This excellent book is unique in bringing together a very diverse group of authors who have something interesting to say about self-regulation or executive functioning and its relation to social understanding and social interaction. The authors vary in their perspectives, their approaches, and their foci, but together provide a stimulating, nuanced, and multifaceted review of theory and findings on self-regulation and executive functioning. Even an expert on the topic is likely to learn much about new approaches and empirical findings. This book will be very useful to researchers, students, and practitioners interested in the development of self-regulation and executive functioning. - Nancy Eisenberg, Regents' Professor, Department of Psychology, Arizona State University
