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.
Amy Cuddy’s research on body language reveals that we can change other people’s perceptions and even our own body chemistry simply by changing body positions. Cuddy shouldn't have even been a scientist. When she was doing her undergraduate, she was in a car accident that severely injured her brain and doctors said she'd never fully recover.
She successfully recovered after much hard work and is now a professor and researcher at Harvard University specializing in the study of body language. Her research has shown that tweeking body language can alter your own state of mind and she gives seminars and conferences on her research and how to apply it to your own life.
