先前的研究表明，视觉间隔的感知持续时间受到冲突的听觉间隔的强烈影响。然而，目前尚不清楚这种间隔持续时间的多模式整合背后的机制是什么。为了研究这个问题，我们采用了具有空（实验1）或填充（实验2）间隔的再现任务，以及配对比较任务（实验3）来评估视觉标记间隔的感知持续时间，这可能伴随着具有一致（相同）或冲突（更长和更短）持续时间的听觉标记间隔。首先，我们预测冲突的听觉间隔会使视觉间隔的感知持续时间偏向听觉间隔的持续时间。其次，根据起搏器-累加器模型，两种不同的机制可能有助于多模式间隔积分：起搏器速率的变化或基于时间腹语效应的开关分量的变化。在前一种情况下，多模式偏差效应应随着间隔持续时间的增加而增加。在后一种情况下，效果应在整个间隔时间内保持恒定。所有实验都表明听觉间隔持续时间对感知视觉持续时间有很大影响。在实验 1 和 2 中，这种偏差效应随着间隔持续时间的增加而意外减少，这可能是由于所采用的持续时间再现方法的限制。然而，在实验 3 中，观察到的多模态偏差效应在所有间隔持续时间内都保持明显恒定。这一发现支持这样的观点：冲突时间间隔的多模态整合主要由时间腹语效应决定，该效应影响起搏器-累加器机制的开关组件。此外，我们证明双峰一致间隔被感知为比单峰视觉间隔更长。对于填充间隔（实验 2），但对于空间隔（实验 1）则不然，这种效应似乎是由起搏器频率增加引起的。
Previous studies demonstrated that perceived duration of visual intervals is strongly influenced by conflicting auditory intervals. However, it remains unclear which mechanisms underlie this multimodal integration of interval duration. To investigate this issue, we employed a reproduction task with empty (Experiment 1) or filled (Experiment 2) intervals, and a paired-comparison task (Experiment 3) to assess perceived duration of visually marked intervals, which could be accompanied by auditory marked intervals with congruent (same) or conflicting (longer and shorter) durations. First, we predicted that conflicting auditory intervals would bias the perceived duration of visual intervals towards the duration of the auditory ones. Second, according to pacemaker-accumulator models, two different mechanisms might contribute to multimodal interval integration: changes in pacemaker rate or changes of the switch component based on temporal ventriloquism effects. In the former case, the multimodal bias effect should increase with increasing interval duration. In the latter case, the effect should remain constant across interval durations. All experiments showed a strong influence of auditory interval duration on perceived visual duration. In Experiments 1 and 2, this bias effect unexpectedly decreased with increasing interval duration, which might be due to limitations of the employed duration reproduction method. In Experiment 3, however, the observed multimodal bias effect remained clearly constant across all interval durations. This finding supports the idea that multimodal integration of conflicting time intervals is mainly determined by a temporal ventriloquism effect, which affects the switch component of a pacemaker-accumulator mechanism. In addition, we demonstrated that bimodal congruent intervals are perceived as longer than unimodal visual ones. For filled (Experiment 2), but not for empty (Experiment 1) intervals, this effect seems to be caused by an increase in pacemaker rate.
