Speech and music might involve specific cognitive rhythmic timing mechanisms related to differences in the dominant rhythmic structure. We investigate the influence of different motor effectors on rate-specific processing in both domains. A perception and a synchronization task involving syllable and piano tone sequences and motor effectors typically associated with speech (whispering) and music (finger-tapping) were tested at slow (2 Hz) and fast rates (4.5 Hz). Although synchronization performance was generally better at slow rates, the motor effectors exhibited specific rate preferences. Finger-tapping was advantaged compared to whispering at slow but not at faster rates, with synchronization being effector-dependent at slow, but highly correlated at faster rates. Perception of speech and music was better at different rates and predicted by a fast general and a slow finger-tapping synchronization component. Our data suggests partially independent rhythmic timing mechanisms for speech and music, possibly related to a differential recruitment of cortical motor circuitry.
言语和音乐可能涉及与主导节奏结构差异相关的特定认知节奏定时机制。我们研究了不同运动效应器对这两个领域中特定速率处理的影响。在缓慢（约2赫兹）和快速（约4.5赫兹）速率下，测试了涉及音节和钢琴音调序列以及通常与言语（低语）和音乐（手指敲击）相关的运动效应器的感知和同步任务。尽管同步性能通常在缓慢速率下更好，但运动效应器表现出特定的速率偏好。与低语相比，手指敲击在缓慢速率下具有优势，但在较快速率下则不然，同步在缓慢速率下依赖于效应器，但在较快速率下高度相关。言语和音乐的感知在不同速率下更好，并且由快速通用和缓慢手指敲击同步成分预测。我们的数据表明，言语和音乐的节奏定时机制部分独立，可能与皮质运动回路的不同募集有关。
