Outline of Final Research Achievements

We have found a possibility that procrastination could occur if the value of the option accompanied with cost is estimated to be lower than the value of the option to avoid such an action due to inaccurate value approximation when dimension-reduced successor representation (a way of representing states by future stays at their successor states) is used. We also conducted research combining questionnaire and experiment on execution of tasks with costs and learning profiles, and also investigated the delay load preference in seconds.

Academic Significance and Societal Importance of the Research Achievements

負荷の回避・先延ばしがいかなるメカニズムで生じうるかについて、後継表現および状態表現における次元削減との関連を見出した点、また、負荷のかかる行動の回避や評価などと価値学習の様態の関連を調べた点などに意義があると考えられる。また、認知制御の先延ばし行動を明らかにすることで、日常生活における問題行動のしくみを理解し、予防方法を検討することが可能となると考えられる。
