将运动活动带入有节奏的听觉刺激，即“保持节拍”的能力，依赖于支持声音模仿的神经适应吗？这是声乐学习和同步假说的前提，最近提出用来解释这种行为的基础(A.Patel，2006，Musical Rhythm，Language Rhythm，and Human Event，Music Percept，24，99-104)。在目前的研究之前，只有声音模仿，包括人类、鹦鹉和虎皮鹦鹉，才被证明能够被机动缠绕。在这里，我们证明了一种发声不太灵活的动物，加州海狮(Zalophus Calfornianus)，可以学习将头部上下摆动以符合三个标准：不复制刺激的行为反应；表演转移到一系列新的节奏；以及对复杂的音乐刺激的夹带。这些发现表明，运动对有节奏的声音的夹带能力并不依赖于声音模仿的能力，而且在动物界可能比之前假设的更广泛。
Is the ability to entrain motor activity to a rhythmic auditory stimulus, that is "keep a beat," dependent on neural adaptations supporting vocal mimicry? That is the premise of the vocal learning and synchronization hypothesis, recently advanced to explain the basis of this behavior (A. Patel, 2006, Musical Rhythm, Linguistic Rhythm, and Human Evolution, Music Perception, 24, 99-104). Prior to the current study, only vocal mimics, including humans, cockatoos, and budgerigars, have been shown to be capable of motoric entrainment. Here we demonstrate that a less vocally flexible animal, a California sea lion (Zalophus californianus), can learn to entrain head bobbing to an auditory rhythm meeting three criteria: a behavioral response that does not reproduce the stimulus; performance transfer to a range of novel tempos; and entrainment to complex, musical stimuli. These findings show that the capacity for entrainment of movement to rhythmic sounds does not depend on a capacity for vocal mimicry, and may be more widespread in the animal kingdom than previously hypothesized.
