| P value | < 0.0001 | < 0.0001 |
| PVT, fastest 10% RT | ||
| df | 1,2665 | 1,328 |
| F value | 40.88 | 24.14 |
| P value | < 0.0001 | < 0.0001 |
| PVT Lapse | ||

In the left column, the entire forced desynchrony (FD) condition is compared with the baseline (BL) condition, whereas, in the right column, only those FD days that began at a similar circadian phase as the BL days were included. ADD refers to Addition Calculation Test; PVT, Psychomotor Vigilance Task; RT, Reaction Time; df, degrees of freedom.
