Deborah Gruenfeld, formerly of Stanford Graduate School of Business, studied the impact of non-verbal behavior on perceptions of power.

She reported that people who “occupy space” are viewed as more dominant and powerful by others.

She demonstrated that non-verbal behavior like erect, “space-occupying” postures and selective smiling affect the way the person executing these behavior feels about his or her personal power, competence, and mood.

“Power postures” affect secretion of hormones associated with dominance (testosterone) and stress (cortisol).

Effective leaders and recently promoted leaders show a hormone profile of high testosterone and low cortisol, indicating high dominance and low stress.

Individuals in low power role have low testosterone and high cortisol, and this trend is more common among women.

Posture can make a large difference in how people view themselves, how others see them, and their opportunities and outcomes.

Before a job interview or stressful interaction, a “big power posture”  can increase confidence and performance.
