Clarifying the general principle of supra-modal postdictive inference of external world

大脑可能通过整合空间和时间上的感觉输入来产生对外部世界的表征。这项研究集中在感觉输入的后向整合在产生对视觉世界和我们自己的行为的意识中的作用。我们发现，方位信号的视觉知觉可以被后向修正，并且方位出现的后向调制需要两个方位信号之间的最佳时间间隔。此外，我们还证明了代理感是可以回溯建构的，并且通过后向加工来确定代理感是可能的，而不是通过运动预测来确定。

The brain possibly generates the representation of external world by integrating sensory inputs in space and time. This study focused on the role of postdictive integration of sensory inputs in generating the awareness of visual worlds and our own actions. We found that the visual awareness of orientation signals can be modified postdictively, and that the postdictive modulation of orientation appearance requires optimal temporal intervals between two orientation signals. Moreover, we also demonstrated that the sense of agency can be constructed retrospectively, and that the determination of the sense of agency by postdictive processing is possible independent of the determination by motor prediction.
