Model types and explanatory styles in cognitive theories

In this paper we argue that the debate between representational and anti-representational cognitive theories cannot be reduced to a difference between the types of model respectively employed. We show that, on the one side, models standardly used in representational theories, such as computational ones, can be analyzed in the context of dynamical systems theory and, on the other, non-representational theories such as Gibson’s ecological psychology can be formalized with the use of computational models. Given these considerations, we propose that the true conceptual difference between representational and antirepresentational cognitive descriptions should be characterized in terms of style of explanation, which indicates the particular stance taken by a theory with respect to its explanatory target.
