Outline of Final Research Achievements

This study conducted a meta-analysis by collecting multiple previous studies reporting survey results about evacuation from the areas affected by water and tsunami disasters. As a result of the meta-analysis, we found three major factors related to evacuation psychology in the event of a disaster and accompanying factors that promote or suppress each major factor. Based on these factors, an evacuation decision-making model was constructed. In addition, through the experiment conducted in this study, it has become clear that it is possible to arouse more sense of urgency to the listeners by announcing an evacuation order issued by the local government, which sounds with the tone of command and short simple sentence structures. Such way of evacuation order announcement can be considered to promote the awareness of danger which is one of the major factors in the evacuation decision-making model constructed in this study.

Academic Significance and Societal Importance of the Research Achievements

本研究は、これまであまり取り上げられてこなかった避難の呼びかけの言語学的構成要素に焦点を当て、避難の意思決定モデルという心理学的な領域への影響を考察した点で、意義があると考える。ここで言う言語学的構成要素とは、「避難せよ」などの命令調と文章の構成が主語と述語それぞれ１つずつからなる単文のことである。これらの要素が聞き手に危機感を喚起し、避難の意思決定の重要な要素である「危険認知」の促進要因になることが示唆された。
