Sleep deprivation affects us way more than many more theories have suggested, say, researchers, adding that it impacts peacekeeping - or, the ability to complete a series of steps while not losing one's place, despite potential interruptions. "Our analysis showed that sleep deprivation doubles the odds of making peacekeeping errors and triples the number of lapses in attention, that is surprising," said study researcher Kimberly Fenn from Michigan State University in the United States.

"Sleep-deprived people got to exercise caution in absolutely everything that they are doing, and easily cannot trust that they will not make costly errors. oftentimes - like when behind the wheel of a car - these errors will have tragic consequences," Fenn added.

For the study published in the Journal of Experimental Psychology: General, the researchers recruited 138 individuals to participate in the overnight sleep assessment; 77 stayed awake all night and 61 went home to sleep.

All participants took 2 separate cognitive tasks in the evening: one that measured reaction time to a stimulus; the other measured a participant's ability to take care of their place in a very series of steps without omitting or repeating a step - even after sporadic interruptions.

The participants then repeated both tasks in the morning to visualize however sleep-deprivation affected their performance.

After being interrupted there was a 15 percent error rate in the evening and that we saw that the error rate spiked to about 30 percent for the sleep-deprived group the following morning. The refreshed participants' morning scores were just like the night before.

"There are some tasks individuals will do on auto-pilot which will not be affected by a lack of sleep," Fenn said.

However, sleep deprivation causes widespread deficits across all sides of life.

"Our findings debunk a standard theory that implies that attention is the only cognitive function affected by sleep deprivation," said study researcher Michelle Stepan.

"Some sleep-deprived individuals could be ready to hold it along under routine tasks, like a doctor taking a patient's vitals," Stepan said.
