Abstract：
Vocal production learning and beat perception and synchronization (BPS) share some common characteristics, which makes the vocal learning and rhythmic synchronization hypothesis (VLH) a reasonable explanation for the evolution of the capability for rhythmic synchronization. However, even in vocal learners, it is rare to see non-human animals demonstrate BPS to human music. Therefore, the first objective of this article is to propose some possible reasons why we do not see BPS in budgerigars, an excellent vocal learning species, while presenting some of my own findings. The second objective of this article is to propose a seamless bridge to connect the capability for vocal learning and BPS in locomotion. For this purpose, I present my own findings, wherein cockatiels spontaneously sang in synchrony with a melody of human music. This behavior can be considered a vocal version of BPS. Therefore, it can establish a connection between these two capabilities. This article agrees with the possibility that some mechanisms other than the vocal learning system may enable BPS, contrary to the original idea of VLH. Nevertheless, it is still reasonable to connect the capability for vocal learning and that for BPS. At the very least, the capability for vocal learning may contribute to the evolution of BPS. From these arguments, this article also proposes a scenario which includes vocalizing in synchrony as a driving force for the evolution of BPS and the capability for music production.
摘要：
声乐制作学习和节拍感知和同步(BPS)有一些共同的特点，这使声乐学习和节奏同步假设（VLH）对节奏同步能力的演变做出了合理的解释。然而,即使在声乐学习者中，很少看到非人类动物向人类音乐展示BPS。因此,本文的第一个目的是提出一些可能的原因，为什么我们没有在鹦鹉中看到BPS，一个优秀的声乐学习物种，同时提出我自己的一些发现。本文的第二个目标是提出一个无缝的桥梁，以连接语音学习和运动中的BPS能力。为此,我提出我自己的发现,其中花花公子自发地与人类音乐的旋律同步唱歌。这种行为可以被认为是BPS的声音版本。因此,它可以在这两种能力之间建立联系。本文同意除声乐学习系统以外的其他机制可能启用BPS的可能性，与VLH的最初想法相反。然而，将声乐学习的能力和BPS的能力联系起来仍然是合理的。至少,声乐学习能力可能有助于BPS的进化。从这些论点中，本文还提出了一种方案，其中包括同步发声作为BPS发展的驱动力和音乐制作的能力。
