Study Shows That Your Belief Of Having Slept Well Improves Your Brain Performance

This study has reflected human’s mental power – our faith and belief can actually change the way we act. In the experiment, participants were lied about their sleep quality. Some were told that they had above average REM sleep while others were told that they had below average REM sleep. After that, they had to take a test that measures “auditory attention and speed of processing, skills most affected by sleep deprivation”. The former ones performed better on the test, while the latter ones performed worse.
