Seven experiments show that an event onset shift (EOS) in an auditory sequence causes an involuntary phase correction response (PCR) in synchronized finger tapping. This PCR is (a) equally large in inphase and antiphase tapping; (b) reduced but still present when the EOS occurs in either of two interleaved (target-distractor) sequences; (c) unaffected by increased pitch separation between these sequences; (d) asymptotic in magnitude as EOS magnitude increases, unlike the intentional PCR to expected phase shifts; and (e) enhanced when the EOS precedes the onset of tapping, because of phase resetting. Thus, phase correction is revealed to be partially automatic and partially under voluntary control, and to be based mainly on temporal information derived from simple onset detection.
七项实验表明，听觉序列中的事件起始偏移（EOS）会在同步手指敲击时引发非自愿的相位校正反应（PCR）。这种PCR具有以下特点：（a）在同相和反相敲击时大小相同；（b）当EOS出现在两个交错的（目标-干扰物）序列中的任何一个时，反应减弱但仍然存在；（c）不受这些序列之间音高间隔增加的影响；（d）与对预期相位偏移的有意PCR不同，随着EOS幅度的增加，其幅度呈渐近状态；（e）由于相位重置，当EOS先于敲击起始时反应增强。因此，相位校正被证明部分是自动的，部分受自主控制，并且主要基于从简单起始检测中获得的时间信息。
