night two and 3h on mornings three and four. Cognitive testing was performed every 3h during scheduled wakefulness. Executive function and cognitive processing speed were tested with a Stroop Color Word task and selective visual attention was tested with a conjunction visual search task. Stability of individual differences in cognitive function were quantified by intra-class correlation coefficients (ICC) derived from linear mixed effects models with subject as a random factor and visit and battery number as fixed factors. Results:  During combined sleep restriction and circadian misalignment, cognitive processing speed (median reaction times for correct responses to congruent, neutral, and incongruent stimuli), executive function (inhibitory control), and visual selective attention (cognitive throughput) were significantly impaired (p
