Temporal coordination in performance

我们协调自己的行为与传入的感觉信息的能力是非同寻常的；从视觉系统到语言和运动技能，当感觉线索改变时，人们表现出非凡的能力来调整他们的行动。特别是，在说话、唱歌和演奏音乐等听觉-运动行为中，时间协调是快速和毫不费力的：人们迅速协调他们的行动，以应对音乐和言语中广泛的声学变化。音乐表演和会话演讲中的群体互动必须遵守时间限制，否则协调就会中断。然而，个体在时间协调能力上有相当大的差异；从简单的敲击到对话演讲或演奏音乐，个人和群体在时间协调方面表现出巨大的差异，这些差异仍然无法解释。我们最近发现了对个体听觉-运动耦合的限制，这表明在音乐和对话语言中，个体之间的时间协调是第一个标志。我们使用这些发现来建立时间上的优越协调性和赤字的计算模型。

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.
