Nostalgia is a mixture of positive and negative emotions and is defined as ‘a sentimental longing for one’s past’. Previous psychological research has shown that nostalgia has positive psychological functions. The aim of this study was to determine the effect of contour thinness on nostalgia in university students, who spend a lot of time listening while doing something else and are considered to be less affected by the experimental situation. The results of a psychological experiment using cross-modal stimuli consisting of black and white line drawings and piano practice pieces showed that contour thinness induced nostalgia. In addition, it has been suggested that the nostalgia induced by thin contours, as if drawn with a fine-tipped pen, may have a positive impact on the temporal outlook of the future. These results can be used for scientifically based nostalgia marketing.
