The present study examined changes in timing at the transition from synchronization to continuation tapping and the role played by knowledge of the transition. Three experiments employed a pseudo-synchronization paradigm: At the transition, the pacing tones were replaced by identical feedback tones. In Experiment 1, participants were not informed when the transition would occur. Immediately following the transition, an acceleration of tapping was observed. In Experiment 2, participants were informed about the exact position of the transition, which was in addition marked by a pitch change. Nonetheless, the same acceleration occurred. Experiment 3 dissociated the actual from the expected position of the transition, without changing the results. In addition, the delay of the feedback tones was manipulated and was found to affect the rate of tapping in the continuation phase. A single delayed tone at the transition had no lasting effect, however. The results are interpreted in light of the synchronization-continuation model of Vorberg and Wing [Vorberg, D., & Wing, A. (1996). Modelling variability and dependence in timing. In H. Heuer, & S. W. Keele (Eds.), Handbook of perception and action, Vol. 2 (pp. 181-262). San Diego: Academic Press], with the added assumption that the synchronization tapping strategy is maintained in the continuation phase.
本研究考察了从同步敲击到持续敲击转变过程中的时间变化以及转变知识所起的作用。三个实验采用了伪同步范式：在转变时，节拍音被相同的反馈音取代。在实验1中，未告知参与者转变何时发生。转变后立即观察到敲击加速。在实验2中，告知参与者转变的确切位置，此外还用音高变化进行了标记。然而，同样的加速现象依然出现。实验3将转变的实际位置与预期位置区分开来，结果并未改变。此外，对反馈音的延迟进行了操控，发现其会影响持续阶段的敲击速率。不过，在转变时单个延迟音并无持久影响。根据沃伯格和温的同步 - 持续模型[沃伯格，D.，& 温，A.（1996）。对时间中的变异性和依赖性进行建模。载于H. 豪尔 & S. W. 基尔（编），《感知与行动手册》，第2卷（第181 - 262页）。圣地亚哥：学术出版社]对结果进行了解释，并额外假定在持续阶段保持同步敲击策略。
