人与人之间的接触据说对社会互动有重大影响。我们使用最后通牒游戏来检验机器人的触摸是否可以抑制对机器人的负面感觉。我们设置了两种实验条件：一种是触摸条件，当机器人触摸参与者的手臂时，向他/她提出不公平的建议；另一种是不接触条件，即当同一机器人没有触摸时，提出不公平的建议。我们比较了两种情况下脑电测得的额叶内侧负波(MFN)，其波幅与不公平感相关。结果表明，无接触状态下的MFN幅值大于接触状态下的MFN幅度。这表明，来自机器人的触摸可能会抑制对机器人的不公平感。我们的发现表明，机器人的触摸可以通过人与机器人的互动增强对机器人的积极感觉。
Interpersonal touch is said to have significant effects on social interaction. We used the ultimatum game to examine whether touch from a robot could inhibit a negative feeling to the robot. We set two experimental conditions: the one was “touch condition” in which unfair proposals were offered to a participant when a robot touched his/her arm and the other was “no touch condition” in which unfair proposals were offered when the same robot did not. We compared Medial Frontal Negativity (MFN) measured by EEG, whose amplitude is correlated with feeling of unfairness, between the two conditions. Result shows that MFN amplitude was larger in the no touch condition than in the touch condition. This indicates that touch from a robot may inhibit a sense of unfairness for the robot. Our finding suggests that touch from a robot could enhance positive feeling to the robot through human-robot interaction.
