In a recent study of musicians' sensorimotor synchronization with auditory sequences composed either of beat and subdivision tones differing in pitch or of beat tones only, Repp (2009) found that the phase correction response (PCR) to perturbed beats was inhibited by the presence of subdivisions regardless of whether beats and subdivisions formed integrated or segregated perceptual streams. The present study used a different paradigm in which perturbed subdivisions triggered the PCR. At the slower of two sequence tempi, the PCR was equally large in integrated and segregated conditions, but at the faster tempo stream segregation reduced the PCR substantially. This new finding indicates that although the PCR is strongly resistant to auditory stream segregation, it is not totally immune to it.
在最近一项关于音乐家与由音高不同的节拍和细分音调组成的听觉序列或仅由节拍音调组成的听觉序列进行感觉运动同步的研究中，雷普（2009年）发现，无论节拍和细分音调形成整合的还是分离的感知流，细分音调的存在都会抑制对受干扰节拍的相位校正反应（PCR）。本研究采用了一种不同的范式，即受干扰的细分音调触发PCR。在两个序列节奏中较慢的那个节奏下，在整合和分离条件下PCR同样大，但在较快节奏下，流分离显著降低了PCR。这一新发现表明，尽管PCR对听觉流分离具有很强的抗性，但它并非完全不受其影响。
