Towards a Formal Foundation of Cognitive Architectures

AbstractCognitive architectures are an advantageous tool for creating cognitive models. They provide a framework integrating general cognitive structures and assumptions about the mind as for example the working memory, structural modularity or their interconnections. A vast number of cognitive architectures have been developed in the last decades. While the architectures realize the cognitive perspective, the formal foundation and similarities of cognitive architectures remain open. To identify the cognitive substrate of the architectures, we propose a generalized cognitive framework allowing to embed different cognitive architectures to analyze their properties and to have a common and formal ground for comparisons. We demonstrate our approach -- as proof-of-concept -- by embedding the two most popular architectures, ACT-R and SOAR, and evaluate cognitive models for recognition memory in our approach. Potentials and limitations are discussed.
