Abstract
This book focuses on showing how the ideas central to the new wave oj dynamic systems studies may also form the basis for a new and distinctive theory of human development where both global order and local variability in behaviour emerge together from the same organising dynamical interactions. This also sharpens our understanding of the weaknesses of the traditional formal, structuralist theories. Conversely, dynamical models have their own matching set of problems, many of which are consiously explored here. Less readily acknowledged, the youthfulness of this field means that many of the studies presented here struggle to pass beyond speculative metaphor. Nonetheless, the field is shown to be one of vigour, intelligence and great promise.
