频谱分析被应用于研究人类节奏同步的可变性，以视觉，听觉或组合的视觉-视觉节拍器的约2 Hz，以及可变性，在连续敲击以相同的速度，或没有视觉或听觉反馈。在同步中，视觉条件下的变异性大于听觉和组合条件下的变异性，但仅低于约0.3 Hz的频率。因此，似乎有至少两个来源的变异同步，一个是模态独立的，并限于间隔短于3秒，和其他模态依赖性和明显的缓慢“漂移”，特别是在视觉任务。在连续敲击，变异性并不可靠地依赖于存在或反馈的方式。然而，频谱分析显示，在0.08赫兹左右的时间结构的变化（约12秒或24水龙头的一段时间），这大致同意与文献中报道的早期研究结果。(C)2002爱思唯尔科技有限公司。保留所有权利。
Spectral analysis was applied to study the variability in human rhythmic synchronization to a visual, auditory or combined auditory-visual metronome of about 2 Hz, as well as the variability in continuation tapping at the same rate with or without visual or auditory feedback. In synchronization, variability was larger in the visual condition than in the auditory and combined conditions, but only below frequencies of about 0.3 Hz. Thus, there seem to be at least two sources of variability in synchronization, one being modality-independent and limited to intervals shorter than 3 s, and the other being modality-dependent and evident as slow "drift", especially in the visual task. In continuation tapping, variability did not depend reliably on the presence or modality of feedback. However, spectral analysis revealed a change in the temporal structure of variability around 0.08 Hz (a period of about 12 s or 24 taps), which roughly agrees with earlier findings reported in the literature.
