Eye tracking insights into cognitive modeling

Abstract

The original 2000 AMBR project sought to evaluate how well four human performance models simulated behavior of human participants. Participants and models completed a modified version of an air traffic control task and were compared on the dimensions of performance, reaction time and subjective workload ratings. The current study replicated the human performance findings of the previous phase of AMBR and added eye tracking analysis to enhance understanding of participants' behavior. Examination of gaze position and patterns of eye movement provided evidence that participants adopted different visual strategies to complete the task in different display conditions and at different levels of demand. Applicability of eye tracking analyses to cognitive models is discussed.
