我们提出了一个分解的神经认知机制，可能是基于间隔的定时和节奏夹带。接下来，我们将讨论最近的研究表明，节奏夹带是特定于人类和一组选定的鸟类物种，但令人惊讶的是，在非人类灵长类动物中并不明显。在这些研究的基础上，我们提出了渐进听觉进化假说，这表明人类与其他灵长类动物完全共享基于间隔的计时，但只有部分共享节奏夹带（或基于节拍的计时）的能力。这一假设适应了非人灵长类动物（即，猕猴）在单间隔任务（如间隔再现、分类和拦截）中的表现与人类相当，但在多间隔任务（如节奏诱导、同步和连续）中表现出差异。此外，这与猕猴显然可以在视觉领域同步，但在听觉领域表现出较低的敏感性的观察结果一致。最后，虽然猕猴对基于间隔的计时和节奏分组很敏感，但非人类灵长类动物的听觉和运动系统之间缺乏强耦合可能是猕猴无法以人类的方式有节奏地进行的原因。
We propose a decomposition of the neurocognitive mechanisms that might underlie interval-based timing and rhythmic entrainment. Next to reviewing the concepts central to the definition of rhythmic entrainment, we discuss recent studies that suggest rhythmic entrainment to be specific to humans and a selected group of bird species, but, surprisingly, is not obvious in non-human primates. On the basis of these studies we propose the gradual audiomotor evolution hypothesis that suggests that humans fully share interval-based timing with other primates, but only partially share the ability of rhythmic entrainment (or beat-based timing). This hypothesis accommodates the fact that non-human primates (i.e., macaques) performance is comparable to humans in single interval tasks (such as interval reproduction, categorization, and interception), but show differences in multiple interval tasks (such as rhythmic entrainment, synchronization, and continuation). Furthermore, it is in line with the observation that macaques can, apparently, synchronize in the visual domain, but show less sensitivity in the auditory domain. And finally, while macaques are sensitive to interval-based timing and rhythmic grouping, the absence of a strong coupling between the auditory and motor system of non-human primates might be the reason why macaques cannot rhythmically entrain in the way humans do.
