Researchers have puzzled over the phenomenon in sensorimotor timing that people tend to tap ahead of time. When synchronizing movements (e.g., finger taps) with an external sequence (e.g., a metronome), humans typically tap tens of milliseconds before event onsets, producing the elusive negative asynchrony. Here, we present 24 metronome-tapping data sets from 8 experiments with different experimental settings, showing that less negative asynchrony is associated with lower tapping variability. Further analyses reveal that this negative mean-SD correlation of asynchrony is likely to be observed for sequence types appropriate for synchronization, as indicated by the statistically negative lag 1 autocorrelation of inter-response intervals. The reported findings indicate an association between negative asynchrony and timing variability.
研究人员对感知运动定时现象感到困惑，即人们往往会提前敲击。当将运动（例如手指敲击）与外部序列（例如节拍器）同步时，人类通常会在事件开始前数十毫秒敲击，从而产生难以捉摸的负异步。在这里，我们展示了 24 个节拍器敲击数据集，来自 8 个具有不同实验设置的实验，表明负异步与敲击变化性降低有关。进一步的分析表明，这种负平均-SD 异步相关性很可能是针对适合同步的序列类型观察到的，这表明响应间间隔的滞后 1 自相关具有统计学上的负性。报告的研究结果表明，负异步与定时变化性之间存在关联。
