Unitary Theories of Cognitive Architectures
CEC Joint Research Centre, Ispra, Italy
Unitary theories of cognitive architectures have been suggested as “grand theories” of human cognition. Models of human cognition have been developed in order to predict human behavior through computer simulation. This chapter review three models, each based on unitary theories: Soar (Newell, 1990), ACT* (Anderson, 1983), and the Underspecification Theory (Reason, 1990). The notion of symbol systems is used as a guideline for specification of architectures, and specific attention is paid to the models as systems for information processing. Each of the models is briefly outlined, and the main components are discussed. Examples of research on ...
