“…He believed that system dynamics models had great potential for investigating complex economic behavior because they are logical and relatively straightforward for those who are familiar with the system dynamics notation (Day, 1982a). In his first paper on system dynamics (Day, 1974), Day explained the system dynamics vocabulary and diagramming conventions. As an example, he translated the growth model developed by MIT economist Robert Solow into the system dynamics model and identified the feedback loops in Solow's model.…”

“…Maani and Cavana, 2007;Morecroft, 2007;Sterman, 1985). The late Professor Richard Day, whose research legacy is celebrated in this special issue, advocated for using system dynamics in economic analysis (e.g., Day, 1974;Day, 1983c). Following Day's pioneering vision, we hope that this article will encourage even more economists to adopt feedback analysis.…”

This paper reports a computer simulation at the level of the organism. Freud's counterwill theory is translated into a computer model, using Forrester's system dynamics language. Three simulation runs are described to illustrate the behavior of the system in comparison with Freud's description of patient behavior. It is shown that system dynamics methodology is an effective device to expose the complex structure of psychoanalytic theory. The experimental study of psychoanalytic theory has been predominantly directed to isolated propositions.However, a system dynamics representation of the theory may stimulate academic psychology to a more comprehensive and integrated investigation of psychoanalytic theory. cc3IGMUND Freud (1892Freud ( -1893 S drew his inspiration for the counterwill theory from the case of a young "mother who was unable to feed her newborn baby till hypnotic suggestion intervened." In the present paper we develop a formalization of Freud's verbal model into a computer simulation model using Forrester's (1968) systems dynamics language. Three simulation runs are described to illustrate the behavior of the computer model as compared with Freud's description of patient behavior. The paper concludes with a discussion of the relevance of attempts to explore psychoanalytic theory with the help of system dynamics methodology.

Systems simulation. 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.
