Our primary goal is to develop a comprehensive model of human multitasking in a cognitive architecture. We are taking a bottom-up approach to this problem, starting by modeling small-scale, albeit complex, dual-task experiments. Using the ACT-R cognitive architecture (Anderson & Lebiere, 1998), we modeled the MartinEmerson and Wickens (1992) tracking and choice discrimination task (described below). By analyzing our results, we hope to gain insight and understanding into human multitasking at a low, perceptual-motor level. This will serve as a building block in the development of more general models of multitasking currently being worked on.
