"The papers in this book reflect renewed attention to an old problem; how can we understand the nature of insight? What drives the occurrence of those "Aha!" moments of breakthroughs in problem solving? Since the Gestalt psychologists first addressed the issue, there have been numerous attempts to answer it. Here, we see thoughtful new approaches -- in theory development, in methodological approach, and in the scope of problems and situations examined. The book is replete with suggestions for future research and points the way toward new cognitive understandings of insight. --Ryan D. Tweney, Emeritus Professor of Psychology, Bowling Green State University"
