眼睛在社会交流中起着至关重要的作用。然而，到目前为止，眨眼只受到了很少的关注。我们以前曾证明，受试者在观看相同的视频故事时会同步眨眼(Nakano等人。载于Proc R Soc B 276：3635-3644,2009)。因此，我们假设在面对面的对话中，听者和说话者之间的眨眼是同步的。在这里，我们展示了当听众观看演讲者面部的特写视频片段(带声音)时，听众在演讲者眨眼之后，延迟了0.25-0.5%S。此外，这种夹带是由说话者在讲话结束和停顿时眨眼所选择性地触发的。当观看没有声音的相同视频片段时，没有观察到眨眼夹带，这表明眨眼夹带不是自动模仿。因此，我们认为眨眼夹带反映了相互作用者之间的顺利交流。
The eyes play an essential role in social communication. Eyeblinks, however, have thus far received minor attention. We previously showed that subjects blink in synchrony while viewing the same video stories (Nakano et al. in Proc R Soc B 276:3635-3644, 2009). We therefore hypothesized that eyeblinks are synchronized between listener and speaker in face-to-face conversation. Here, we show that listeners blinked with a delay of 0.25-0.5 s after the speaker blinked when the listeners viewed close-up video clips (with sound) of the speaker's face. Furthermore, this entrainment was selectively triggered by speaker's eyeblinks occurring at the end and during pauses in speech. Eyeblink entrainment was not observed when viewing identical video clips without sound, indicating that blink entrainment was not an automatic imitation. We therefore suggest that eyeblink entrainment reflects smooth communication between interactants.
