Emotional intelligence was developed as a psychological theory by Peter Salovey and John Mayer. They defined it as the ability to perceive, understand, and manage emotions. Daniel Goleman later expanded on this work and identified five components of emotional intelligence: self-awareness, self-regulation, internal motivation, empathy, and social skills. Spiritual quotient is emerging as a new concept that measures a person's spiritual intelligence in a similar way to how IQ measures cognitive intelligence. It refers to the ability to recognize intelligence beyond the five senses through awareness, contemplation, and prayer.
