The experience of agency refers to the phenomenal experience of being the causal source of one's own actions, and through them, the course of events in the outside world. This experience is crucial for the production of adaptive actions, and for the adequate communication of felt action control to peers. The present study examines the possibility that, on certain occasions and under specific internal and external constraints, people rely on explicit social information provided by their peers to revise their self-reports of perceived control, i.e., their judgment of agency. To test this hypothesis, we adapted a task based on an interactive computer game. We manipulated well-known sensorimotor agency cues related to action control, as well as social information communicated to participants by two advisors. We measured the contribution of social and non-social sources of information to agency judgments. We found that at the single-trial level, participants align their JoA with advisor feedback based on their own performance during the task, the type of feedback provided by advisors, and the interaction of this social feedback with the sensorimotor agency cues. At the same time, JoA alignment in previous trial also predicted participants' tendency to revise their JoA after social feedback. Overall, these results demonstrate that agency judgment is subject to social influence. This influence is the result of the integration of social and non-social information at the scale of a single judgment, while also being driven by repeated past interactions with peers.
