Figure 3.

Number of attentional lapses on the psychomotor vigilance test (PVT) and positive and negative affect on the PANAS across the laboratory study. The PVT results are shown in the top panel; the positive affect (open circles) and negative affect (solid circles) are shown in the bottom panel. Each graph shows the means on each measure for each group (TSD or WRC); error bars represent standard error of the mean. On the top of each graph, black bars indicate scheduled sleep, gray bars indicate sleep for the WRC condition only, and the stars represent the two administrations of the AISM.
