Abstract : Research was performed to determine the effect of an external audio signal on visual monitoring performance and any associated changes in physiological parameters of the subjects. The number of correct detections, the number of commissive errors, skin temperature, and skin resistance were recorded throughout the experiment. A two way nested analysis of variance correlated application of the audio signal to vigilance decrement. Multiple correlation analyses of the data indicated a high degree of complex interaction between the physiological parameters measured and the vigilance detection decrement. (Author)
