This study assesses the effects of Gz stress on operator task performance and workload. Subjects were presented a two-dimensional maze on a CRT, and were required to solve it as rapidly as possible while under G-stress at levels from Gz to 6Gz. The G-stress was provided by a human centrifuge. The effects of this stress were assessed by two techniques 1 objective performance measures on the primary maze - solving task, and 2 subjective workload measures obtained using the Subjective Workload Assessment Technique SWAT. It was found that while neither moderate 3Gz nor high 5Gz and 6Gz levels of G stress affected maze solving performance, the high G levels did significantly increase the subjective workload of the maze task.
