Prior research has not adequately identified variations in nostalgia valence across cultures. In my study, I will recruit participants from collectivistic and individualistic cultures, create a baseline condition, and follow it with an experimental condition in which they write about a nostalgia experience, and rate their emotions along two unipolar valence dimensions using the Evaluative Space Model. My expected findings include a higher negative valence when experiencing nostalgia in collectivistic cultures compared to individualistic cultures.
