目的：互联网扩大了制造健康恐慌的范围，并增加了接触现代生活各方面对个人健康构成威胁的错误信息的个人对反安慰剂作出反应的风险，如接触新技术。本实验的目的是研究积极期望的传递是否会减少或逆转由这种错误信息形成的消极期望引发的症状。方法：在一项研究中，64名志愿者在两个不连续的阶段评估了他们暴露在风电场声音中的症状，在整个过程中，他们听取了风力涡轮机的声音，其中包含可听和亚可听（次声）成分。参与者被随机分配观看关于次声对健康影响的正面或负面信息，然后进行第一次次声暴露会议。然后，他们被告知的替代信息，并暴露于次声在其第二届会议。结果：接受负面预期的参与者在暴露过程中症状较少，如果他们以前收到了积极的期望次声。此外，参与者给予积极的期望后，较早交付的负面期望表现出安慰剂反应，扭转反安慰剂反应表现在他们的第一次曝光semination.Conclusion：结果表明，访问积极的健康信息框架可能会扭转或稀释负面期望的影响，形成曝光媒体警告的健康风险所带来的新技术，如风力涡轮机。(C)2015 Elsevier Inc.

Objective: The Internet has expanded the scope for creating health scares and increased the risk of nocebo responding in individuals exposed to misinformation about threats to personal health posed by aspects of modem life, such as exposure to new technologies. It was the aim of this experiment to investigate whether the delivery of positive expectations might reduce or reverse symptoms triggered by negative expectations formed from such misinformation.Method: In the context of a study investigating symptoms during exposure to windfarm sound, 64 volunteers assessed their symptomatic experiences during two discrete sessions, throughout which they listened to wind turbine sound containing audible and sub-audible (infrasound) components. Participants were randomly assigned to watch either positive or negative information about the health effects of infrasound prior to their first infrasound exposure session. They were then shown the alternate information and exposed to infrasound during their second session.Results: Participants receiving negative expectations were less symptomatic during exposure if they had previously received positive expectations about infrasound. Further, participants given positive expectations after the earlier delivery of negative expectations exhibited a placebo response, reversing the nocebo response exhibited in their first exposure session.Conclusion: Results suggest accessing positively framed health information may reverse or dilute the effect of negative expectations formed from exposure to media warnings about health risks posed by new technologies, such as wind turbines.
