THE EFFECT OF RISE AND DECAY TIME ON VIGILANCE FOR WEAK AUDITORY AND CUTANEOUS STIMULI
Abstract
Observers were asked to respond to the presence of infrequent broad band auditory or electrical cutaneous stimuli. Fast and slow rates of stimulus onset and decay were utilized. Errors of omission were significant and more numerous for cutaneous signals and increased with time on task. No decremental tendency was found for auditory stimuli. Differential effects due to rate of stimulus onset and decay were not significant. An explanation of the difference due to modality was suggested in terms of a filter or combined arousal-filter theory. (Author)
