From: Effects of circadian misalignment on cognition in chronic shift workers
Subjective ratings of sleepiness and performance in chronic shift workers under circadian alignment/misalignment. (A) Subjective sleepiness (KSS) indicated higher levels of sleepiness during circadian misalignment, particularly after 9 h of scheduled wakefulness, as compared to circadian alignment. (B) Subjective ratings of performance (PEERS) did not differ between circadian alignment and misalignment conditions. White and black circles correspond to individual data under circadian alignment and misalignment conditions, respectively. Data correspond to mean ± standard error of the mean, *p < 0.05 (see results for statistics).
