| Research Abstract |
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.
