dc.description.abstractTwo new applications of established techniques for measuring an individual's level of stress (workload) in tracking tasks are presented. An indirect technique of measuring "reserve capacity" is utilized in a two-axis cross-coupled compensatory tracking task. A direct psychophysiological measurement is made by recording time histories of operator pupil diameter. Results obtained indicate that each method yields a good index of workload, although considerable variance in the data is observed. The level of instability in the second axis of the cross-adaptive method is shown to be related to the level of workload in the primary axis. Increased pupil diameter is shown to be similarly related, to operator workload. The simultaneous application of both techniques is determined to be inappropriate.
