人际同步性是指社会互动过程中个体之间动作的时间协调。例如，研究表明，听众在观看演讲者脸部的特写视频剪辑时，他们的眨眼次数会与演讲者的眨眼同步，尤其是在演讲的断点处。我们假设患有自闭症谱系障碍（ASD）的人不会观察到这种人际同步行为，其特点是社交沟通受损。为了验证这一假设，我们检查了患有自闭症谱系障碍的成年人的眨眼夹带情况。正如我们之前报道的，没有自闭症谱系障碍的成年人在观看演讲者的整个面部时，其眨眼与演讲者在演讲停顿时的眨眼显着同步。然而，当没有自闭症谱系障碍的成年人只看说话者的眼睛或嘴巴时，显着的眨眼同步消失，这表明来自整个面部的信息，包括来自眼睛和嘴巴的信息，对于眨眼夹带是必要的。相比之下，自闭症谱系障碍参与者没有表现出与说话者任何眨眼同步，即使同时观察说话者的眼睛和嘴巴也是如此。自闭症谱系障碍患者缺乏对说话者的眨眼引导，这表明他们无法暂时调整自己以适应他人的行为。时间协调的缺陷可能会损害与他人的有效社交沟通。 (C) 2011 Elsevier Ltd. 保留所有权利。
Interpersonal synchrony is the temporal coordination of movements between individuals during social interactions. For example, it has been shown that listeners synchronize their eyeblinks to a speaker's eyeblinks, especially at breakpoints of speech, when viewing a close-up video clip of the speaker's face. We hypothesized that this interpersonal synchronous behavior would not be observed in individuals with autism spectrum disorders (ASD), which are characterized by impaired social communication. To test this hypothesis, we examined eyeblink entrainments in adults with ASD. As we reported previously, the eyeblinks of adults without ASD were significantly synchronized with the speaker's eyeblinks at pauses in his speech when they viewed the speaker's entire face. However, the significant eyeblink synchronization disappeared when adults without ASD viewed only the speaker's eyes or mouth, suggesting that information from the whole face, including information from both the eyes and the mouth, was necessary for eyeblink entrainment. By contrast, the ASD participants did not show any eyeblink synchronization with the speaker, even when viewing the speaker's eyes and mouth simultaneously. The lack of eyeblink entrainment to the speaker in individuals with ASD suggests that they are not able to temporally attune themselves to others' behaviors. The deficits in temporal coordination may impair effective social communication with others. (C) 2011 Elsevier Ltd. All rights reserved.
