In Sync: The Emergence of Function in Minds, Groups and Societies (Understanding Complex Systems) by Andrzej K. Nowak

This book introduces the reader to the concept of functional synchronization and how it operates on very different levels in psychological and social systems – from the emergence of thought to the formation of social relations and the structure of societies.

For years, psychologists have investigated phenomena such as self-concept, social judgment, social relations, group dynamics, and cooperation and conflict, but have discussed these phenomena seoarately.This book shows how synchronization provides a foundational approach to these otherwise distinct and diverse psychological processes.This work shows that there is a basic tendency with many processes to become coordinated and progressively integrated into increasingly larger units through well-defined processes. For these larger units, new and largely adaptive functions emerge. 

Although synchronization affords progressive integration of system elements to enable correspondingly higher-order functions, the trajectory of synchronization is often characterized by periods of assembly and disassembly of system elements. This occurs when a task is completed and synchronization is no longer essential so that the elements once again operate in an independent fashion. It is argued that the disassembly-resynchronization scenario occurs at all levels of psychological and social reality. The implications of this approach for important issues in interpersonal relations and societal processes are discussed.
