In the article “A combined field and laboratory design for assessing the impact of night shift work on police officer operational performance” (SLEEP, doi: 10.5665/sleep.2214), we published a report on a combined field and laboratory study investigating the impact of night shift work on police officer operational performance. We compared performance after the last of five consecutive night shifts to performance after three consecutive days off duty. 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 a graph in Figure 1 (panel A) are too small by a factor √2. The corrected graph is 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.
