Recently, it is suggested that a person's cognition on another person is influenced by how the person is responding to the other, that is hypothesized as intrapersonal responding-cascade. Although the hypothesis has been tested in the situation of gaze interaction, its scalability for other modalities are not clear. In this study, we test the hypothesis by coping with a psychological distance sense in the situation that a subject and a robot approaches each other. From the experiment, we found only a weak tendency of the effect of subjects' own behavior on the subjects' impression on the robot, that is when a subject and the robot approaches each other, the subjects who have positive impression of friendliness formed stronger feeling as if it might have positive feeling on them. We could not find any other statistical significance in the current experimental setting although there were not any evidences that reject the hypothesis.
