Self-Determination Theory

"This valuable volume presents a synthesis of four decades of systematic work within one of the most comprehensive, profound research programs on human motivation in the history of psychology. It is a true milestone in motivational research, as rich in conceptual insights as it is in exciting findings. The book offers a formidable set of answers as to why people do what they do, and with what consequences. An assured and instant classic!"--Arie W. Kruglanski, PhD, Distinguished University Professor, Department of Psychology, University of Maryland, College Park

"This book is a tour-de-force exposition of the motivational nutrients needed for optimal human growth and well-being. It is global in scope, while also replete with applications to specific contexts. SDT and its mini-theories are characterized by astonishing scholarly vitality and depth of thought, combined with unrivaled relevance for everyday life at all levels of society. Taken as a whole, the advances summarized in this volume have transformed what we know about human behavior and development.”--Carol D. Ryff, PhD, Hilldale Professor of Psychology, University of Wisconsin–Madison

"Ryan and Deci have produced a treasure for those who want to understand the basis of human motivation and learn how to improve societies. What a resource! The book carefully explains SDT and the research supporting it, including the role of universal needs, intrinsic motivation, and growth. Importantly, the volume addresses how we can use SDT to improve schools, health care, family life, psychotherapy, work, sports--nearly every aspect of social life. It is no wonder that the SDT movement is spreading around the globe."--Ed Diener, PhD, Professor of Psychology, University of Virginia and University of Utah

"A masterful, comprehensive explication of the tenets of SDT. The authors demonstrate a keen sense of history and respect for their intellectual ancestors, stepping only lightly on a few theoretical toes. The theoretical claims that comprise SDT are coherently documented by a plethora of well-crafted and ingenious laboratory and real-world research studies. A major contribution is the compelling practical application of the theory to numerous life domains, including classroom teaching, the workplace, psychotherapy, and others. There is great wisdom in these applications. The breadth of topics will make this volume attractive to researchers, clinicians, educators, and sports and organizational psychologists."--Susan Harter, PhD, John Evans Professor of Psychology (Emerita), University of Denver
