Valence sound symbolism across language families: a comparison between Japanese and German

Abstract Vowels are associated with valence, so that words containing /i/ (as in English meet ) compared with /o/ (as in French rose ) are typically judged to match positively valenced persons and objects. As yet, valence sound symbolism has been mainly observed for Indo-European languages. The present research extends this to a comparison of Japanese-speaking and German-speaking participants. Participants invented pseudo-words as names for faces with different emotional expressions (happy vs. neutral vs. sad vs. angry). For both Japanese-speaking and German-speaking participants, vowel usage depended on emotional valence. The vowel I was used more for positive (vs. other) expressions, whereas O and U were used less for positive (vs. other) expressions. A was associated with positive emotional valence for Japanese-speaking but not German-speaking participants. In sum, emotional valence associations of I (vs. rounded vowels) were similar in German and Japanese, suggesting that sound symbolism for emotional valence is not language specific.
