Consistency of individual differences in human vigilance performance: An abilities classification analysis

Abstract

E. A. Fleishman (see PA, Vol 41:3743; 50:204; and 55:11342) has pointed out that more effective use of human performance data could be made if performance on different tasks were studied within an organizing task classification system. This approach was applied to an investigation of the consistency of individual performances on different visual monitoring tasks, which were classified on the basis of the abilities taxonomy developed as requiring 1 of 2 abilities for efficient performance: "perceptual speed" or "flexibility of closure." Three groups of experienced monitors (a total of 30 17-26 yr old males) were tested on pairs of tasks classified either similarly or differently in this taxonomy. Individual differences were highly consistent for performances on tasks requiring the same ability, despite dissimilarities in displays and significantly less so for tasks classified differently. Results provide further support of the importance of the abilities classification approach for the evaluation of performances on different monitoring tasks.
