Action-effect binding and agency.

Abstract

The sense of agency is a pervasive phenomenon that accompanies conscious acting and extends to the consequences of one's actions in the environment. Subjective feelings of agency are typically explained in terms of predictive processes, based on internal forward models inherent to the sensorimotor system, and postdictive processes, i.e., explicit, retrospective judgments by the agent. Only recently, research has begun to elucidate the link between sense of agency and more basic processes of human action control. The present study was conducted in this spirit and explored the relation between short-term action-effect binding and explicit agency judgments. We found evidence for such a link in that the participants' short-term action-effect binding predicted subsequent agency ratings. This offers a new perspective on the sense of agency, providing an additional mechanism (together with predictive and postdictive processes) that may underlie its formation.
