantly switch strategies to get more rewards.

It shows the animals have the ability to think and plan ahead - something previously considered to be beyond their capacity, scientists from Nottingham Trent University (NTU) said.

[...] Dr Carrie Ijichi, a senior lecturer in equine science at NTU, said: "Horses are not natural geniuses, they are thought of as mediocre, but this study shows they're not average and are, in fact, more cognitively advanced than we give them credit for."

To understand more, the researchers set 20 horses a task consisting of three stages.

In the first stage, the animals touched a piece of card with their nose in order to get a treat.

But things became more complicated when a light was introduced and horses were only allowed a snack if they touched the card while the light was switched off.

The team found that the horses kept blindly touching the card, regardless of whether the light was on or off, and were rewarded for correct responses.

In the final stage of the game, a penalty was put in place where touching the card when the "stop" light was on resulted in a 10-second time-out.

But instead of indiscriminately touching the card, the team found that the horses were engaging with the rules - only making a move at the right time in order to receive their treat.

The researchers said this suggests that rather than failing to grasp the rules of the game, the horses had understood it the whole time but had found a way to play in the second stage that did not require much attention.
