Outline of Final Research Achievements

The external world has statistical properties in terms of time and space. By using these statistical properties, efficient information processing becomes possible. This study focused on (1) the modeling of the learning process of spatial arrangements (contextual cueing effect) and (2) the examination of the coordinate system used in the spatio-temporal integration (serial dependence). We proposed a model that extracts global features from images and learns the relationship with the position of the target to be searched for. The model was successful to reproducing the learning speed difference between letter arrangement and natural image. The psychophysical experiment demonstrated that serial dependence is carried out based on retinal position.

Academic Significance and Societal Importance of the Research Achievements

空間配置の学習モデルは文字配置を扱うものは提案されていたが、自然光景に対する学習を扱うことのできるモデルはこれまで提案されていなかった。自然光景に対する学習過程をモデル化することは、光景の情報処理と効率的な行動の関係を理解することにつながる。また、どのような情報を学習し、行動に利用しているのかを明らかにすることは、製品デザイン等の設計指針に関する基礎的な知見を提供する。
