延迟的听觉反馈（delayed auditory feedback，EAF）会导致感知和动作之间的冲突，从而破坏序列的产生。不同的延迟长度导致不同的中断量，这可以反映反馈起始相对于产生的响应间间隔的相位位置，或者动作和声音之间的绝对时间间隔。两个实验解决了这个问题，通过比较的影响，传统的同步，它使用一个恒定的时间间隔，与延迟，调整时间间隔，以保持相互响应间隔内的反馈起始的相位位置。参与者在键盘上演奏简单的等音阶旋律，或敲击等音阶节拍，以三种生产率。中断是最好的预测反馈起始的相位位置，并减少时，反馈起始形成谐波相位比（相位同步）。两种延迟类型导致类似的效果。不同的运动任务（旋律生产与攻丝）导致略有不同的模式中断跨阶段，可能与不同的任务要求。一般来说，这些结果支持的观点，即感知和行动是在相对时间，而不是绝对时间协调。(c)2007 Elsevier B.V.保留所有权利。
Delayed auditory feedback (DAF) causes asynchronies between perception and action that disrupt sequence production. Different delay lengths cause differing amounts of disruption that may reflect the phase location of feedback onsets relative to produced inter-response intervals, or the absolute temporal separation between actions and sounds. Two experiments addressed this issue by comparing the effects of traditional DAF, which uses a constant temporal separation, with delays that adjust temporal separation to maintain the phase location of feedback onsets within interresponse intervals. Participants played simple isochronous melodies on a keyboard, or tapped an isochronous beat, at three production rates. Disruption was best predicted by the phase location of feedback onsets, and diminished when feedback onsets formed harmonic phase ratios (phase synchrony). Both delay types led to similar effects. Different movement tasks (melody production versus tapping) led to slightly different patterns of disruption across phase that may relate to differing task demands. In general, these results support the view that perception and action are coordinated in relative rather than absolute time. (c) 2007 Elsevier B.V. All rights reserved.
