Insights into Working Memory from the Perspective of the EPIC Architecture for Modeling Skilled Perceptual-Motor and Cognitive Human Performance

Computational modeling of human perceptual-motor and cognitive performance based on a comprehensive detailed information-processing architecture leads to new insights about the components of working memory. To illustrate how such insights can be achieved, a precise production- system model that uses verbal working memory for performing a serial memory span task through a strategic phonological loop has been constructed with the Executive-Process/Interactive-Control (EPIC) architecture of Kieras and Meyer. EPIC is characterized by five central features that may be compared and contrasted with those of other theoretical frameworks in this volume. These features include:
