Outline of Final Research Achievements

In this research project, we endowed robots with specific functions and characteristics to investigate how social categorization is understood and emerges based on their psychological criteria, using university students and infants as subjects. The results showed that for university students, mental attribution to robots was categorically influenced by the robots' psychological traits (whether they appeared weak or human-like). Furthermore, experiments with infants suggested that during the Still Face procedure with their mothers, infants categorically changed their responses based on the robot's manner of interaction.

Academic Significance and Societal Importance of the Research Achievements

ヒトは,人種やジェンダー,年齢などによって,社会的カテゴリを創生することがある.しかしながら,人は外見のみならず,その個人が持つ心理的機能により社会的カテゴリを理解し形成することが可能だと考えられる.本研究では,ロボットを用い,ロボットにそれぞれ心理的機能や特徴を付与した,ヒトとインタラクションさせた場合,それらの機能や特徴に基づいてカテゴリを形成することが実証された.本研究は,社会的カテゴリ創発の新しい準拠枠を確認したのみならず,ヒト以外のエージェントに対しても同様のことを行う可能性が示唆されたという意味で,意義深いと考えらる.
