Cognitive Metrics Profiling

Cognitive metrics profiling promises a new approach to minimizing the cognitive workload of interactive systems. By metering high-fidelity computational cognitive models of embodied cognition, Cognitive Metrics Profiles provide a theory-based prediction of the transient changes in workload demanded by dynamic task environments. Although establishing the reliability and validity of this new approach will not be trivial, our profiles stand on the shoulders of the ACT-R architecture of cognition. More than 30-yrs of research have gone into the ACT line of theories. Over the last decade, hundreds of researchers have used ACT-R to build and test models of human cognition. Hence, although many of the details of the architecture are certainly incomplete, much of ACT-R is approximately correct. We expect that the predictions of a cognitive metrics profile based on ACT-R will provide a better estimate of cognitive workload than the post-hoc or subjective estimates used in current human factors practice.
