从多个说话者中提取有意义的信息依赖于感知隔离。日常视听(AV)语音中固有的时间同步统计数据为感知隔离提供了有力的基础。本文研究了3-7岁儿童多个说话者同步知觉分离的发展过程。孩子们要么看到四张相同的脸,要么看到四张不同的脸,在时间上抖动地表达同一句话,要么听到同一句话的可听版本,要么与其中一个说话者同步,要么与所有说话者同步。眼动追踪显示,随着年龄的增长,对时间同步的说话面孔的选择性注意力增加,而对非同步面孔的注意力减少,对说话者嘴部的注意力主要驱动反应。这些研究结果表明,在流畅的AV语音固有的时间同步统计承担越来越大的作用,在知觉隔离的多感官杂波多个说话的脸在幼儿期。
Extraction of meaningful information from multiple talkers relies on perceptual segregation. The temporal synchrony statistics inherent in everyday audiovisual (AV) speech offer a powerful basis for perceptual segregation. We investigated the developmental emergence of synchrony-based perceptual segregation of multiple talkers in 3–7-year-old children. Children either saw four identical or four different faces articulating temporally jittered versions of the same utterance and heard the audible version of the same utterance either synchronized with one of the talkers or desynchronized with all of them. Eye tracking revealed that selective attention to the temporally synchronized talking face increased while attention to the desynchronized faces decreased with age and that attention to the talkers' mouth primarily drove responsiveness. These findings demonstrate that the temporal synchrony statistics inherent in fluent AV speech assume an increasingly greater role in perceptual segregation of the multisensory clutter created by multiple talking faces in early childhood.
