Kea show three signatures of domain-general statistical inference

新西兰啄羊鹦鹉展示了三个领域通用统计推断的特征

生词：

kea：啄羊鹦鹉（来自新西兰）

signature：鲜明的特征

Abstract

① One key aspect of domain-general thought is the ability to integrate information across different cognitive domains.

领域通用性想法的一个关键方面是整合不同认知领域的信息的能力。

integrate v. 整合、成为一体
e.g. After the outbreak of COVID-19, you need to integrate exercise into your normal life.
在新冠肺炎爆发后，你必须让锻炼成为你日常生活的一部分。
e.g. The idea with young children is to integrate learning with play.
对幼儿的理念是寓教于乐。

② Here, we tested whether kea (Nestor notabilis) can use relative quantities when predicting sampling outcomes, and then integrate both physical information about the presence of a barrier, and social information about the biased sampling of an experimenter, into their predictions.

在本文中，我们测试了新西兰啄羊鹦鹉在预测抽样结果时，是否能使用相对量，并且把关于障碍存在的物理信息和关于实验者有偏的样本的社会信息与它们的预测结果结合起来。

③ Our results show that kea exhibit three signatures of statistical inference, and therefore can integrate knowledge across different cognitive domains to flexibly adjust their predictions of sampling events.

我们的研究表明，啄羊鹦鹉展示了推断统计的三个显著的特征，所以，它们能把知识和不同认知领域结合在一起，去灵活的调整它们对抽样事件的预测。

④ This result provides evidence that true statistical inference is found outside of the great apes, and that aspects of domain-general thinking can convergently evolve in brains with a highly different structure from primates.

这一结果提供了证据，证明真正的统计推断是在类人猿之外发现的，而领域一般思维的各个方面可以在与灵长类结构高度不同的大脑中聚合进化。

convergently：聚合地、收敛地
primate：灵长类动物

⑤ This has important implications not only for our understanding of how intelligence evolves, but also for research focused on how to create artificial domain-general thought processes.

这不仅对我们理解智能是如何进化的有重要意义，而且对专注于如何创建人工领域一般思维过程的研究也有重要意义。
