An investigation of "We" agency in co-operative joint actions.

Sense of agency refers to the sense that I am controlling an action or outcome, and is associated with a perceived compression of the temporal interval between these events known as intentional binding (IB). Though most IB studies focus on individually performed actions, some reveal the existence of shared implicit agency among joint actors, suggesting the formation of a shared "we" identity that may be sensitive to the intentions and actions of all actors. While current understanding of this shared agentic identity is far from clear, the present study used variants of the IB paradigm involving truly co-operative actions to investigate (1) the relative strength of individual and joint agency, and (2) whether different complementary roles modulate the sense of agency among joint actors.
