Emotions influence learning, decision making, relationships, physical and mental health, creativity, and performance. Our wise use of our emotion is especially important to our success. In my presentation, I will (1) describe a component of emotional intelligence that is often overlooked – “Permission To Feel” – which includes the mindsets and attitudes we have about emotions – both our own and others; (2) describe our Center’s recent large-scale studies on the emotional lives of children and adults; and (3) share recent developments on our Center’s evidence-based approach to developing emotional intelligence in schools, RULER, which has reached over 3 million children and adults across 3,500 schools in 27 countries.
