In the area of psychology, many different scientists explained emotional intelligence in a variety of ways. Today, the most commonly used are the model of Mayer and Salovey and the model of Bar-On. The model of Salovey and Mayer includes assessment and expression of emotions, perception, emotional facilitation of opinion, understanding and analysis of emotions and reflective regulation of emotions.Evaluation and expression of emotions, as well as perception, are actually the ability of recognizing emotion in physical condition, works of art, linguistic expression and behavior. By learning to recognize his/her own and others' emotions, a person is able to distinguish the real emotion from the false one. The emotional facilitation of opinion refers to the knowledge of the impact of emotion on memory and thinking. A person who developed this ability is able to clearly recognize the emotions and to use them in judgement. In this case, emotions facilitate an approach to a specific problem, as well as the development of creativity.The understanding and analysis of emotions enable the use and development of emotional knowledge. The person who has this ability can clearly name the emotions and recognize the relationships between the words (e.g., to like and to love) and consequently he/she understands the consequences of these emotions. This component can strengthen and the result is the understanding of more complex emotions, as well as the ways emotions switch from one to another. In short, this component can be described as the ability of recognition of certain laws related to emotions.The model Bar-On is designed by Israeli scientist Reuven Bar-On. His model consists of 15 components grouped into five main groups: intrapersonal components, components, interpersonal components, adaptability components, stress management components and general mood components. Intrapersonal component includes an emotional self-consciousness whose purpose is to understand yourself and others. Interpersonal component includes empathy, i.e. the ability of noticing how people feel in our environment. Stress management component refers to the stress tolerance. People who are tolerant to stress know how to act under pressure and they control a specific situation more easily.
