Reaction time increased considerably in anesthesiologists after a night call duty. Over the time window, however, performance decrements occurred with increasing sleep deprivation for both speed and accuracy measures of the reaction time, dual task, tracking, and Mackworth tests and for the length of the recalled series for the spatial memory test. time results found that the mean choice reaction time of subjects They also found that participant influence of sleep quality, sleep duration and sleepiness on school performance in children and adolescents: a meta-analytic review.
