When, why, and how are people motivated? This is the essential question that motivation science has sought to address since the field's inception, and yet motivation scientists have offered many contrasting and even conflicting perspectives that have stalled key conversations in the research. This volume captures the nature of these critical debates, while also moving the field towards greater coherence by bringing differing perspectives from experts together in one volume. Posing 10 fundamental questions to 57 prominent motivation researchers around the globe, Motivation Science: Controversies and Insights covers topics such as the nature of motivation, cultural differences in motivational processes, evidence-based strategies to enhance motivation, and predictions for the future of the field. Edited by three leaders in motivation science, this volume provides readers with a rare opportunity to see how different theorists and researchers recognize, evaluate, and prescribe solutions to the same motivation problem. By sharing current thinking and providing innovative insights into the important questions and controversies in the study of motivation, the book brings together cutting-edge theory and research that readers can use to generate fresh and effective applications and interventions.
