7/7 In sum, our findings suggest the integration of visual and tactile signals underlying body ownership remains effective as long as visual info. is available either to generate tactile predictions or to provide direct evidence of touch. However, occluding visual feedback alters perceptual bias.

6/7 These results expand those reported by Chancel & Ehrsson (2021) on how visually-driven tactile predictions affect the point of subjective equality in body ownership: doi.org/10.1016/j.co...

5/7 We also found a bias in hand ownership against the rubber hand that was touched by a robotic arm when its approaching movements were occluded, suggesting that even though vision and touch can be integrated as long as visually-driven predictions occur, there is still a perceptual bias.

4/7 Interestingly, we found that visual occlusion did not affect body ownership sensitivity, which suggests that as long as touch can be visually predicted, the feeling of ownership may arise in the rubber hand illusion.

3/7 Participants had to report in this 2AFC task which rubber hand felt more like their own. Using signal detection analysis, we quantified the sensitivity of their feeling of hand ownership to visuotactile synchrony, and the bias of their feeling of ownership towards the rubber hands.

2/7 Here, we induced the rubber hand illusion with two rubber hands, simultaneously, and varied the degrees of stimulation asynchrony between the real hand and the rubber hands, and visual feedback by occluding the approaching movements of the robotic arms or the touch itself on the real hand.

1/7 The sense of body ownership is crucial for distinguishing between internal and external sources of sensory information, and is the result of the brain's integration of vision, touch, and proprioception. The specific role of sensory predictions in shaping body ownership remains poorly understood.
