Outline of Final Research Achievements

This study aimed to empirically investigate which aspects of sound symbolic correspondences exhibit cross-linguistic differences by conducting experiments in multiple languages, and to build hypotheses and lay the groundwork for theoretical explanation based on two aspects: (1) differences rooted in the arbitrary systematicity of phonemic contrasts, and (2) differences based on the embodied iconicity of the phonetic properties of individual language sounds. During the research period, we empirically confirmed that certain linguistic sounds (phonetic features) tend to evoke properties such as shapes, hardness, and maliciousness. We also confirmed that some sound symbolic associations vary across languages. From this, we argued that some of the causes of cross-linguistic differences in sound symbolism lie in the morpho-phonological systematicity of language.

Academic Significance and Societal Importance of the Research Achievements

音象徴はこれまで、身体基盤をもつ有契的現象であり言語普遍的であるとされてきたが、本研究では音象徴が個別言語の恣意的体系性に起因する側面、また音声学的身体基盤に起因しつつも言語間で異なる有契性をもつことを実験的に確認した。認知科学をはじめ音象徴の研究を発展させている諸分野と比べ言語学は実験的手法を必ずしも得意としないが、本研究では実験を中心とした方法をとり、かつ類型論的モデル化という、言語学が他の分野よりも得意とする方法を用いる点に学術的独創性がある。また本研究により、多様な言語での調査に応用できる研究方法が学術共同体に共有され、多くの研究者が継続的に検証し続けていく基礎を提示できたと考える。
