Kinesthesis pertains to the perception of moving body parts, while the sense of agency refers to the experience of controlling one's action-effects. Based on previous work, we hypothesized that the sense of agency would decrease in joint action with a robot compared to a human partner. Pairs of participants were jointly manipulating two interconnected haptic devices enabling them to feel each other's forces. Unbeknown to participants, their partner was sometimes replaced by a robot. The sense of agency was assessed using intentional binding, which refers to a contraction of perceived time between an action and its effect for intentional actions, and participants' judgment of their contribution to joint action. Participants judged their contribution as higher when they were initiating action and when they were paired with the robot. By contrast, intentional binding occurred only with a human partner. This outcome supports the hypothesis that human-robot joint action hinders intentional binding.
动觉是指对运动中身体部位的感知，而主体感是指对自身动作效果的控制体验。基于先前的研究，我们假设在与机器人进行联合动作时，主体感会比与人类伙伴进行联合动作时降低。参与者成对地操作两个相互连接的触觉设备，使他们能够感受到彼此的力量。参与者不知道的是，有时他们的伙伴会被机器人取代。主体感是通过意图绑定来评估的，它是指对有意动作的动作和效果之间感知时间的收缩，以及参与者对自己在联合动作中的贡献的判断。当参与者发起动作并与机器人配对时，他们会认为自己的贡献更高。相比之下，只有在与人类伙伴一起时才会发生意图绑定。这一结果支持了这样一种假设，即人机联合动作会阻碍意图绑定。
