From: Effects of circadian misalignment on cognition in chronic shift workers
Association of sleep efficiency with cognitive performance in chronic shift workers. (A) Sleep efficiency was lower during circadian misalignment, as compared to when the same individuals were under circadian alignment. Correlations between sleep efficiency levels (x-axis: difference of sleep efficiency between circadian misalignment and alignment conditions) and sustained attention (y-axis: (B) PVT slowest reaction times, (C) PVT lapses), (D) information processing (y-axis: DSST ratio of number of correct responses/minute), and (E) visual-motor performance (y-axis: TKT number of losses). X-axis and Y-axis correspond to the difference between circadian misalignment and alignment conditions. For panel A, 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).
