人类经常对行动和结果之间的因果关系非常间接的事件感到一种代理感（SoA）。我们已经研究了如何中间（这里，一个机器人的手）干预之间的行动和结果的事件可能会改变SoA，使用有意的约束措施。机器人手要么与参与者进行相同的运动（主动一致），要么与另一个手指进行类似的运动（主动不一致）。结合显着减少，在积极的不一致性相对于积极的一致性条件，这表明，改变实施方式的影响SoA。然而，绑定效果之间的条件下，机器人的手作出一致的运动，和条件下，没有机器人的手参与，这表明中间和体现的事件不减少SoA。我们认为，人类的代理感涉及意图和任意结果之间的统计关联，以及用于实现结果的感觉运动手段的效应器特定匹配。(C)2015 Elsevier Inc.

Humans regularly feel a sense of agency (SoA) over events where the causal link between action and outcome is extremely indirect. We have investigated how intermediate (here, a robotic hand) events that intervene between action and outcome may alter SoA, using intentional binding measures. The robotic hand either performed the same movement as the participant (active congruent), or performed a similar movement with another finger (active incongruent). Binding was significantly reduced in the active incongruent relative to the active congruent condition, suggesting that altered embodiment influences SoA. However, binding effects were comparable between a condition where the robot hand made a congruent movement, and conditions where no robot hand was involved, suggesting that intermediate and embodied events do not reduce SoA. We suggest that human sense of agency involves both statistical associations between intentions and arbitrary outcomes, and an effector-specific matching of sensorimotor means used to achieve the outcome.
