In the article “The efficacy of a restart break for recycling with optimal performance depends critically on circadian timing” (SLEEP, doi:10.5665/SLEEP.1128), we published a report on a laboratory study investigating the efficacy of a restart break for recycling with optimal performance, comparing simulated night versus day shift work. We used high-fidelity driving simulators to test driving performance, which was quantified in terms of lane deviation (standard deviation of lateral lane position). Due to an error in the software used to calculate lane deviation, the values we plotted in graphs in Figure 2 (top right) and Figure 3 (top right) are too small by a factor √2. The corrected graphs are provided below. The statistical analyses and inferences in the paper are not affected. The authors thank Dr. Dario Salvucci for pointing out the miscalculation, and they regret the error.
