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 genders, the athletes demonstrated similar victorious 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 investigators to conclude thebehavior is innate. The study is in the journal Motivation and Emotion.
The researchers say the victorious bodylanguage, known as dominance threat display, may stem from an evolutionary needto display order. As in who gets to do the ordering.
