Audiovisual integration relies on temporal synchrony between visual and auditory stimuli. The brain rapidly adapts to audiovisual asynchronous events by shifting the timing of subjective synchrony in the direction of the leading modality of the most recent event, a process called rapid temporal recalibration. This phenomenon is the flexible function of audiovisual synchrony perception. Previous studies found that neural processing speed based on spatial frequency (SF) affects the timing of subjective synchrony. This study examined the effects of SF on the rapid temporal recalibration process by discriminating whether the presentation of the visual and auditory stimuli was simultaneous. I compared the magnitudes of the recalibration effect between low and high SF visual stimuli using two techniques. First, I randomly presented each SF accompanied by a tone during one session, then in a second experiment, only a single SF was paired with the tone throughout the one session. The results indicated that rapid recalibration occurred regardless of difference in presented SF between preceding and test trials. The recalibration magnitude did not significantly differ between the SF conditions. These findings confirm that intersensory temporal process is important to produce rapid recalibration and suggest that rapid recalibration can be induced by the simultaneity judgment criterion changes attributed to the low-level temporal information of audiovisual events.

视听整合依赖于视觉和听觉刺激之间的时间同步。大脑通过将主观同步的时间沿最近事件的主导方式的方向移动，从而迅速适应视听异步事件，该过程称为快速时间重新校准。这种现象是视听同步感知的灵活功能。先前的研究发现，基于空间频率（SF）的神经处理速度会影响主观同步的时间。这项研究通过区分视觉和听觉刺激是否同时出现来检验SF对快速时间重新校准过程的影响。我使用两种技术比较了低和高SF视觉刺激之间的重新校准效果的大小。第一，我在一个会话中随机呈现每个SF并伴有音调，然后在第二个实验中，在整个会话中只有一个SF与该音调配对。结果表明，无论先前试验与测试试验之间的SF差异如何，都可以进行快速重新校准。SF条件之间的重新校准幅度没有显着差异。这些发现证实了感官间的时间过程对于产生快速重新校准很重要，并暗示可以通过归因于视听事件的低水平时间信息的同时判断标准改变来诱导快速重新校准。结果表明，无论先前试验与测试试验之间的SF差异如何，都可以进行快速重新校准。SF条件之间的重新校准幅度没有显着差异。这些发现证实了感官间的时间过程对于产生快速重新校准很重要，并暗示可以通过归因于视听事件的低水平时间信息的同时判断标准改变来诱导快速重新校准。结果表明，无论先前试验与测试试验之间的SF差异如何，都可以进行快速重新校准。SF条件之间的重新校准幅度没有显着差异。这些发现证实了感官间的时间过程对于产生快速重新校准很重要，并且表明可以通过归因于视听事件的低水平时间信息的同时判断标准改变来诱导快速重新校准。
