From: Daily circadian misalignment impairs human cognitive performance task-dependently
Daily dynamics of cognitive performance under circadian alignment/misalignment. (A) Sustained attention (PVT 10% slowest reaction times) worsened following acute circadian misalignment (T1), which lasted up to two days subsequent to it (T2 and T3). See also Figure S1. (B) Cognitive throughput (ADD number of correct responses/min) performance improved only under circadian alignment for test days 2–4 (T2-T4). (C) Information processing (number of correct DSST responses/min) performance improved only under circadian alignment during test days 3–4 (T3-T4). (D) Visual-motor performance (number of TKT losses) did not significantly differ between circadian alignment/misalignment. Green (open symbols) and red (closed symbols) lines correspond to, respectively, circadian alignment and misalignment conditions. Data correspond to mean ± standard error of the mean (n = 13), *p < 0.05 (see results for statistics).
