Abstract
The sense of body ownership has been studied using full-body illusion (FBI). It has been shown that the FBI is less likely to induce a sense of body ownership in people with depersonalization tendencies who have difficulty feeling a sense of body ownership when they are made to view a fake body in VR as their own body in a top-down manner. In a case study of depersonalization, it has been suggested that the top-down cognition of the self-body as a negative state decreases the sense of body ownership, but this has not been examined. In the present study, we examined the effects of negative top-down cognition using an FBI procedure in which a fake body was instructed to be viewed as a negative self-body. Results showed that the FBI was inhibited when instructed to view it as a negative self-body. The present results indicates that top-down cognition may be a factor that inhibits the creation of a sense of body ownership.
