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官输入来产生外部世界的表征。本研究的重点是感官输入的后置整合在产生视觉世界和我们自己的行为意识中的作用。研究发现，定位信号的视觉感知可以后置性地改变，并且定位外观的后置调制需要两个定位信号之间的最佳时间间隔。此外，我们还证明了代理感可以回顾性地构建，并且通过后置处理确定代理感可能独立于运动预测确定。

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.
