世界上绝大多数的音乐都是韵律的，即在多个时间尺度上具有周期性结构。与节拍周期的同步序列相比，非等时节奏的韵律结构是否改善了与节拍的同步？节拍同步通常与听觉刺激有关，但人们能够从具有韵律结构的有节奏的视觉序列中提取节拍吗？我们通过向听者呈现在听觉或视觉通道中同步或非同步的节奏模式来解决这些问题，并要求他们敲击节拍，这被规定为每隔800毫秒发生一次。对于听觉模式，我们发现，与相同节拍周期的同步模式相比，强节律结构并没有提高整体同步的准确性，尽管它确实影响了更高水平的抽头模式。在一些节拍沉默的弱韵律模式中，同步性受到损害。对于视觉模式，我们发现参与者通常无法同步到节拍的非等时节奏，或快速的等时节奏。这表明，节拍感知和同步与听觉系统有着特殊的亲和力。
The great majority of the world's music is metrical, i.e., has periodic structure at multiple time scales. Does the metrical structure of a non-isochronous rhythm improve synchronization with a beat compared to synchronization with an isochronous sequence at the beat period? Beat synchronization is usually associated with auditory stimuli, but are people able to extract a beat from rhythmic visual sequences with metrical structure? We addressed these questions by presenting listeners with rhythmic patterns which were either isochronous or non-isochronous in either the auditory or visual modality, and by asking them to tap to the beat, which was prescribed to occur at 800-ms intervals. For auditory patterns, we found that a strongly metrical structure did not improve overall accuracy of synchronization compared with isochronous patterns of the same beat period, though it did influence the higher-level patterning of taps. Synchronization was impaired in weakly metrical patterns in which some beats were silent. For the visual patterns, we found that participants were generally unable to synchronize to metrical non-isochronous rhythms, or to rapid isochronous rhythms. This suggests that beat perception and synchronization have a special affinity with the auditory system.
