“Emotional intelligence is an array of personal, emotional, and social competencies and skills that influence one’s ability to succeed in coping with environmental demands and pressures.”

John Mayer, Ph.D. and Peter Salovey, Ph.D.
“[Emotional intelligence is] the ability to perceive, appraise, and express emotion accurately and adaptively; the ability to understand emotion and emotional knowledge; the ability to access and/or generate feelings when they facilitate thought (use); and the ability to regulate emotions in ways that assist thought (manage).”

Mayer and Salovey also developed the PUUM Model:

• Perceive
• Use
• Understand
• Manage

Daniel Goleman
“Emotional intelligence is the capacity not only to be aware of and able to express our emotions but to manage and moderate them effectively too. Emotional intelligence is what prevents anger from turning into rage and sadness into despair.”
