今天结束了生理心理篇,依然惨不忍睹
So, you see, physical illness can have psychologicalcauses. Now, we just have time to introduce another interesting example of the interactionbetween the mind and the body—placebos. Placebos,--maybe you’ve heardthem called sugar pills, are harmless substances--not always sugar—that are used routinely on groups sickpeople in it’s experiments.These experimentals testeffectiveness offor new drugs: One group is given the new drug, the other groupis given a placebo, and the results are through measured. As youmight guess, some of the people who receive the new drug get better. Surprisingly,however, some of the placebo group also getbetter. Why? Well, it’s an interesting question,one which doctors can’t quite answer. Some of the group may have gotten better on their own,without any treatment at all, but research hasshown that the very act of taking a medication that you think willmake you better. Often does make you feel better. Haveyou ever taken an aspirinand felt better in five minutes? Aspirine doesn’t work that fast,does it? Basically, if you believe you will get better--sometimes you do. The historyof how doctors and healershave used themind--body to connectionto cure people is long and interesting--but I see that it’stime to close. So, I’ll have to cover this in the next class. You'll have to holdyour questions on this topic till then.... Before you go, I have some handoutsfor you concerning the midterm exams next week. |
