Does the perception of our actions differ from the perception of other individuals' actions when we observe them, like other individual's actions, in an offline perspective? Previous studies, using recognition as well as prediction judgments, suggest that it does even if the stimulus information is reduced to a single moving point-light. Here, we assessed whether this difference also affects the timing of actions. This was tested in two experiments, using a specific synchronization task. After some practice, self-generated action events were anticipated faster than other action events, provided that the anticipation could not be accomplished sufficiently well on the basis of easily detectable cues. The results are discussed with regard to the previous findings of off-line authorship effects in action perception.
当我们像观察其他人的动作那样，以离线视角观察自己的动作时，对自身动作的感知与对他人动作的感知是否存在差异？先前使用识别和预测判断的研究表明，即使刺激信息简化为单个移动的点光源，情况依然如此。在此，我们评估了这种差异是否也会影响动作的时间安排。这在两个实验中通过一项特定的同步任务进行了测试。经过一些练习后，在无法基于易于察觉的线索充分完成预期的情况下，自我产生的动作事件比其他动作事件能被更快地预期到。我们结合先前关于动作感知中离线作者身份效应的研究结果对这些结果进行了讨论。
