Study: Horses read, remember human faces

"In a series of experiments, researchers at the universities of Sussex and Portsmouth showed domestic horses photographs of humans with either a happy or angry expression on their faces. Later, the horses were introduced to the people they saw in the photographs, this time with neutral expressions."

"Researchers watched the eye movements of horses as they met the photograph subjects in real life. The horses perceived those who had been photographed with an angry face as more threatening."

"Previous research showed horses tend to focus on negative or threatening objects and events with their left eye, as the right hemisphere of their brain is tasked with assessing risk. In the new experiment, researchers found horses stared at subjects who had been photographed with an angry expression using their left eye."

""What we've found is that horses can not only read human facial expressions but they can also remember a person's previous emotional state when they meet them later that day -- and, crucially, that they adapt their behaviour accordingly," Karen McComb, a professor at the University of Sussex, said in a news release. "Essentially horses have a memory for emotion.""
