In two experiments, the effect of feedback delay on synchronization performance was examined. In Experiment 1, whether feedback delay has an effect on the asynchrony between tap and click was investigated, and a transfer effect between conditions, observed in a preliminary experiment, was studied. Experiment 2 served as a control experiment that assured that the effects were not caused by order effects. A linear relationship between the size of the delay and the asynchrony between tap and click was observed; that is, with increasing delay, the size of the asynchrony increased as well. The results support an extended version of the Paillard-Fraisse hypothesis that accounts for the results observed in synchronization tasks in which more than a single source of feedback from the tap is available. The results indicate that all tap-related information is integrated into a joint event code representing that tap at a central level. These codes are superimposed on click-related codes and are therefore responsible for the observed asynchronies. Moreover, the results suggest that tap-related codes arise from a linear combination of their tactile-kinesthetic and auditory components.
在两项实验中，研究了反馈延迟对同步性能的影响。在实验1中，研究了反馈延迟是否对敲击与点击之间的异步性有影响，并对在初步实验中观察到的不同条件之间的迁移效应进行了研究。实验2作为对照实验，以确保这些效应不是由顺序效应引起的。观察到延迟大小与敲击和点击之间的异步性之间存在线性关系；也就是说，随着延迟增加，异步性的大小也增加。这些结果支持了帕亚尔-弗雷斯假设的扩展版本，该版本解释了在同步任务中观察到的结果，在这些任务中，来自敲击的反馈不止一个来源。结果表明，所有与敲击相关的信息都被整合到一个在中枢水平上代表该敲击的联合事件代码中。这些代码叠加在与点击相关的代码上，因此是观察到的异步性的原因。此外，结果表明，与敲击相关的代码来自其触觉动觉和听觉成分的线性组合。
