Iambic-Trochaic定律（ITL）声称，听者将更大的声音强度与组的开始和更长的持续时间与组的结束联系起来。一些研究者认为，这些感知倾向与语言节奏范畴的普遍原则之间存在自然联系。关于国际交易日志效应的实验文献在三个方面受到限制。很少有研究的听众的感知交替的声音序列使用语音刺激，跨语言测试一直不够，现有的研究操纵强度和持续时间单独，而这些功能在自然语音变化在一起。本文报道了三个实验的结果进行了母语为萨波特克人和一个母语为英语的人。我们使用强度和持续时间分别变化的交替音节流和它们共同变化的序列来测试听众的分组偏见。研究结果表明，应采取谨慎的假设之间的自然连接的国际交易日志和韵律组织的普遍原则。
The Iambic-Trochaic Law (ITL) asserts that listeners associate greater acoustic intensity with group beginnings and greater duration with group endings. Some researchers have assumed a natural connection between these perceptual tendencies and universal principles underlying linguistic categories of rhythm. The experimental literature on ITL effects is limited in three ways. Few studies of listeners' perceptions of alternating sound sequences have used speech-like stimuli, cross-linguistic testing has been inadequate and existing studies have manipulated intensity and duration singly, whereas these features vary together in natural speech. This paper reports the results of three experiments conducted with native Zapotec speakers and one with native English speakers. We tested listeners' grouping biases using streams of alternating syllables in which intensity and duration were varied separately, and sequences in which they were covaried. The findings suggest that care should be taken in assuming a natural connection between the ITL and universal principles of prosodic organisation.
