Social exclusion in a virtual Cyberball game reduces the virtual hand illusion.

Summary

Social exclusion reduces people's sense of agency and ownership over a virtual hand. In a virtual hand illusion experiment, participants who were excluded during a Cyberball game reported weaker feelings of ownership and agency and showed reduced physiological and behavioral measures of these experiences compared to included participants. Synchrony between the virtual hand and the participant's own hand strengthened both ownership and agency across all measures, but this effect was weaker for excluded individuals. The findings indicate that social context shapes fundamental aspects of self-perception.

Abstract

Sense of ownership and agency are two important aspects of the minimal self, but how self-perception is affected by social conditions remains unclear. Here, we studied how social inclusion or exclusion of participants in the course of a virtual Cyberball game would affect explicit judgments and implicit measures of ownership and agency (proprioceptive drift, skin conductance responses, and intentional binding, respectively) in a virtual hand illusion paradigm, in which a virtual hand moved in or out of sync with the participants' own hand. Results show that synchrony affected all four measures. More importantly, this effect interacted with social inclusion/exclusion in the Cyberball game for both ownership and agency measure, showing that social exclusion reduces perceived agency and ownership.
