Outline of Research at the Start

自閉スペクトラム症(自閉症)の特徴である限局的興味や繰り返し行動は、発達期の学習と記憶の非柔軟性によって増強される可能性がある。本研究では、自閉症児と健常児(定型発達児)を対象に、絵と名前のペアの学習(直後再認)と想起(遅延再認)検査を実施し、直後と遅延の再認成績の一致/不一致から、記憶の安定性、記憶変容の程度を検出する。加えて、機能的磁気共鳴脳画像法(MRI)によって安静時における脳血流反応を測定し、全脳部位間の機能的結合を同定する。その結合の強さと記憶変容の関係を健常児と比較することで、自閉症児の記憶の非柔軟性の脳内メカニズムを明らかにする。

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。
