| Outline of Final Research Achievements |
While recognition memory performance was similar between children with and without autism spectrum disorder (ASD), children with ASD showed more stable and rigid memory performance than typically developing (TD) children. Correlation between stable memory performance and hippocampal connectivity were weaker in children with ASD than TD.

| Academic Significance and Societal Importance of the Research Achievements |
自閉症児の記憶は、脳内ネットワークを利用せずに局所の機能に依存している可能性があり、文脈や他の情報との結びつきが弱く、個々の情報処理がされている可能性が示唆された。 発達期におけるこのような記憶特性は、 記憶変容が起きにくいという利点にもなりえるが、 自閉症の柔軟性の弱さと関係しているのかもしれない。
