The tendency of some individuals to report changes of physical and mental state after taking pharmacologically inert substances has been investigated experimentally. In a class of healthy medical students, those individuals who reported symptoms and those who did not made significantly different scores on a number of behavioural tests. The likely reactions of the members of a second class (containing none of the previous participants) to dummies were then predicted from their scores on the same tests, some of which were found to be much more efficient predictors than would have been expected by chance. Some implications for further research and for clinical medicine are discussed.
对一些人在服用药理惰性物质后报告身心状态变化的倾向进行了实验研究。在一组健康的医学生中，报告有症状的人和未报告症状的人在多项行为测试中的得分有显著差异。然后根据第二类学生（不包括之前的参与者）在相同测试中的得分，预测他们对安慰剂的可能反应，其中一些测试被发现是比随机预期更有效的预测指标。讨论了对进一步研究和临床医学的一些启示。
