{"pk":29075,"title":"A Cognitive Modeling Approach for Predicting Behavioral and PhysiologicalWorkload Indicators","subtitle":null,"abstract":"Measuring cognitive workload is a persistent challenge in cog-nitive science. Cognitive architectures may offer a prin-cipledway to measure, define, and understand workload and its be-havioral and physiological consequences in terms ofunder-lying cognitive dynamics. Previous research has shown thatmodel-based workload relates to subjective workloadjudg-ments in simple tasks. Our goal was to further validate model-based workload measurement with known physiolog-ical work-load indicators in a complex task characterized by varying de-grees of workload levels. Participants completedan unmannedvehicle management task while their physiology was recorded.Correlations between model-based workloadand physiologi-cal metrics generally trended in the predicted direction, andthe engagement index showed the strongest andmost consis-tent relationship to model workload. The results provide pre-liminary validation for model-based workloadmeasurement.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Poster Presentations with Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/2vp8698v","frozenauthors":[{"first_name":"Christopher","middle_name":"","last_name":"Stevens","name_suffix":"","institution":"Air Force Research Laboratory","department":""},{"first_name":"Megan","middle_name":"","last_name":"Morris","name_suffix":"","institution":"Ball Aerospace","department":""},{"first_name":"Christopher","middle_name":"","last_name":"Fisher","name_suffix":"","institution":"Air Force Research Laboratory","department":""},{"first_name":"Christopher","middle_name":"","last_name":"Myers","name_suffix":"","institution":"Air Force Research Laboratory","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29075/galley/18946/download/"}]}
