Modeling the Dynamics of Psychosis by Kinetic Logic
Forschungsbericht 95-4

Abstract
There is a growing recognition of dynamical systems approaches and process oriented
studies in clinical psychology and psychiatry. The new enthusiasm however risks turning
into dissatisfaction when facing methodological obstacles in empirical research and
mathematical modeling. Therefore graspable tools allowing a translation of current
knowledge into meaningful dynamical models could be helpful as a stepping stone.
In this paper a Boolean modeling approach and its application to the dynamics of
psychosis is presented: Kinetic Logic, originating from R. Thomas, describes systems
on an intermediate level between a purely verbal description and a description using
nonlinear differential equations. A model is introduced that describes dynamical
patterns of chronic psychosis in the context of vocational rehabilitation. Two attractor-like
dynamics of chronicity are presented. The Boolean model also proves useful in formulating
and exploring possible treatment strategies. A hypothesis about the modus operandi
of family intervention is presented.
