In the last two and a half decades, the concept of Emotional Intelligence has not only gained acceptance in the scientific community, but exploded all over the place, becoming a popular term used (and abused) by everyone. As the concept matured, two things happened: On one hand, more and more empirical evidence supported the concept’s applicability in a broad range of contexts and settings. On the other hand, the evidence put the early expectation of the concept in perspective, humbling pioneering claims of EI being the concept accounting for everything that traditional concepts (like intelligence, personality etc.) did not. Emotional intelligence has come of age, and as evidence explores new frontiers, practitioners explore the utility of EI-based intervention programs. So – what’s new with Emotional Intelligence? This is exactly the aim of this book – to provide readers interested in this new, promising concept, an updated view of research, and practice based on various models and views of the concept focusing on three fields in which progress seems to be most exciting: Psychophysiology and health, education and work and organizational life. Authors from around the world offer their diverse views, rich palettes of application and practice and raise questions that will lead future research and add to our understanding of the world.
