Abstract
This study investigated the relationship between individual performance on a visual vigilance task and an auditory vigilance task. Each of 40 male college subjects participated in two 35 minute test trials, one visual and one auditory. In each 35-minute trial five randomly spaced vigilance signals were presented. Various indices of correlation computed from the data obtained in this study show no relationship between auditory and visual vigilance performance. The percentage of signals detected is probably affected by sensory acuity factors; however, the data of this study did not provide a test of this hypothesis. Other studies should be conducted, comparing the decrement in detection efficiency rather than the percentage of total signals detected. This suggested measure should be less sensitive to sensory acuity components of vigilance than the over-all percentage detection measure used in this study.Keywords
