1、在这种情况下，医生可能就会开安慰剂。2 安慰剂可以是糖丸、无害的针剂，或者空的胶囊.尽管安慰剂中没有任何药物成分,但似乎也能使人康复.病人以为这就是药，然后开始好转。这究竟是怎么回事呢？3 安慰剂的研究让人们对人体如何进行自愈有了新的认识.就好像我们每个人体内都有一个医生一样,这位“医生”能治好我们的病，如果我们让他治疗的话。4 但是，我们仍然不清楚安慰剂究竟是如何治病的。有些人说,它能起作用是因为人脑会欺骗自己。这些人说如果能使大脑上当，误以为得到了药物治疗，那么大脑就会像真的得到了药物一样行事，于是身体就会好转。5 另一些人持不同意见。他们认为病人希望身体好转，而安慰剂能促使这种愿望成真。

2、如果病人知道是安慰剂的话，那就没有效果了。这表明人体并没有上当受骗.情况似乎是这样：如果病人以为他们得到了药物治疗,他们就会充满希望。他们感到自己在接受治疗,这使他们更加强烈地希望身体好转，而正是这种希望帮助他们康复。6 安慰剂并不总是有效.这种疗法是否成功在很大程度上似乎取决于病人与医生之间的关系。如果病人非常信任医生，而医生又真心想帮助病人的话，安慰剂就更有可能起作用。所以从某种意义上说，医生是最有效的安慰剂。7 有一项研究可以作为例子来说明医生在促使安慰剂发挥效用的过程中所起的作用.一些溃疡出血的病人被分为两组。第一组病人由一位医生告诉他们用了一种新药,并且相信这种药能够缓解他们的疼痛感

3、。第二组病人由一位护士告诉他们用了一种新药，但是药效如何却不太清楚。结果，第一组中70的病人病情明显好转，而第二组中只有25%的病人情况有了好转。实际上,给这两组病人用的是同样的安慰剂.8 人们已发现安慰剂能在很多不同的病例中发挥作用.它对于晕船、咳嗽、感冒、甚至术后疼痛这样的病症都有帮助。曾经有过一项实验来检验安慰剂是否能帮助老人健康长寿。9 这项实验是在罗马尼亚的150名60岁以上的老人中进行的。他们被分成三组,每组50人。第一组的老人什么也没给.第二组用了安慰剂。第三组用了真药，并被告知这种药对于因年老而出现的疾病有帮助（实际上它根本不是针对老年人的药）.研究人员对三个组的老人的研究持续

4、了很多年。结果显示第一组的状况与那个村庄里老年人一贯的状况没有什么区别；第二组老人（用了安慰剂的）身体要健康得多，死亡率也降低了；第三组老人（用了真药的）与用安慰剂的那组老人结果大致相同。10 使用安慰剂也会导致不良后果。如果病人认为吃药会带来不良反应，那么他们用了安慰剂之后也会有不良反应。这似乎表明你对药物产生何种反应在很大程度上是取决于你的心理而不是你的身体。一些医生仍然认为如果安慰剂有可能导致不良后果，那就不该使用。他们觉得对于安慰剂的了解还不够。11 尽管如此，在别的一些国家，对安慰剂的使用已为人熟知了上百年。在一些非洲国家，部落的医生很早就知道如果病人认为自己会好起来，他们就会好起来

5、。他们采用的很多疗法看似不可能治好病人,但居然行之有效。12 安慰剂的奇效似乎确实表明人的精神力量比我们所想象的要更为强大。有些人认为你可以用精神来治愈自己的疾病。有趣的是甚至那些信誓旦旦认为这是不可能的人也因为用了安慰剂而完全康复了。After-Class Reading如何消除排队的怒火1 如果这个假期你在机场或车站排长队，你是会试着去分析一下排队到底有什么地方使你生气呢还是只会对身边的管理人员生气?2 理查德拉森教授是麻省理工学院的电气工程师，他也讨厌排队。但是他并未因此而怒发冲冠,相反，他决定要研究这个课题。他的第一个研究结果表明,人们恼怒的程度与等待时间的长短并不直接相关，这也验证了

6、美国国家科学基金会的早期研究。他以休斯顿机场的实验为例.在休斯顿机场，乘客们下飞机之后走到行李提取处得用1分钟，然后再等7分钟才能取到行李。对此旅客怨声不断，尤其是那些等候领取行李的旅客，他们眼睁睁地看着那些只带着手提行李的旅客可以马上走出机场，而自己却要等上7分钟。3 机场管理机构决定加长乘客下飞机后的步行距离，这样，走到行李提取处需要6分钟，而不再是快速行走1分钟就能到达。当他们最终来到行李提取处时只需要等待2分钟。那些只带着手提行李的乘客却为此多耽误了5分钟,可是旅客们的抱怨几乎下降为零。4 原因是什么？拉森指出，这一切都与他称之为“社会公正”的现象有关。人们看到别人抄近路,就会觉得自己

7、的等待难以忍受。因此,对于机场来说，让每个人都耽误一下的做法是可取的。5 拉森研究了另一个方面,他观察到：如果不告知人们发生了什么，他们就会变得更加不满.那些知道会耽搁半小时的乘客会比那些莫名其妙等候20分钟的乘客情绪要好一些。6 但是即使知道了我们得等多长时间也不能解决所有问题。我们还要相信有关方面正在采取一切措施来减少耽误的时间。拉森以美国两家相邻的银行为例。一家高度计算机化,为每个顾客服务的时间平均为30秒。另一家自动化程度比较低，为顾客服务需要两倍的时间.但是因为第二家银行的出纳员看起来非常忙碌，顾客们以为它的服务更快，于是许多人把账户转到了这家效率低的银行。最终，第一家银行不得不引进
