Evaluating and modeling human performance on even simple tasks requires a great deal of attention to millisecond-level cognitive and perceptual-motor operations. Modeling human performance in a task often requires that special care be taken to understand how these millisecond level operations are interleaved and how they evolve during the execution of the(More)
Research on sleep loss and vigilance both focus on declines in cognitive performance, but theoretical accounts have developed largely in parallel in these two areas. In addition, computational instantiations of theoretical accounts are rare. The current work uses computational modeling to explore whether the same mechanisms can account for the effects of(More)
Visual working memory (VWM) is a construct hypothesized to store a small amount of accurate perceptual information that can be brought to bear on a task. Much research concerns the construct's capacity and the precision of the information stored. Two prominent theories of VWM representation have emerged: slot-based and continuous-resource mechanisms.
