Modeling Triple-Tasking without Customized Cognitive Control

Abstract

Cognitive models of multitasking typically use control strategies that are customized for the tasks at hand. Salvucci and Taatgen (2008) have shown that it is possible to account for dual-tasking without using customized control: they let task properties determine how tasks are interleaved. If this is how the human cognitive system tackles multitasking, it should be possible to account in the same way for more than two tasks. In the current paper we investigate whether this approach can be extended to three concurrent tasks. Two experiments are presented: a dual- and a triple-task. We show that cognitive models without fixed control strategies cannot only account for the dual-task, but for the triple-task as well.
