人型エージェントによる不気味な笑顔表出に対する小脳の内部モデルを用いた異常検知メカニズムの記述の試み

抄録

In observing the smile expressed by a humanlike agent, it sometimes elicits negative emotional valence. Our hypotheses were as follows: (i)human expeceted the facial expression of others, based on the internal model of smile expression formed by cerebellum. (ii)the movement of smile expression of humanlike agent were slightly different from that of human, and (iii)which causes the observer to detect the error when observing the smile expression of humanlike agent as it was different from expected movement. In this paper, the brain-functional model was proposed providing for explanation for the error detection.
