Abstract

Over the past fifty years, there has been ample research in sustained attention, or vigilance, in the area of psychology and human factors. Although it was often questioned whether the large volume of research had a palpable impact on real world situations, various vigilance tasks and findings from the laboratory have been applied to the work world including transportation, military operation, inspection, safety management, and neuropsychological diagnosis and rehabilitation. Due to the increasing tendency of automation in industry, it is expected that there would be more and more dependence on human monitoring performance rather than on the ability of operating the system itself, which would in turn lead to the need for more effort to minimize the vigilance problem. The present study was aimed to review how the work in the laboratory was implemented to the real life problems and to discuss what needs to be done to bridge the gap between the two seemingly separate, but in fact quite interdependent worlds. A brief review of the neurophysiological basis of sustained attention, tools and tasks for measuring individual differences in sustained attention, and the psychological factors influencing vigilance performance was provided as well to understand the nature of vigilance problem.
