Abstract
This experiment investigated the workload associated with both a consistently mapped (CM) and variably mapped (VM) version of a memory/visual search task that required the processing of spatial pattern information representative of that found with some Command and Control (C2) systems. A secondary loading task paradigm which required concurrent performance of an additional spatial pattern search task was employed. The results demonstrated superior dual-task performance relative to single-task baselines on both the primary and secondary tasks when the CM version of the task was performed. The results indicate that the development of automatic processing through training can reduce the workload associated with processing spatial patterns of the type employed by C2 operators.
