Do our bodies change our minds?

Amy Cuddy is a social psychologist and an associate professor at Harvard Business School.  In this Ted talk, she argues that our non-verbal body language effects not only how others view us, but how we view ourselves.  Even more impressively, she shows that by changing our posture for just 2 minutes changes our mind:  our hormone levels (testosterone and cortisol levels), increases our appetite for risk, and causes us to perform better in job interviews. In short, as David Brooks summarized the findings, “If you act powerfully, you will begin to think  powerfully.”
