This project will improve understanding of the kinds of information people seek when facing a tornado threat, how the information they obtain affects their risk perceptions, and the way that their risk perceptions affect their protective actions. This project will have a number of positive impacts to the broader society. Experimental materials (including software) will be made publicly available to a range of researchers, including those from under-represented groups, so that other studies may augment and extend the approach developed here. The project also includes extensive outreach to professional broadcast meteorologists and to organizations such as the National Weather Service, Federal Emergency Management Agency, and state and local government emergency management agencies in order to inform how weather-related risks are communicated to the public. This project will introduce two major innovations into research on protective action decision making (here, in the context of tornado-related risk). First, in a departure from conventional, exclusively survey-based studies, human-in-the-loop experiments incorporating computer-based dynamic decision making exercises will be used. Alternative protective actions (such as seeking additional information, shelter in-place, or evacuating) will be investigated by examining detailed logs of participant interaction with the computer-based simulation. Second, this project will overcome a limitation of previous studies that have focused solely on individuals by comparing decision processes by individual with those of pairs (here, married couples). This work is therefore expected to reveal how interpersonal ties help determine protective actions in households.

该项目将提高人们面对龙卷风威胁时人们寻求的信息的理解，他们获得的信息如何影响他们的风险看法以及风险看法影响其保护行为的方式。该项目将对更广泛的社会产生许多积极影响。实验材料（包括软件）将公开向一系列研究人员公开使用，包括来自代表性不足的群体的研究人员，以便其他研究可以增加此处开发的方法。该项目还包括向专业广播气象学家以及国家气象局，联邦紧急管理局以及州和地方政府紧急管理机构等组织进行广泛的宣传，以告知与天气相关的风险如何传达给公众。该项目将向保护行动决策的研究引入两项主要创新（在与龙卷风相关的风险的背景下）。首先，在与常规的，仅基于调查的研究的背景下，将使用融合基于计算机的动态决策练习的人类在环境实验中。将通过检查与基于计算机的模拟的参与者互动的详细日志来研究替代性保护行动（例如寻求其他信息，住所或撤离）。其次，该项目将克服对以前的研究的局限性，这些研究仅通过比较个人的决策过程与成对的决策过程（这里是已婚夫妇）。因此，这项工作有望揭示人际联系如何有助于确定家庭中的保护行动。
