From Black Beauty to The Chronicles of Narnia, films and books have often shown the friendships that can develop between humans and horses. Lots of real-life stories have shown that horses seem to have a special understanding of humans. However, until a recent study, nobody knew if horses really recognized different human emotions.

A team of researchers set out to see what horses can understand. They used a test that is often used to see how much babies understand about the world around them.The team brought 28horses into a room, one by one. Each was shown a picture of a happy human and a picture of a sad human. At the same time,a recording of a happy or sad voice was played.The test showed that horses can recognize different emotions by looking at facial expressions and hearing the tone of people’s voices and matching the two up.When the voice didn’t match up with the picture, the horses seemed to be puzzled: they looked at the picture for longer, as if they knew that something wasn’t right. However, the researchers still don’t know if the horses actually understand what it is to be sad or happy.

Scientist Océane Liehrmann, from the University of Turku in Finland, worked on the study. She said,“You could imagine that they have a particular box in their mind labelled (贴标签)’human sadness’ containing the characteristics of both a sad face and a sad voice.”

It’s also thought that horses prefer to spend time around happy people because they spent longer looking at the pictures of happy people.The researchers now want to see if horses can recognize other negative human emotions.
