This book is relevant for anyone involved in the practice of psychology and the social sciences more broadly: researchers, teachers, students, and practitioners. It challenges the status quo with regards to the way that psychology is done, and it offers a unified solution that encompasses both theory and methodology.

Cramer et al.'s article is an example of the fruitful application of complex dynamic systems theory. We extend their approach with examples from our own work on development and developmental psychopathology and address three issues: (1) the level of aggregation of the network, (2) the required research methodology, and (3) the clinical and educational application of dynamic network thinking.
