Researchers have studied the placebo(安慰剂) effects for many years.But there are still many unanswered questions.Why is a placebo effective?Mostly,researchers have looked at the placebo effects on physical health.However,a research team in Sweden has produced some interesting findings about the emotional effects of placebos.
The team performed a series of experiments.First the researchers showed a group of people unpleasant pictures,like pictures of dead bodies.The people rated(划分等级) how they felt after seeing the pictures.They gave the highest number to the pictures that gave them the worst feelings.The researchers then gave the people a calming drug.They told the people that the calming drug would decrease the unpleasant feelings from the pictures.When the team showed the pictures again,the people said that they felt much calmer.
The following day,the researchers gave the people unpleasant pictures to look at again.Then,they gave them drugs.However,this time they gave them a placebo instead of the calming drug.The placebo was nothing but salt and water.But the people did not know this.
After taking the placebo,the people's ratings still changed.Their unpleasant feelings decreased by almost 30%.It seemed that taking the placebo made them feel calmer.In the experiment,the scientists also used special equipment to look at their brains.The results showed that the brains'emotional centers were calmer after the people took the placebo.
Dr Predrag Petrovic managed the experiment.He said,"The placebo changes what we expect.When we expect that something unpleasant should become less unpleasant,it really does."
