Abstract

We investigate the implications of an episodic versus semantic memory representation in a model of serial task switching. Altmann and Gray (2002; 2004) have developed a model in which the rate of memory activation, decay, and interference are tightly coupled in an explanation of learning, forgetting, and performance. A central assumption of their model is the use of an episodic memory trace for task cues. The current research explores the centrality of this assumption by exploring the predictions made by three mathematical formulations of interference and decay.
