Abstract
Objective To observe the effect of attention after sleep deprivation in healthy volunteers.Methods10 healthy young male volunteers were exposed to continuous sleep deprivation for 32 h.Continuous performance task(CPT) and Stroop tests were performed 4 times to the volunteers at 17 h and 32 h before and after sleep deprivation.Results In CPT and Stroop test,the total reaction time and error rate were elevated significantly after sleep deprivation(all P0.05),and the average reaction time and error rate of the second test were elevated significantly compared with the first test after sleep deprivation(all P0.05).Conclusion The attention is decreased after sleep deprivation significantly in healthy volunteers,and the longer sleep deprivation time,the more obvious.
