Your body language shapes who you are
Body language affects how others see us, but it may also change how we see ourselves. Social psychologist Amy Cuddy shows how "power posing" -- standing in a posture of confidence, even when we don't feel confident -- can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success. (Note: Some of the findings presented in this talk have been referenced in an ongoing debate among social scientists about robustness and reproducibility. Read Amy Cuddy's response under "Learn more" below.)
