So when we think of nonverbals, we think of 1 , how they judge us and what the outcomes are. We tend to forget, though, 2 that's influenced by our nonverbals, and that's ourselves. We are also influenced by our nonverbals, 3 and our physiology. So what nonverbals am I talking about? I'm a social psychologist. I study 4 , and I teach at a competitive business scool, so it was inevitable that I would become interested in 5 . I became especially interested in nonverbal expressions of power and dominance. And what are nonverbal expressions of power and dominance? Well, this is what they are. So in the animal kingdom, they are about 6 . So you make yourself big, your stretch out, you 7 , you're basically opening up . It's about opening up. And this is true across the animal kingdom. It's 8 primates. And humans do the same thing. So they do this both when they have power sort of chronically, and also when they're 9 in the moment. And this one is especially interesting because it really shows us how 10 these expressions of power are. This expression, which is known as 11 , Jessica Tracy has studied. She shows that people who are 12 and people who are congenitally blind do this when they win 13 . So when they cross the finish line and they've won, it doesn't matter if they've never seen anyone do it. They do this. So the arms up in the V, the chin is 14 .
