| Outline of Final Research Achievements |
The purpose of this study was to clarify changes in time perception in schizophrenia. First, we focused on dopaminergic changes related to psychological time in neurological disorders such as schizophrenia and Tourette's syndrome, and found the changes in time perception in these disorders. In addition to this, based on a hypothesis that patients with schizophrenia are associated with an abnormal weighting of prior in perceptual inference, we conducted behavioral experiments and found changes in the strategies of perceptual inference in patients with schizophrenia.

| Academic Significance and Societal Importance of the Research Achievements |
精神疾患における知覚の変化については古くから報告されているものの未だ不明な点が多く，治療標的は未だ不明な点が多い．本研究により，統合失調症の時間知覚における認知的方略の変化を明らかにしたことは精神疾患症状の発生メカニズムの解明に寄与するものであると考える．
