Outline of Final Research Achievements

The present study aimed to clarify the relationships between the encoding and maintenance of fragmented scene information, the temporal characteristics of scene memory, and the process of integrating fragmented information. We employed an experimental paradigm in which fragmented images of a scene were presented sequentially, followed by a recognition task asking participants whether they had seen the images. The results showed that fragmented scene information is more reliably consolidated in memory as encoding time increases, and that such memory consists of components that decay rapidly over time as well as components that remain relatively stable over longer periods. Furthermore, the findings indicated that simply presenting fragmented scene images sequentially does not automatically lead to the reconstruction, maintenance, or integration of the overall scene image in memory.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術・社会的意義は「視野の中心付近でしか詳細な情報を取り込めない」という視覚システムの制約を適切に考慮しつつ，画像の呈示時間を制御できる実験パラダイムを構築した点である。これまでの場面記憶研究では，「場面画像観察時の視線計測」により保持特性が検討されてきたが，注視や視線移動を外的にコントロールできないため，変数を操作する介入的な検討を行うことが困難であった。本研究により連続的な注視を実験的に模擬した呈示方法が明らかになることで，各注視で得られた情報がどれだけ正確に保持されるのかを評価することが可能となり，視線の向きやすさとは独立に記憶のされやすさを製品開発に生かすことができる。
