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 some key conversations in the research.

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.
