Effects of sleep deprivation on visual Go/No-Go and motor tracking performance.

<p>Subjects completed a dual task in which a visual Go/No-Go (vGNG) task was performed at the same time as an auditory Go/No-Go (aGNG) task, and a triple task that included aGNG and vGNG tasks, as well as a motor tracking task. The time course of (<b>A</b>) reaction times and (<b>B</b>) errors on the vGNG task is shown during 40 h of sustained wakefulness for dual (white circles) and triple (gray circles) task conditions. (<b>C</b>) The time course for tracking accuracy is shown for the motor tracking task in the triple-task condition. The vertical gray box in each plot shows the usual hours of sleep. In each plot, the mean ± SEM is shown.
