Synchrony perception for audio-visual stimulus pairs is typically studied by using temporal order judgment (TOJ) or synchrony judgment (SJ) tasks. Research has shown that estimates of the point of subjective simultaneity (PSS) obtained using these two methods do not necessarily correspond. Here, we investigate the hypothesis that the PSS estimate obtained in a TOJ task is shifted in the direction of the most sensitive part of the synchrony judgment curve, as obtained in an SJ task. The results confirm that criterion shifts in the TOJ task move the PSS toward regions of the audio-visual temporal interval continuum where discriminations are most sensitive.
对于视听刺激对的同步感知通常通过使用时间顺序判断（TOJ）或同步判断（SJ）任务来进行研究。研究表明，使用这两种方法获得的主观同时性点（PSS）估计值不一定相符。在此，我们研究这样一个假设：在TOJ任务中获得的PSS估计值会朝着在SJ任务中获得的同步判断曲线最敏感部分的方向偏移。结果证实，TOJ任务中的标准偏移会使PSS朝着视听时间间隔连续体中辨别最敏感的区域移动。
