Outline of Research at the Start

「全体が部分を含みつつ部分が全体を含む」ダイナミックな再帰性意識の数学的構造を明らかにし、認知神経科学実験により、再帰性意識の数学的構造に対応する脳内ループ構造を明らかにする。これらにより、再帰的意識を、数理情報と神経活動の構造の間の関係性として明らかにし、再帰性意識の生成メカニズムの理解を目指す。

Outline of Annual Research Achievements

大規模調査で収集したゲシュタルト崩壊心理実験データ解析を行い、知覚変容が生じる割合や、知覚変容の内容を検証した。全体性が失われる場合の知覚のパターンを明らかにすることができた。
さらに、ゲシュタルト崩壊fMRI実験を完了し、データ解析を行なった。ゲシュタルト崩壊している時としていない時で、脳活動に違いが生じることが明らかになった。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

心理実験解析、fMRI解析を予定通り進めることができた。

Strategy for Future Research Activity

2年目の解析結果を取りまとめ、学会や論文で成果報告をする。
