在时间顺序知觉的研究中，多感觉整合的即时和持续效应已被反复证明。关于持续时间知觉，相应的文献报道明确了多感觉整合的即时效应，但关于多感觉持续整合的持续效应的证据很少。事实上，一项研究[Heron，J.et al.(2013年)。时间错觉的神经层次：持续时间适应先于多感觉整合，J.Vis。13、1-12。]研究了对多感觉冲突间隔的适应，发现视听冲突对随后呈现的单峰视觉间隔的感知持续时间没有持续的影响。在两个实验中，我们提供了独立的证据来支持这一发现。在实验1中，我们证明了对视听冲突的适应不会改变随后呈现的视觉测试间隔的感知持续时间。因此，复制了Heron等人的结果。(2013)，我们没有观察到多感觉持续时间整合的持续效应。然而，有人可能会争辩说，长期暴露在持续的多感觉冲突中可能阻止或阻碍了多感觉整合本身。在实验2中，我们通过证明视听冲突间隔的多感觉整合在视听冲突后仍然有效，从而排除了这一替代解释。这进一步证实了间隔时间的多感觉整合对知觉的影响是即时的，而不是持续的。
In studies on temporal order perception, immediate as well as sustained effects of multisensory integration have been demonstrated repeatedly. Regarding duration perception, the corresponding literature reports clear immediate effects of multisensory integration, but evidence on sustained effects of multisensory duration integration is scarce. In fact, a single study [Heron, J. et al. (2013). A neural hierarchy for illusions of time: Duration adaptation precedes multisensory integration, J. Vis. 13, 1-12.] investigated adaptation to multisensory conflicting intervals, and found no sustained effects of the audiovisual conflict on perceived duration of subsequently presented unimodal visual intervals. In two experiments, we provide independent evidence in support of this finding. In Experiment 1, we demonstrate that adaptation to audiovisual conflict does not alter perceived duration of subsequently presented visual test intervals. Thus, replicating the results of Heron et al. (2013), we observed no sustained effect of multisensory duration integration. However, one might argue that the prolonged exposure to consistent multisensory conflict might have prevented or hampered multisensory integration per se. In Experiment 2, we rule out this alternative explanation by showing that multisensory integration of audiovisual conflicting intervals is still effective after exposure to audiovisual conflict. This further strengthens the conclusion that multisensory integration of interval duration affects perception in an immediate, but not in a sustained manner.
