Driving simulator
The SDLP measured by the simulator was significantly increased (9.97 cm, p < .001) after a night of sleep deprivation compared to the morning assessment after a well-rested night. The SD-speed for the simulator increased significantly after a night of sleep deprivation compared to the assessments on the well-rested morning, while the mean speed was not. Like the GRIDT, subjects rate a decrement in their driving performance and motivation, and an increase in effort scores after a night of sleep deprivation compared to the well-rested morning.
