The focus of this Handbook is on the development, nurturance, and enhancement of creative processes and creative achievement across the lifespan. What do we currently know about the development of creativity? How can we develop the processes important for creative thinking, and how can we help individuals translate that creative potential into creative achievement throughout their lives? We are pleased that leading scholars and researchers in the field agreed to contribute to the Handbook and share their perspectives. There are 25 chapters addressing a variety of topics in the area. This Handbook provides a review of each area, including current research findings, consensus in the literature, best practices in each area, and key questions for future research. In addition, many chapters raise provocative questions that point the way for future consideration and research.
