群体生活在动物中很普遍，群体生活的一个主要优点是群体有能力解决超出个体能力的认知问题。人类也利用集体认知，同时发展出高度复杂的语言来交换信息。在此，我们研究了人类群体在现实情境中对语言使用的集体认知。每个人听了一段公告，必须单独或小组重建句子。人类经常遇到这种情况，例如在火车站或机场。利用机器语音识别的最新发展，我们从句法（即错误的数量）和语义（即检索信息的质量）的角度分析了个人和群体如何很好地重构句子。我们表明，群体在句法和语义层面上的表现甚至比他们最好的成员都要好。小组出错更少，在重建句子时能够检索到更多的信息，甚至超过了他们最好的小组成员。我们的研究将集体认知研究带入了人类语言使用的更复杂的层面。
Group-living is widespread among animals and one of the major advantages of group-living is the ability of groups to solve cognitive problems that exceed individual ability. Humans also make use of collective cognition and have simultaneously developed a highly complex language to exchange information. Here we investigated collective cognition of human groups regarding language use in a realistic situation. Individuals listened to a public announcement and had to reconstruct the sentence alone or in groups. This situation is often encountered by humans, for instance at train stations or airports. Using recent developments in machine speech recognition, we analysed how well individuals and groups reconstructed the sentences from a syntactic (i.e., the number of errors) and semantic (i.e., the quality of the retrieved information) perspective. We show that groups perform better both on a syntactic and semantic level than even their best members. Groups made fewer errors and were able to retrieve more information when reconstructing the sentences, outcompeting even their best group members. Our study takes collective cognition studies to the more complex level of language use in humans.
