As the first science-based introduction to the topic, this latest addition to The Psych 101 Series discusses one of the most pivotal new psychological concepts of the 21st century: emotional intelligence (El). The text provides an even-handed appraisal of those aspects of El that have been substantiated by scientific evidence and those areas that require more rigorous scrutiny. It explores the promise of El regarding the treatment of mental illness and the enhancement of normal functioning while examining conceptual and empirical tests that must be satisfied before El can be accepted as a major new aspect of individual differences. The text identifies two different pathways of research-one concerned with El as a true ability, the other viewing El as more akin to a personality trait. It examines the role of personality traits in emotional functioning and considers strategies for assessing El as an ability using objectively scored tests, along with potential pitfalls to conducting valid research, The implications and consequences of both high and low El regarding functioning in real life are discussed, including the relationship of El to psychopathology. The book also surveys and evaluates training programs directed toward improving emotional functioning in the classroom and the workplace, and assesses those improvements in research methods that are needed. Discusses how El can improve learning in school and enhance important work skills such as communication and teamwork. Covers key research issues, including methods for measuring El, its overlap with conventional ability and personality traits, and the validity of testing for El. Reviews applied studies and the contributions that research on El may make to address real-world personal and societal problems. Examines the main conceptual, measurement, and research issues identified in various lines of research, most conducted within the last 10 years.
