Modeling the Workload Capacity of Visual Multitasking


We utilize the capacity coefficient to characterize the workload capacity of visual multitasking. The capacity coefficient compares cognitive work completed on multiple information sources against a baseline parallel model prediction. Capacity coefficient results subsume standard mean response time (RT) dual-task findings while providing a description of workload effects on the whole RT distribution. This yields a theoretically-grounded characterization that can inform computational and process models of multitasking.
