| Outline of Final Research Achievements |
Using an approach that compares human social skills with populations with different social phenotypes, this study compared the social phenotypes of children with autism spectrum disorder, who are considered to have difficulties with social interactions, and children with Williams syndrome, which is caused by a partial deletion of chromosome 7, who are considered to have hypersociability. The results of a series of studies revealed that while there were common social response traits that differed between children with autism spectrum disorder and those with Williams syndrome, there were also common items, and the developmental changes in these traits were clarified. We also found the possibility that social phenotypes may change in different social environments. Based on these results, we have also examined the construction of a theory of human social phenotype.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，ヒトの社会表現型が異なる集団を比較する（cross-syndrome）アプローチに基づき，自閉スペクトラム症とウィリアムズ症候群児者における感覚特性，不安特性，社会応答特性，顔認知特性，感情理解発達過程について解明した．一連の研究の結果，これまで両者は社会的認知特性が対極であることが報告されてきているものの，両者は必ずしも対極の関係にあるのではなく，一部に共通する社会的認知特性があることを新たに解明した．これらの知見はヒトの社会性に関する既存の理論の再考を促し，新たな療育などの臨床的への指針を新たに提供する可能性が考えられる．
