The odds of signing a false confession were 4.5 times higher for participants who had been awake for 24 hours than for those who had slept eight hours the night before, the findings showed.

Those who indicated a higher level of sleepiness were significantly more likely to sign the false confession, the study revealed.

For the study, 88 participants completed various computer activities and a cognitive test during several laboratory sessions over a week-long period.

The results were striking: 50 percent of sleep-deprived participants signed the false confession, while only 18 percent of rested participants signed it.

Further, sleep deprivation also had significant effect on participants who scored lower on the test related to intelligence. Those participants were much more likely to sign the false confession.

The study will be published in the Proceedings of the National Academy of Sciences.
