Abstract: "A runnable simulation architecture for working memory is described that provides an alternative to existing models of working memory, e.g., of Atkinson and Shiffrin (1968) and Baddeley (1986). It is used to interpret a variety of phenomena, including multiple resources, workload, chunking, sequential output, skilled and episodic memories, and stages of skill acquisition. The architecture is based on a set of modules organized into regions which communicate with each other on an innerloop of processing.A new feature of this architecture is a proposed context-storage module that temporarily stores context information in fast changing connection weights. This enables the system to expand effective working memory beyond the traditional 7 [plus or minus] 2 items. The context storage system is able to reload modules after short-term information decays or is displaced; in addition, it provides a means of achieving stable, robust processing under conditions of high workload."
