The "sense of agency" refers to the subjective awareness that one is initiating, executing, and controlling one's own volitional actions in the world. It is the pre-reflective awareness or implicit sense that it is me who is presently executing bodily movement(s) or thinking thoughts. In normal, non-pathological experience, the SA is tightly integrated with one's "sense of ownership" (SO), which is the pre-reflective awareness or implicit sense that one is the owner of an action, movement or thought.
