Computer simulation of Freud's counterwill theory: extension to elementary social behavior

A model is presented describing decision processes of a living system at the level of the individual, together with its interpersonal relationship context (organism, subsystems, and suprasystem). The beginning point was the 1977 system dynamics model of Wegman, which was itself characterized by quantitative cross-level hypotheses concerning both physiological and psychological levels of functioning within the individual personality system. The extension process was accomplished by synthesizing concepts from many different theories in personality and social psychology into equations linking two multiple-loop feedback systems to form a suprasystem. Each individual model was found to have several distinct operational modes, and the dyadic model had a number of interesting combinations of these modes which correlated with clinical descriptions of steady-state behavior and subjective experience in human marital dyads. For example, under certain conditions an individual operating in an unstable mode could achieve personal system stability within a dyadic relationship. In some cases, two unstable individuals could form a stable system. The process of extending the original model supports the utility of a synthetic approach to the construction of quantitative theories concerning small social systems. This process also suggests new approaches to planning future empirical research on small social systems using methods more appropriate to the study of complex, dynamic systems.
