Vigilance or sustained attention is a critical aspect of many jobs including air-traffic control, airport security, industrial quality control, and medical screening/monitoring. Traditional approaches to personnel selection for tasks requiring sustained attention have focused on sensory acuity, aptitude, sex, age, and personality measures. However these approaches have been ineffective. The present study attacked the selection issue in an innovative manner by using responses to a brief 10-min screening battery involving high workload tracking, verbal working memory, and line discrimination tasks to predict performance on a subsequent vigilance task. The latter simulated an air-traffic control task and was composed of four consecutive 9-min periods of watch. Two predictors of interest were cerebral blood flow velocity (CBFV), measured via transcranial Doppler ultrasonography (Warm & Parasuraman, 2007), and subjective state, as indexed by the Dundee Stress State Questionnaire (DSSQ; Matthews, et al; 2002). The results testify to the importance of assessing task-induced responses for predicting vigilance performance. They also indicate that forecasting vigilance performance is a complex endeavor requiring a set of multidimensional predictors. Specifically, multiple regression (R = .358) indicated that higher levels of CBFV in the left and right hemispheres and higher post-battery task engagement scores on the DSSQ during performance of the screening battery predicted perceptual sensitivity (A’) during the final period of watch when performance deficiencies are most likely to occur. Predictions from a correlation of this magnitude, which accounts for 9.7 percent of the variance when adjusted for shrinkage, can lead to an increase in job success rate of 40 to 60 percent (Koelega, 1992; Rosenthal & Rubin, 1982). These findings were interpreted theoretically in light of a resource model of vigilance proposed by Davies & Parasuraman (1982).
