判断视听事件的持续时间是很常见的，但来自其他方式的信号如何影响持续时间的判断仍然存在争议。我们使用一种奇怪的范式来检查声音对视觉持续时间判断的影响以及视觉对象对听觉持续时间判断的影响。在一系列标准和奇怪的事情中，参与者将奇怪的持续时间与标准的持续时间进行比较。结果显示不对称的跨模态效应，支持听觉优势假设：声音延长了感知的视觉持续时间，而视觉物体对感知的听觉持续时间没有影响。标量期望理论中提出的可能机制（起搏器或模式切换）[Gibbon, I., Church, R. M., & Meck, W. H. (1984)。内存中的标量计时。载于 J. Gibbon 和 L. Allan（主编），纽约科学院年鉴：卷。 423. 时机和时间感知（第 52-77 页）。纽约：纽约科学院]使用不同的标准持续时间进行了检查。我们得出的结论是，声音通过加速视觉起搏器的脉冲速率来增加感知的视觉持续时间。 (C) 2009 Elsevier B.V. 保留所有权利。
it is common to judge the duration of an audiovisual event, and yet it remains controversial how the judgment of duration is affected by signals from other modalities. We used an oddball paradigm to examine the effect of sound on the judgment of visual duration and that of a visual object on the judgment of an auditory duration. In a series of standards and oddballs, the participants compared the duration of the oddballs to that of the standards. Results showed asymmetric cross-modal effects, supporting the auditory dominance hypothesis: a sound extends the perceived visual duration, whereas a visual object has no effect on perceived auditory duration. The possible mechanisms (pacemaker or mode switch) proposed in the Scalar Expectancy Theory [Gibbon, I., Church, R. M., & Meck, W. H. (1984). Scalar timing in memory. In J. Gibbon & L. Allan (Eds.), Annals of the New York Academy of Sciences: Vol. 423. Timing and time perception (pp. 52-77). New York: New York Academy of Sciences] were examined using different standard durations. We conclude that sound increases the perceived visual duration by accelerating the pulse rate in the visual pacemaker. (C) 2009 Elsevier B.V. All rights reserved.
