| Outline of Final Research Achievements |
We tested the social communication abilities between child and dogs, such as reading social cues (eye sight or hand sign) and the prosocial behavior between different animals (the ability to share resources with others). We found that even infants which do not pass the mirror test (do not yet show self recognition) can still perform the prosocial behavior (share food or toys with the dog instead of occupy the food or toy by themselves) toward the dogs. On the other hand, only dogs which show positive oxytocin loop (star longer time to the child's face) perform the prosocial behavior. This is the first study testing the prosocial behavior between different animal species, and can give us insights to the evolution background of prosocial behavior, which is very important in all the social animal societies.

| Academic Significance and Societal Importance of the Research Achievements |
ともに暮らす動物の存在が子供の知覚、認知、言語の発達を促すことは数多くの先行研究から示唆されている。しかしながら、子どもと動物の間のどのようなインタラクションがしているのかはほとんどわかっていない。
この研究は異種間において向社会的行動が生じることを示した初めてのもので、伴侶動物としての長い歴史の過程でイヌがこの能力を獲得してきたことを示唆します。これまで社会的相互作用の進化については主に類人猿とヒトを比較することで検討されてきましたが、本研究はこの問題の解明にイヌ科動物の社会行動の比較調査が役立つことを示したものであり、進化学に新たなツールを提供するものと考えます。
