摘要

当我们听人讲话时，我们综合使用了不同感rn官耳朵是显然的；还有眼睛，用来看讲话者的rn脸部怎样改变我们所听到的辅音。此前，寻求rn将触觉也添加到其中的实验一直无法得出结论rn来。很多语言通过气流的用力排出(即送气音)rn来改变元音或辅音(比如说，在英语中来区分rn“da”和“pa”的发音——后者就是送气音)。rnBryan Gick和Donald Derrick将送气音作为起rn点，来研究触觉是否会有助于我们来“听”声rn音。他们向志愿者皮肤上喷出很小的、听不到rn的气流，与此同时志愿者又在听一系列辅音。rn以手部或脖子为目标喷出的气流使得“送气音”rn更有可能被听见。所以，在喷出一股气流之后，rn“b”被误听为“p”。这项工作在今后为听觉受rn损者研制助听器和辅助通信设备中可能会被证rn明是有用的。%Visual information from a speaker's face can enhance or interfere with accurate auditory perception. This integration of information across auditory and visual streams has been observed in functional imaging studies, and has typically been attributed to the frequency and robustness with which perceivers jointly encounter event-specific information from these two modalities. Adding the tactile modality has long been considered a crucial next step in understanding multisensory integration. However, previous studies have found an influence of tactile input on speech perception only under limited circumstances, either where perceivers were aware of the task or where they had received training to establish a cross-modal mapping. Here we show that perceivers integrate naturalistic tactile information during auditory speech perception without previous training. Drawing on the observation that some speech sounds produce tiny bursts of aspiration (such as English 'p'), we applied slight, inaudible air puffs on participants' skin at one of two locations: the right hand or the neck. Syllables heard simultaneously with cutaneous air puffs were more likely to be heard as aspirated (for example, causing participants to mishear 'b' as 'p'). These results demonstrate that perceivers integrate event-relevant tactile information in auditory perception in much the same way as they do visual information.
