テレビやラジオ,屋外拡声放送等による災害避難勧告アナウンスに対して住民が避難行動を起こさない問題が浮き彫りになった.その原因のひとつに,「正常性バイアス」と言われる心の動きがあると指摘されている.我々は従来から,正常性バイアスを打破し「思わず逃げたくなる」新しい避難喚起アナウンスの構築を目指して研究を行ってきた.本研究では,既存の避難勧告アナウンスに視聴覚刺激を付加提示することにより切迫感が向上すると想定し,背景画像や背景音を付加した際の印象効果を検討した.実験の結果,背景音の付加効果は背景画像の場合より高く,背景音と背景画像を組み合わせて提示した場合の効果が最も高かった.また,各音声内容と関連のある背景画像や背景音を付加した場合の行動喚起因子の評価が高く,切迫感を向上し得ることが示唆された. |

It is reported that emergency-related damage has been increased because residents who were in danger frequently made overly-optimistic judgments leading to serious delay in their evacuation times even in the face of natural disasters such as earthquakes, tsunamis, and landslides. A human cognitive tendency called "normalcy bias" is considered a factor in preventing residents from evacuating when hearing emergency announcements via outdoor mass-notification sound broadcasting. We have been conducting research aimed at overcoming normalcy bias and constructing new evacuation announcements "promoting unconscious evacuation behavior". In this study, we hypothesized that addition of background sounds and images to emergency warning announcements could increase a sense of urgency, inducing evacuation behavior. We therefore investigated differences in subjective impressions of the announcements with and without background sounds and images. Results showed that factor scores for behavior with additional background sounds and images were highly effective when the additional sounds and images related to each type of emergency of the warning announcement. The effect from addition of background sounds is greater than that from images, and when these were combined, the effect was the strongest. |
