Temporal coordination in performance

我们根据接收到的感官信息协调行为的能力是非凡的；从视觉系统到语言和运动技能，当感觉线索发生变化时，人们表现出了一种特殊的适应能力。特别是，在说话、唱歌和表演音乐等听觉运动行为中，时间协调是快速而毫不费力的：人们迅速协调他们的行动，以响应音乐和语言特征的广泛的声学变化。音乐表演和对话演讲中的群体互动必须遵守时间限制，否则协调就会崩溃。然而，个体的时间协调能力差异很大；从简单的敲击到对话式的演讲或演奏音乐，个体和群体在时间协调方面表现出巨大的差异，这些差异至今仍未得到解释。我们最近发现了个体听觉-运动耦合的限制，这表明了个体之间时间协调的第一个标志，在音乐和会话语言中。我们利用这些发现建立了优越的时间协调和缺陷的计算模型。

Our capacity to coordinate our behaviour with incoming sensory information is extraordinary; from visual systems to language and motor skills, people display an exceptional ability to adapt their actions when sensory cues change. In particular, temporal coordination during auditory-motor behaviours such as speaking, singing, and performing music, is fast and effortless: people coordinate their actions quickly in response to a wide range of acoustic changes that characterize music and speech. Group interactions in music performance and conversational speech must adhere to temporal constraints, or else coordination breaks down. Yet individuals vary considerably in their temporal coordination abilities; from simple tapping to conversational speech or performing music, individuals and groups exhibit large differences in temporal coordination that remain unexplained. We have recently uncovered constraints on individuals' auditory-motor coupling that indicate the first markers of temporal coordination among individuals, in music and conversational speech. We use these findings to build computational models of both superior temporal coordination and of deficits.
