[custom_adv] Emotional intelligence is generally said to include at least three skills: emotional awareness, or the ability to identify and name one’s own emotions; the ability to harness those emotions and apply them to tasks like thinking and problem solving; and the ability to manage emotions, which includes both regulating one’s own emotions when necessary and helping others to do the same. [custom_adv] Emotional intelligence (EI), emotional leadership (EL), emotional quotient (EQ) and emotional intelligence quotient (EIQ), is the capability of individuals to recognize their own emotions and those of others, discern between different feelings and label them appropriately, use emotional information to guide thinking and behavior, and manage and/or adjust emotions to adapt to environments or achieve one's goal(s). [custom_adv] Although the term first appeared in a 1964 paper by Michael Beldoch, it gained popularity in the 1995 book by that title, written by author and science journalist Daniel Goleman. [custom_adv] Since this time, EI, and Goleman's 1995 analysis, have been criticized within the scientific community,despite prolific reports of its usefulness in the popular press. [custom_adv] Empathy is typically associated with EI, because it relates to an individual connecting their personal experiences with those of others. [custom_adv] However, several models exist that aim to measure levels of (empathy) EI. There are currently several models of EI. Goleman's original model may now be considered a mixed model that combines what has since been modeled separately as ability EI and trait EI. [custom_adv] Goleman defined EI as the array of skills and characteristics that drive leadership performance. The trait model was developed by Konstantinos V. Petrides in 2001.
