Emotional intelligence refers to the ability to recognize and manage emotions in ourselves and in our relationships. There are three main models of emotional intelligence: ability, mixed, and trait. The ability model focuses on accurately perceiving, using, understanding, and managing emotions. The mixed model developed by Daniel Goleman emphasizes emotional and social competencies important for leadership. Research has found emotional intelligence correlates with important work outcomes like job performance, decision-making, creativity, and leadership effectiveness. Assessing and developing emotional intelligence can benefit organizations in areas such as selection, motivation, negotiation, and customer service.
