Sleep-deprived people thought that they were doing well in reaction time tests conducted by the researchers. Their test results showed that people who lacked sleep do badly on the tests. The results didn’t surprise them, but the lack of awareness of their condition did.

In one of the experiments, results showed that men rated photos of the least attractive models as being more attractive. The effect was not seen amongst women. In a previous experiment, results showed that men think women want to have sex with them.

People who had been awake for 18 hours straight scored higher on the standard tests of global paranoia. People lacking sleep rated higher on depersonalization or feeling separated from one’s thoughts, reality or body.

People who lack sleep should not be gambling, according to one study conducted by researchers from the University of Pittsburgh. When sleep-deprived people were expecting to lose money, their brain showed less activity in the regions that are connected with the mind’s reward system.
