Tornadoes are atmospheric events capable of massive devastation, involving physical destruction and human casualties. Following the 2011 Joplin, MO tornado that claimed the lives of nearly 160 people, the National Weather Service and National Institute of Standards and Technology concluded that better warning systems would have saved lives. This conclusion prompted the creation of impact-based warning (IBW) messages that use explicit language to convey damage threats and potential outcomes. The current study examined the efficacy of impact-based warnings for evoking shelter-seeking intentions in a simulated tornado event. We stratified participants recruited through a crowdsourcing service into 1 of 4 simulated tornado warning conditions, varying with respect to the content and description (IBW) provided. Participants rated their likelihood of immediate shelter-seeking given increasing lead times to the potential tornado strike. Analyses indicated that participants receiving IBW maintained shelter-seeking most across increasing delays. Results suggest viable warning delivery at longer lead times when employing IBW, thereby providing more preparation while bypassing risks of delay-induced inaction.

在标准天气和基于影响的天气警报中,龙卷风避难所意图的时间折扣:众包实验。

龙卷风是能够造成巨大破坏的大气事件,涉及物理破坏和人员伤亡。在2011年密苏里州乔普林龙卷风夺走了近160人的生命之后,美国国家气象局和美国国家标准与技术研究院得出的结论是,更好的预警系统将挽救生命。该结论促使创建了基于影响的警告(IBW)消息,该消息使用明确的语言来传达损害威胁和潜在结果。当前的研究检查了基于影响的警告在模拟龙卷风事件中激发寻求避难所意图的功效。我们将通过众包服务招募的参与者分为4种模拟龙卷风警告条件中的1种,但条件与所提供的内容和描述(IBW)不同。参加者评估了由于潜在龙卷风罢工的提前期增加而他们立即寻求避难所的可能性。分析表明,接受IBW的参与者在延误不断增加的情况下,大部分都是寻求避难所。结果表明,采用IBW时,可以在更长的交货时间内提供可行的警告,从而提供更多的准备,同时避免因延迟而导致不作为的风险。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。
