Figure 1. Motor agency task.
Illustration of the collision paradigm that was used to estimate the degree of sense of agency experienced by each individual for two different types of events. LEFT: other-triggered collisions with a pendulum that was released by the experimenter; RIGHT: self-produced collisions with a pendulum that was released by the participants. Under both conditions, the subjects were required to remain the hand-held objet immobile and to stop the fall of the pendulum.
