The Effect of Acceleration Stress on Human Workload.

Abstract

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.
