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的感觉输入来产生外部世界的表征。本研究的重点是在产生视觉世界和我们自己的行动意识的感觉输入的后向整合的作用。我们发现，方向信号的视觉意识可以修改postdictively，和postdictive调制的方向外观需要两个方向信号之间的最佳时间间隔。此外，我们还证明，代理感可以追溯性地构建，并且通过后向加工确定代理感是可能独立于通过运动预测确定的。

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.
