Your Body Language

Amy Cuddy: 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.

Amy Cuddy studies the origins and outcomes of how people judge and influence each other. She has conducted experimental and correlational research on stereotyping and discrimination against various groups (e.g., Asian Americans, elderly people, Latinos, working mothers), the causes and consequences of feeling ambivalent emotions (e.g., envy and pity), nonverbal behavior and communication, and hormonal responses to social stimuli.

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. Cuddy holds a PhD in Social Psychology from Princeton University, an MA in Social Psychology from Princeton University and a BA in Social Psychology from the University of Colorado.
