Your Body Language Shapes Who You Are
We know that in primate hierarchies, if an individual needs to take over an alpha role sort of suddenly, within a few days, that individual’s testosterone has gone up significantly and his cortisol has dropped significantly.
We have this evidence, both that the body can shape the mind, at least at the facial level, and also that role changes can shape the mind.
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 says that when someone is being really powerful non verbally that we don’t actually mirror them, we do the opposite of them.
