Abstract: The vigilance decrement is a central topic in human factors research but has not yet given way to a clear theoretical understanding. Resource depletion theory, the most popular account of the effect, provides at best a qualitative and vague model of vigilance performance. More precise predictions are necessary for strong theory testing. The current study developed a computational account of the vigilance decrement, building on a quantitative, dynamic cognitive model of signal detection. The model reproduces supposed hallmark patterns of resource depletion, without incorporating a depletion process. Results suggest that a stronger emphasis on computational modeling can provide more concrete theories of the vigilance decrement and help resolve lingering points of disagreement in theories of sustained attention.
