AN OVERVIEW OF THE EPIC ARCHITECTURE FOR COGNITION AND PERFORMANCE WITH APPLICATION TO HUMAN-COMPUTER INTERACTION

EPIC (Executive Process-Interactive (Control) is a cognitive architect ure especially suited for modeling human multimodal and multiple-task performance. The EPIC architecture includes peripheral sensory-motor p rocessors surrounding a production-rule cognitive processor and is bei ng used to construct precise computational models for a variety of hum an-computer interaction situations. We briefly describe some of these models to demonstrate how EPIC clarifies basic properties of human per formance and provides usefully precise accounts of performance speed.
