In this set of materials both the writer and lecturer cover the issue of placebo effect. Regarding the issue, the lecturer contradicts the reading passage's claim that placebo effect may not be real and that placebos are generally ineffective as a medical treatment.
First, the lecturer argues that placebos are effective medicines. This is because placebos are not only the mind over, it is real action. (wrong expressions.)+(need a little more detail) This opposes the reading passage's assertion that placebo effects are not real treatment.
Second, the speaker insists that actual physical changes occur by placebos. To be specific, natural pain killer decreases patient's pain. Moreover, patients who drink salt water as pain killer can reduce their pains. This contradicts the reading passage's claim that placebos just make patient's condition to get better. ?? reading은 효과없다 아닌가요?
Third, the professor maintains that without habit change at all even without any habit change, placebos make patients better. For example, Parkinson’s disease patient does not change their life style such as diet, exercise. life style when getting treated by placebo medicines. However, their shaking hands are better by their symptoms like shaking hands show improvement due to placebo effect. This cast doubts on the reading passage's explanation that patient's illnesses get better by changing their life style not placebo effect. |
