Men face more aggressive

Men with bigger faces are also more offensive, a new study of hockey players reveals.

Men are generally wider than women - a gender difference derived from puberty when testosterone levels rise. At the same time, testosterone is associated with aggression, causing researchers to suspect a link between aggression and wide face.

The Canadian team studied photos of professional hockey players as well as amateurs, measuring the width and length of their faces. The team found that the more the face looked, the more aggressive the athlete was, the number of minutes they were punished for aggressive behavior.

"One particular thing about hockey is that you can express your aggressive behavior in an acceptable way. And that's why it became a good model to learn about aggression. " , Justin Carré, behavioral neurologist at Brock University in Canada, said.

In addition, the team examined 88 college students through a computer game. These people are required to compete with a competitor of the same gender (actually a computer). In the game, they can press a button to add points, another button to protect their points from being stolen, and the last button to steal points aggressively from the opponent's hand.

Researchers discovered that large faces are associated with aggression, but only in men, not women.

One limitation of this study is based on portraits, not on real faces. The expression of the face depends on how the head is lifted. In addition, researchers still do not know whether people really feel this personality on large faces.
