校歌の歌詞から感じる「なつかしさ」の生起モデルの構築

抄録

Many people have experienced that even long after their graduation, their school songs can still evoke nostalgia of their old school days. In this study, we proposed a psychological model of the generation mechanism underlying the school-song-evoked nostalgic feelings. Firstly, we extracted the terms characteristic of school songs from the lyrics of 156 Japanese school songs. Then, we investigated how the number of years that had elapsed since graduation influenced the degrees of school-song-evoked nostalgic feelings through questionnaires. Finally, we conducted an experiment in which the participants were asked to rate the “school-songness” of the lyrics of four existing school songs as well as an “average school song” which we made using the terms extracted at the first stage of the study. The results show that the “average school song” ranks highest, which implies the properness of our model.
