“Even blind children make this same face without ever having seen one,”Aaron Sell,who led the study,told the DailyMail.
The angry expression is made by seven muscle groups.Researchers wanted to understand why those seven muscle groups were chosen,so they did a series of experiments.
They took a photo of a human face.Then they used a computer to change the face in two ways:One photo showed a lowered brow,and the other a raised brow.They showed the photos to people.
With just this one difference,neither face looked “angry”.But people reported the face with the lowered brow could be from a stronger man.
Researchers did the same experiment with each of the other six features of an angry face:raised cheekbones (颧骨),lips thinned and pushed out,the mouth raised,the nose wide open and the chin pushed out and up.
People all reported the same feeling:The person making the face was physically stronger.
“Since stronger people tend to get their way more often...we found that it (the anger face) is a threat display,” said Sell.
Many other animals also do the same thing.When a dog wants to protect its food,it shows its sharp teeth.Even a small frog knows to puff (膨胀) itself up if it sees possible danger coming.
Researchers also point out that anger is a bargaining tool.We make that face to let others know:“The event is not acceptable,and the conflict will not end until we reach an agreement.”
