Swapping bodies

This experiment (succintly described by Ed Yong) is possibly the craziest psychology experiment i have ever heard of, and very very cool. In brief, a couple of psychologists, using pretty simple camera setups and mannequins, convinced people that a mannequin's body (and then another human's body) was their own. Eventually, the subjects were so convinced that these other bodies were their own that when the mannequin bodies were threatened with a knife, their own bodies showed typical physiological fear and stress responses (sweat on the neck, etc.). Brings up so many interesting issues and implications about how we sense the world and ourselves in it, video games and reality, I don't even know where to begin. Maybe I should rename this blog "we are living in the future."
