| Outline of Final Research Achievements |
Grapheme-color synesthesia is a phenomenon in which viewing a grapheme elicits an additional and consistent sensation of color. First, using a five-language dataset, we show that only an ordinal explanation makes consistent predictions across all five languages, suggesting that the English “A” is red because the first grapheme of a synesthete’s alphabet tends to be associated with red. Second, non-synesthetes tended to associate different graphemes that shared sounds and/or meanings with the same colors, which was analogous to the findings in synesthetes. These results support the view that grapheme-color synesthesia might have its origins in cross-modal association processes that are shared with the general population. Third, we investigated cultural differences between U.S. and Japanese color preferences. Japanese and U.S. color preferences have both similarities and differences. Culturally specific personal experiences during one’s lifetime influence color preferences.
