Research at the Naval Research Laboratory (NRL) has shown that the use of auditory cueing can
dramatically improve operator performance in dual-task environments for which efficient task-switching plays a
crucial role (Ballas, 1992, Brock, 2004, Brock, 2006). In order to better exploit the benefits of auditory cueing for the
purpose of attention management in multitasking environments, the Navy desires a model-based understanding of the
mechanisms driving human performance in these scenarios. Empirical studies utilizing a complex dual task and
related cognitive modeling work developed with the EPIC cognitive architecture [5], have focused on understanding
the methods subjects employ to effectively time their transitions between tasks. These models support the notion that
time spent on the primary, relatively stateless, tracking task is regulated by state information retained from the
secondary, radar task. However, the models do not sufficiently capture the benefits observed in conditions utilizing
auditory cuing to assist in attention management. A minor modification to these models results in a dramatic change
in model performance, provides insight into when and how auditory cues provide benefit, and raises questions about
the methods used by the models to time attention switches between tasks.
