Vigilance or sustained attention is a critical aspect of many jobs including air-traffic control, medical screening/monitoring, and detection of illicit radioactive material at seaports and border crossings. An extensive review by Reinerman (2006) concluded that traditional approaches to personnel selection encompassing sensory acuity, aptitude, sex, age, and personality measures for tasks requiring sustained attention have been ineffective. The present study utilized the methodology from Reinerman et al. (2006), which attacked the selection issue 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 sensory vigilance task. Two predictors of interest were cerebral blood flow velocity, measured via transcranial Doppler ultrasonography (Warm and Parasuraman, 2007) and subjective state, as indexed by the Dundee Stress State Questionnaire (Matthews et al; 2002). The present vigilance task was a letter transformation working-memory task and was composed of four consecutive 9-min periods. Such cognitive vigilance tasks require different information-processing components and responses than those of sensory tasks. The aim for the present study was to generalize the findings of Reinerman et al. (2006) to that of cognitive vigilance. Multiple regression (R = .577) 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 28.1 percent of the variance when adjusted for shrinkage, can lead to an increase in job success rate of 40 to 60 percent (Rosenthal and Rubin, 1982). These findings were interpreted theoretically in light of a resource-workload model of vigilance (Davies and Parasuraman, 1982).
