In this book, we have brought together cutting-edge dynamic systems research concerning adolescent development. In doing so, our general aim was to demonstrate how a dynamic systems approach can uniquely move the field of adolescent development forward. With the various chapters in this book, we have demonstrated how dynamic systems principles have led to new theoretical and empirical contributions in many domains particularly important to adolescent development, such as sexuality, identity, and moral development, as well as insights into the dynamics and process characteristics of the period of adolescence in general. Here we first provide an overview of the chapters, then discuss the commonalities and differences in the chapters with respect to their application of the broad dynamic systems approach, and finally, draw conclusions regarding the contribution, limitations, and future directions of dynamic systems research.
