“…On the purely cognitive level, quite similar mechanisms are already implicit in Piaget's concepts of the evolution of mental structures. Early systematic investigations along these lines in the field of schizophrenia have already brought some encouraging results (Schiepek et al, 1992;Ciompi et ai, 1992;Ambiihl et ai, 1992). Here, as well as in the other areas mentioned, the integrative concept of affect logic seems capable of providing a useful theoretical framework for future research and practice.…”

The integrative concept of ‘affect logic’ is based on a hypothesis concerning the laws of interaction between emotion and cognition. ”Affects“ are defined as global psychophysiological states which determine the prevailing functional ‘logic’, i.e. the specific ways in which cognitive elements are selected and linked together. This leads to an integrative psychosocio-biological evolutionary model of schizophrenia, in which a specific affective–cognitive vulnerability is built up in a first phase, through escalating interactions between unfavourable genetic–biological and psychosocial influences. In a second phase, the mental system is decompensated by psychosocial or biological stressors which induce psychosis. The great variability in long-term course (third phase) is conditioned by the complex interplay of many biological and psychosocial variables. The organising functions of affects are evident in schizophrenic core phenomena such as ambivalence, incoherence, and emotional flattening. This proposed model has numerous practical and theoretical implications.

“…Müller and Ciompi [30], for instance, who observed long-term courses of schizophrenia over years, found various patterns which cannot be easily explained by a common mechanism of symptom generation. In addition, Schiepek et al [35] modeled the interaction of psychological variables like anxiety, stress, delusion etc., in a computer-based simulation and they were able to demonstrate these time courses by changing the coupling weights of these variables ( Fig. 1).…”

Progress in the pharmacological treatment of schizophrenia is dependent on the extent of our understanding of the brain as the basis of this disease. Detailed examination of neurobiological data shows that only a systemic approach will integrate this wealth of information. For this reason, the steps involved in model building should be clarified, as further progress will necessitate closer cooperation between neuropsychiatrists, neurobiologists and systems scientists.

“…This stepwise procedure was developed basically in the context of systems dynamics with regard to the development of the theoretically fruitful socio-ecological “world models” ( Meadows et al, 1972 ; Sterman, 2000 ; Meadows and Wright, 2015 ). This procedure has already been applied within exploratory computer simulations several times for psychiatric disorders ( Schiepek et al, 1992 ; An der Heiden et al, 1998 ; Tretter and Scherer, 2006 ). Interestingly, an integrative systems dynamics model of depression was published recently ( Wittenborn et al, 2016 ).…”

Clinical fields of the “sciences of the mind” (psychotherapy, psychiatry, etc.) lack integrative conceptual frameworks that have explanatory power. Mainly descriptive-classificatory taxonomies like DSM dominate the field. New taxonomies such as Research Domain Criteria (RDoC) aim to collect scientific knowledge regarding “systems” for “processes” of the brain. These terms have a supradisciplinary” meaning if they are considered in context of Systems Science. This field emerges as a platform of theories like general systems theory, catastrophe theory, synergetics, chaos theory, etc. It provides a lot of abstract concepts, constructs, methods and models. We assume that these tools also enable theoretical integration in the diversified field of clinical practice in the sciences of the mind. Additionally, systems thinking in clinical psychology improves conceptual links to currently network-oriented neurobiology. However, clear definitions of systemic terms are necessary to emerge from their mainly metaphorical use. Here we revise mainly terms like “structure”, “process” and “dynamics” as they are used already in psychology, psychoanalysis, psychopathology and psychiatry in an ill-defined way. For instance, affective-cognitive structures like “life space” or “object representations” can be seen as products of mental processing. These structures, in turn, modulate dynamics of mental processes. Additionally, we suggest a coupled network concept of emotions and motivations as the main subsystem that modulates mental dynamics that results in a qualitative systemic model of the mind. Finally, we assume that a revisited systemic approach could improve interdisciplinary understanding of the mental.
