During the past 20 years, behavioral and social scientists - following advances in physics and mathematics - have shown an increasing interest in complex, adaptive, self-organizing, dynamic systems. The appeal of this perspective is fueled by the fact that there are a handful of properties that are common to all dynamic systems that can be used to explain the spontaneous emergence of novel forms, the mechanisms of continuity and change, and the dynamics of a large number of interacting factors. From animal population dynamics to human neural processes, there is growing evidence that human...
