(单词翻译:双击或拖选)

You see it when you watch almost any game:there’s a touchdown, a home run, a goal. An athlete has triumphed! And then,almost instantly they raise their arms over their shoulders, shout aggressivelyand push out their chest. Like an animal in the wild or, according to a newstudy, like an athlete not simply winning, but also publicly assertingdominance.

Researchers examined footage of judoathletes from more than a dozen countries in Olympic competitions. Acrosscultures and genders¹, the athletes demonstrated similar victorious² bodylanguage.

And lest you think the behavior is observedand learned, the researchers also looked at blind Para-Olympians. They toodisplayed many of those same actions, leading the investigators³ to conclude thebehavior is innate⁴. The study is in the journal Motivation and Emotion.

The researchers say the victorious bodylanguage, known as dominance threat display, may stem from an evolutionary⁵ needto display order. As in who gets to do the ordering.
