Cognitive and computer models of physical systems

Abstract

Models of physical systems range from those of initial individual cognition to mathematical representations on a computer which are accepted as the developed final models. It is conjectured that a formalization of the qualitative cognitive models will help us to understand how they are formed and will eventually help us to produce better computer models. The structure of these models would provide qualitative descriptions and explanations of behaviour which could be assimilated by non-specialists. It is argued that cognitive models should be produced with an awareness of the possible form of the final computer model. To illustrate this, a case study of the development of the cognitive and computer models of a naturally parallel physical process is presented. This early work is part of the broader goal of producing an appropriate computing environment through which various models and techniques are combined for producing explanations. A procedure for developing models from the primitive stage to computer implementation is suggested. Theories in cognitive science and research on mental models are briefly discussed.
