How do expert storytelling artists captivate audiences with a single performance? In<br/> study 1, we observed the eyeblink responses of expertized 7 of 20 audience members<br/> (10 male and 10 female, aged 16 to 67 years; <i>M </i>=40<i>.</i>6, <i>SD </i>=16<i>.</i>4) at the performance<br/> of two professional story-telling Rakugo artists. With using a surrogate data method,<br/>the statistically significant synchronization of eyeblinks among audience members was<br/> detected when performers changed scenes and characters and immediately after the<br/> performer delivered words essential to the understanding of the story. In study 2, we<br/> conducted a laboratory experiment with 32 (19 male and 13 female) participants aged<br/> 20 to 34 years (<i>M </i>=22<i>.</i>56, <i>SD </i>=2<i>.</i>85) to examine whether the expertise of the story-<br/>teller affected the frequency and intensity of synchronization of eyeblinks by recording<br/> each participant's eyeblinks. The synchronization of eyeblinks was also detected in this<br/> study that each participant viewed videotapes alone, which eliminated potential au-<br/>dience interaction. The participants who were assigned to the watching a videotaped<br/> performance of an expert storyteller displayed frequent synchronized eyeblinks and had<br/> a higher score of transportation into the narrative world of Rakugo compared to those<br/> were assigned to watch a videotaped performance of a novice. These results imply<br/> that expert performers gain a listener's unintentional process of attention as well as<br/> somatic-emotional responses, evidenced by synchronized eyeblinks.
