ABSTRACT
This chapter describes the overarching purpose of the research program to identify a set of individual difference variables that predict vigilance performance, to assemble selection measures to assess the variables, and to validate the measures for use in practical, military personnel-selection settings. Vigilance is the ability to maintain one's focus of attention and remain alert for prolonged periods of time. While the problem of personnel selection for exceptional vigilance and sustained-attention abilities has been researched for years, only limited success has been achieved in predicting individuals' vigilance performance capabilities based on traditional selection tests. More reliable and valid approaches to assessing vigilance aptitudes and capabilities are needed to optimize assignment of personnel and improve overall operational effectiveness in current and future combat environments. It may be possible to identify useful predictor measures from an operator's reactions to performing a short vigilance task that may offer early warning signs of difficulties in coping.
