此前已经证实安慰剂效应可作用于免疫系统。但这项研究可能首次展示这种效应以一种不同的方式(即一种意志行为)发挥作用。安慰剂效应的权威专家、意大利神经学家法布里齐奥·贝内代蒂(Fabrizio Benedetti)表示:“据我们目前所知,免疫系统中的安慰剂反应可归因于无意识的经典条件反射。”在贝内代蒂的实验中,植入受试者思维中的心理暗示直接引起了生理反应,就像晚餐铃引发狗的唾液腺分泌一样。(在一项研究中,健康的志愿者得到这样一种安慰剂:一种心理暗示,让他们以为自己所经受的任何疼痛其实都有益于身体健康。结果,他们体内产生的天然镇痛剂水平有所提高。)贝内代蒂指出:“尚无证据表明预期也能发挥作用。”现在,兰格计划进一步分析受试者的唾液,看其中是否确实存在鼻病毒,而不只是偏高的IgA抗体水平。
The implications of the open placebo — that is, we know the sugar pill is just a sugar pill, but it still works as medicine — are tantalizing. If placebo effects can be harnessed without deception, it would remove many of the ethical issues that surround placebo work. In a study published in the journal Plos One in 2010, Ted Kaptchuk, a professor of medicine at Harvard Medical School, and his colleagues administered a placebo labeled “placebo” to a test group of patients suffering from irritable bowel syndrome. Their symptoms declined significantly as compared with a no-treatment control group. “At some level everybody realizes they themselves are the placebo,” Langer says.
