New study finds goats prefer happy human faces

Washington: Turns out, Goats can differentiate between human facial expressions and prefer to interact with happy people.

A new study led by scientists at the Queen Mary University of London provides the first evidence of how goats read human emotional expressions, implies that the ability of animals to perceive human facial cues is not limited to those with a long history of domestication as companions, such as dogs and horses.

The team described how 20 goats interacted with images of positive (happy) and negative (angry) human facial expressions and found that they preferred to look and interact with the happy faces.

Dr Alan McElligott who led the study said, "The study has important implications for how we interact with livestock and other species because the abilities of animals to perceive human emotions might be widespread and not just limited to pets."

The team found that images of happy faces elicited greater interaction in the goats who looked at the images, approached them and explored them with their snouts. This was particularly the case when the happy faces were positioned on the right of the test arena suggesting that goats use the left hemisphere of their brains to process positive emotion.

First author Dr Christian Nawroth said, "We already knew that goats are very attuned to human body language, but we did not know how they react to different human emotional expressions, such as anger and happiness. Here, we show for the first time that goats do not only distinguish between these expressions, but they also prefer to interact with happy ones."

The research has implications for understanding how animals process human emotions.

"Our results open new paths to understanding the emotional lives of all domestic animals," said Co-author Natalia Albuquerque.

The full findings are present in the journal- Royal Society Open Science.
