The impact of appearance and postural congruency on sense of ownership and agency in virtual hand illusion
The virtual hand illusion is a classical paradigm to investigate the sense of ownership.With synchronous visual-tactile,proprioceptive and motor information,participants illusorily experience that the virtual hand as their real hand,and feel that they can control it.In this work,the virtual hand illusion was used to investigate the effect of postural and appearance congruency on the explicit and implicit sense of ownership and agency.The results showed that,in both explicit and implicit measurements,postural congruency affected the sense of ownership,but did not affect the sense of agency;Appearance congruen-cy affected both the sense of ownership and sense of agency,while detailed results showed difference.The results suggest that even explicit and implicit ownership and agency are sometimes affected by the same manipulations,their cognitive mechanisms are different.
