Part of this is due to the reliance of building models based on similar training tasks that enable detection of comparable neural indicators. As such, many workload prediction systems currently rely on tasks of similar design and interaction targeting specific cognitive functions. To address this, we developed personalized models in our study from a battery of standard cognitive tasks and mapped them to a dynamic operational environment, requiring simultaneous use of a combination of these cognitive functions. We first discuss the design of the baseline battery of cognitive tasks and how the components translate to a more dynamic two-person mission. We selected and modified the following six standard cognitive workload tasks to comprise a 60-minute baseline battery assessment: Stop Signal Task, Conjunctive Continuous Performance Task (CCPT), Spatial Span Working Memory Task, Trail Making Task (TMT), Situation Awareness Global Assessment Technique (SAGAT), and Balloon Analogue Risk Task (BART). All tasks were adapted in at least two ways: (1) timing and number of trials to support use of functional neuroimaging with block design and enable 60-minute max across all 6 tasks; and (2) visually to reflect icons and styles expected in the final task. We then evaluate the effectiveness of the workload-based performance predictions for each cognitive function in guiding task reassignment in a two-person mission, as compared to reassignment based on performance alone. The two-person mission is composed of multiple interrelated subtasks with the overall goal of finding and identifying as many targets as possible in the time allowed. Each of the subtasks will require use of one or more cognitive functions, mapping to those tested in the baseline battery. By including workload indicators across the cognitive functions, we anticipate enabling reassignment prior to performance reduction, allowing for overall increase in performance while maintaining sustainable workload across the teammates.
