Performance Assessment in Sustained Operations Using a Computer-Based Synthetic Work Task

Abstract : Prediction of the effects of stressors on military performance from laboratory tests frequently involves use of procedures simulating critical functional aspects of military jobs. This paper presents a computerized 'Synthetic Work' test, SYNWORKI, as a prototypical alternative to traditional Performance Assessment Batteries. This test simulates complex operational environments by requiring subjects to work on four simultaneous tasks, and assigns explicit consequences for work on each component task. As illustrations of the utility of this technique, data are presented from three applications of SYNWORK1, a laboratory study of sleep deprivation, a test of extended exposure to a simulated sonar 'ping', and the use of the same task during army operations in Operation Desert Storm.
