"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
