“The nonlinear dynamical approach provides an innovative way of understanding the real, complicated systems at the very heart of social psychology. The value of this approach is convincingly demonstrated in this well-written book. Nowak and Vallacher use many of their own original experiments and simulations to put topics such as social understanding and cognition, social influence, and interpersonal and group behavior into this new framework. This text is 'must' reading for all social psychologists—even the most traditional among us—who wish to stay abreast of the times.”

“'She loves me, she loves me not...' Social life is known for its changes, and for the changes that it puts us through. This book uses dynamical systems methods to capture such change processes in essential areas of social psychology. The ideas run thick and fast as the authors lay out in a most readable style how the new science of change illuminates topics from self and close relationships to social judgment and influence.”

“Individual behavior is governed by a complex set of phenomena, and the behavior of collectivities is even more complex. To effectively approach these areas of study, social scientists must seek to extract patterns and uniformities out of this complexity. It is a feat of some elegance that Nowak and Vallacher have succeeded in applying their methodology to the simplification—but not oversimplification—of complex collective systems. These authors are to be commended for their contribution.”
