A bilingual advantage has been found in both cognitive and social tasks. In the current study, we examine whether there is a bilingual advantage in how children process information about who is talking (talker-voice information). Younger and older groups of monolingual and bilingual children completed the following talker-voice tasks with bilingual speakers: a discrimination task in English and German (an unfamiliar language), and a talker-voice learning task in which they learned to identify the voices of three unfamiliar speakers in English. Results revealed effects of age and bilingual status. Across the tasks, older children performed better than younger children and bilingual children performed better than monolingual children. Improved talker-voice processing by the bilingual children suggests that a bilingual advantage exists in a social aspect of speech perception, where the focus is not on processing the linguistic information in the signal, but instead on processing information about who is talking.
在认知和社交任务中都发现了双语优势。在当前的研究中,我们探究在儿童处理关于谁在说话的信息(说话者声音信息)的方式上是否存在双语优势。以双语者为对象,较年幼和较年长的单语及双语儿童组完成了以下说话者声音任务:一项用英语和德语(一种不熟悉的语言)进行的辨别任务,以及一项说话者声音学习任务,在该任务中他们学习识别三位不熟悉的英语说话者的声音。结果揭示了年龄和双语状态的影响。在各项任务中,年长儿童比年幼儿童表现更好,双语儿童比单语儿童表现更好。双语儿童在说话者声音处理方面的改善表明,在语音感知的社会层面存在双语优势,在这个层面上重点不是处理信号中的语言信息,而是处理关于谁在说话的信息。
