The Motivational and Metacognitive Control in CLARION
Ron Sun · Oxford University Press eBooks · 2007
This chapter presents an overview of a relatively recent cognitive architecture and its internal control structures, that is, motivational and metacognitive mechanisms. It starts by looking at some general ideas underlying this cognitive architecture and the relevance of these ideas to cognitive modeling. In the attempt to tackle a host of issues arising from computational cognitive modeling that are not adequately addressed by many other existent cognitive architectures, CLARION, a modularly structured cognitive architecture, has been developed. A key assumption of CLARION is the dichotomy of implicit and explicit cognition. Overall, CLARION consists of a number of functional subsystems (for example, the action-centered subsystem, the metacognitive subsystem, and the motivational subsystem). The action-centered subsystem of CLARION is meant to capture the action decision making of an individual cognitive agent in its interaction with the world, that is, the primary control of actions of an agent. Thus far, CLARION has been successful in capturing a variety of cognitive processes in a variety of task domains based on this division of modules.
