You can tell a lot about a person from their body. And I don’t just mean how many hours they spend at the gym, or how easy it is for them to sweet-talk their way out of speeding tickets. For the past several decades researchers have been studying the ways in which the body reveals properties of the mind. An important subset of this work has taken this idea a step further: do the ways our bodies relate to one another tell us about the ways in which our minds relate to one another? Consider behavioral mimicry. Many studies have found that we quite readily mimic the nonverbal behavior of those with whom we interact. Furthermore, the degree to which we mimic others is predicted by both our personality traits as well as our relationship to those around us. In short , the more empathetic we are, the more we mimic, and the more we like the people we’re interacting with, the more we mimic. The relationship between our bodies reveals something about the relationship between our minds.
