Sense of agency refers to the feeling of controlling an external event through one’s own
action. On one influential view, agency depends on how predictable the consequences
of one’s action are, getting stronger as the match between predicted and actual effect
of an action gets closer. Thus, sense of agency arises when external events that follow
our action are consistent with predictions of action effects made by the motor system
while we perform or simply intend to perform an action. According to this view, agency
is inferred retrospectively, after an action has been performed and its consequences are
known. In contrast, little is known about whether and how internal processes involved
in the selection of actions may influence subjective sense of control, in advance of the
action itself, and irrespective of effect predictability. In this article, we review several
classes of behavioral and neuroimaging data suggesting that earlier processes, linked to
fluency of action selection, prospectively contribute to sense of agency. These findings
have important implications for better understanding human volition and abnormalities of
action experience.
