| Outline of Final Research Achievements |
Uncovering the relation between form and meaning of words is important for understanding the nature and evolution of language. Form and meaning of words are associated not only by language-specific arbitrary conventions, but also by an intrinsic link, called sound symbolism, which reflects perceived resemblance between sound and properties of referents. Does one need to be able to hear sound to detect sound symbolism? Here, we show that one does not need to. Deaf-and-Hard-of-Hearing (DHH) participants, even those with profound hearing loss, could judge the sound symbolic match between shapes and words in the same way as hearing participants do, as long as DHH participants could move their tongue freely. This indicates that they detected sound symbolism via inherent resemblance between articulatory movements and shapes. This further suggests that linguistic symbols can emerge through iconic mapping between oral gesture and sensory experience of the world.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の成果は、聴覚障がい者が音象徴性を構音運動と関連づけて認識している可能性を示唆するものである。これは、音象徴が言語の非恣意性に対し、音声が発せられる構音運動の側面から大きく寄与するという可能性を改めて示している。言語を取り巻く諸分野である哲学・生物進化・言語発達・人類学・社会経済学などにおいて、議論されてきた言語の恣意性・非恣意性に対し、実験結果という証拠を提示した点は学術的に意義深いものである。
