采用McGurk效应范式研究了日语和英语在听觉-视觉言语感知方面的语际差异的发展起源。参与者被要求在不同的信噪比水平下识别视听（听觉和视觉成分一致或不一致）、纯音频和纯视频中的音节。在以日语和英语为母语的两组成年人的实验1中，视觉影响反应的百分比和反应时间的结果支持了先前关于日本参与者的视觉影响较弱的报道。在实验2中，每个语言组增加了三个年龄组（6岁、8岁和11岁）进行测试。结果显示，日语和英语的6岁儿童的视觉影响程度较低且相当，英语参与者的视觉影响程度随着年龄的增长而增加，特别是在6至8岁之间，但日语参与者的视觉影响程度保持不变。这可能与英语成年人和年龄较大的儿童处理视觉言语信息的速度相对快于听觉信息有关，而日语参与者的反应时间没有发现这种跨模式差异。
The McGurk effect paradigm was used to examine the developmental onset of inter-language differences between Japanese and English in auditory-visual speech perception. Participants were asked to identify syllables in audiovisual (with congruent or discrepant auditory and visual components), audio-only, and video-only presentations at various signal-to-noise levels. In Experiment 1 with two groups of adults, native speakers of Japanese and native speakers of English, the results on both percent visually influenced responses and reaction time supported previous reports of a weaker visual influence for Japanese participants. In Experiment 2, an additional three age groups (6, 8, and 11 years) in each language group were tested. The results showed that the degree of visual influence was low and equivalent for Japanese and English language 6-year-olds, and increased over age for English language participants, especially between 6 and 8 years, but remained the same for Japanese participants. This may be related to the fact that English language adults and older children processed visual speech information relatively faster than auditory information whereas no such inter-modal differences were found in the Japanese participants' reaction times.
