Abstract

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, J., 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.

摘要

判断视听事件的持续时间是很常见的,然而,持续时间的判断如何受到来自其他模态信号的影响仍然存在争议。我们使用了一个oddball范式来研究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。在一系列标准刺激和oddball刺激中,参与者将oddball刺激的持续时间与标准刺激的持续时间进行比较。结果显示了不对称的跨模态效应,支持了听觉优势假说:声音会延长感知到的视觉持续时间,而视觉对象对感知到的听觉持续时间没有影响。我们使用不同的标准持续时间对标量期望理论[吉本,J.,丘奇,R. M.,& 梅克,W. H.(1984)。记忆中的标量计时。在J. 吉本和L. 艾伦(编),《纽约科学院学报》:第423卷。计时与时间感知(第52 - 77页)。纽约:纽约科学院]中提出的可能机制(起搏器或模式切换)进行了检验。我们得出结论,声音通过加快视觉起搏器中的脉冲速率来增加感知到的视觉持续时间。
