The present book includes papers from a wide range of topics. In the contributions to creativity research, Gruber proposes his key ideas for studying creative work. Gruber focuses on how the thinking, motivation and affect of extraordinarily creative individuals evolve and how they interact over long periods of time. Gruber's approach bridges many disciplines and subdisciplines in psychology and beyond, several of which are represented in the present volume: cognitive psychology, developmental psychology, history of science, aesthetics, and politics. The volume thus presents a unique and comprehensive contribution to our understanding of the creative process. Many of Gruber's papers have not previously been easily accessible; they are presented here in thoroughly revised form.
