Navy watchstanding operations increasingly involve informationsaturated
environments in which operators must attend to more than one critical
task display at a time [1]. In response, the Navy is pursuing a model-based
understanding of human performance in multitask settings. Empirical studies
with a complex dual task and related cognitive modeling work in the authors’
lab suggest that auditory cueing is an effective strategy for mediating operators’
attention [2,3,4]. Characterizing the effects of widely separated displays on
performance and effort is an important ancillary concern, and a series of
cognitive models developed with the EPIC cognitive architecture [5] is used for
this purpose. These cognitive models verify a key finding from an empirical
study; namely, time spent on the primary, relatively stateless, tracking task is
regulated by state information retained from the secondary, radar task. These
findings suggest that in multitask settings, operators use relatively simple state
information about a task they are about to leave to gauge how long they can
attend to other matters before they must return.
