Horses can recognize different facial expressions and distinguish human emotions such as joy and anger, a study revealed today at England’s University of Sussex.
the experiment, the results published in the journal “Biology Letters”, the researchers analyzed the reaction of 28 horses after presenting pictures with the face of a man who showed both positive and negative feelings.
the co-director of research Amy Smith, explained that “the main result was the discovery that looked (angry faces) through his left eye.”
Like all mammalian brains, the information received by the ocular route is transmitted to the right hemisphere, which is responsible for processing the “negative incentives”.
the scientists also found that the heart rate of these animals was increased significantly when left exposed to faces of anger or anger .
We also found that other species such as dogs, negative actions contemplated by the left eye.
as Smith said, the horses demonstrating a stronger “response negative than positive terms “, which is due to the importance we attach” to recognize potential threats in your environment. “
” recognizing faces of anger becomes an alarm system that enables horses anticipate negative human behaviors, “remarked the researcher.
for scientists recognizing the emotions of people is in the domestication, which would have allowed the horses fit and interpret the behavior of men and women .
the researchers said their findings show the “impact” that human behavior has on these animals.
