| Outline of Final Research Achievements |
To better understand evolutionary origin of crossmodal correspondences, we examined if chimpanzees have such correspondences. Specifically we focuses on crossmodal correspondence between sound pitch and brightness and one between sound pitch and spatial position. Previous studies have shown that we human have to types of biases supporting crossmodal correspondences between sound p@itch and brightness. One is called attention bias which guide participants attention to corresponding brightness upon hearing a sound. The other is called perceptual bias, which shift subjective experience of brightness toward the corresponding brightness upon hearing a sound. Our research showed that chimpanzees have both biases similar to human and also have correspondences between sound pitch and spatial position.

本研究は、ラベル生成・理解、概念メタファーの進化的基盤として感覚間一致に着目し、比較認知科学的なアプローチをおこなうことで、言語進化の研究に新たな道筋をつけた最先端研究といえる。こうした、新たなアプローチを施すことにより、感覚間一致に関して、ヒトとチンパンジーをはじめとするその他の種の間の相違点をあきらかにすることで、ヒトの言語の進化的基盤に対し、新たな知見を提供でき、認知科学、進化心理学、比較認知科学の研究分野に大きなインパクトを与えると期待される。
