閱讀測驗 46-50Feeling drowsy and tired after a bad night’s sleep? Here comes the good news: simply being toldyou’ve slept well could help perk you up.Most people are probably aware of the placebo effect. Taking a pill of any kind can make one feelbetter, even if that pill has no active ingredients. The good news is that the placebo effect is not onlylimited to gel capsules you take when you are ill. Nowadays, it’s possible to get placebo exercise andeven placebo sleep.The phenomenon, called placebo sleep, involves telling people that they have got a good sleep evenwhen they haven’t. People who were told they got a good night’s sleep function better at work than thosewho thought they slept poorly.Scientists at Pennsylvania State University in the U.S. conducted a study in which researchparticipants were told that a new technology, which doesn’t actually exist, could measure their sleepquality from the night before. They were connected to a machine monitoring brainwave frequency andshown piles of spreadsheets and formulas. Then some were informed that their deep sleep or rapid eyemovement (REM) sleep had been above average the night before, a sign they were mentally alert. Otherswere told their REM sleep from the night before had been below average. Research participants in bothgroups were then informed of the importance of sleep quality to cognitive functioning.Surprisingly, those who thought they had a good night’s sleep concentrated better and functionedwell at work. The effect of placebo sleep has to do with a participant’s mindset regarding his or her sleepquality. While placebos are widely used in drug testing, the scientists say their experimental resultssuggest the importance of perception and the brain’s role in health.
