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 Joy Casselberry Cuddy is an American social psychologist known for her research on stereotyping and discrimination, emotions, power, nonverbal behavior, and the effects of social stimuli on hormone levels. She is Associate Professor of Business Administration in the Negotiation, Organizations & Markets Unit at Harvard Business School. Her TEDTalk, delivered at TEDGlobal 2012 in Edinburgh, Scotland, and posted in October 2012, has been viewed more than 16 million times and ranks among the top 15 most-viewed TEDTalks.
