Short Sleepers and Error Monitoring

Abstract (Summary)

The detrimental effects of total sleep deprivation on cognitive function are well documented yet shortened sleep is more prevalent and less understood. Evidence suggests that even modest sleep restriction can result in diminished cognitive function. Error monitoring, a cognitive process relied on to minimize errors, is sensitive to sleep restriction. The current study evaluated error monitoring in short sleepers (i.e. < 7hrs) and mid-range sleepers (i.e. 7 – 9). Fifty-four participants completed one week of sleep/wake assessment via a wrist-worn actigraphy device and sleep diary. An arrow version of the flanker task was used to examine behavioral and electrophysiological indices of error monitoring including accuracy, error awareness (EA), error-related negativity (ERN) and error positivity (Pe). Short sleepers displayed a lower EA rate in comparison to mid-range sleepers, on low conflict trials. Both groups performed with similar accuracy and response times. Because an ERN was not reliable, Pe was not further evaluated. The present study puts forth evidence that shortened sleep can impair subjective EA.
