Various 'schools' with different theories and concepts exist in this field of clinical psychology. It is clear that explanations of a person's state and of the change of his state and behavior can be focused on aspects (or a network of aspects) such as basic inherited structures, biochemical and neuronal processes, muscular and general physical constitutions, experiences and the ways to store them, style of familial interaction, economic situation, social values and norms etc. For this reason, we may deny neither the influence of such aspects nor the valuable contribution of other approaches to our understanding of clinical phenomena. Nevertheless, for our present purpose it remains fair to focus on the so-called 'systemic" approach to clinical psychology and to discuss some ideas concerning the application of synergetics to this approach. To provide a basis for the following considerations, it might be of value to start with brief review of some basic concepts of systemic clinical psychology.
