During the early postnatal years, most infants rapidly learn to understand two naturally evolved communication systems: language and emotion. While these two domains include different types of content knowledge, it is possible that similar learning processes subserve their acquisition. In this review, we compare the learnable statistical regularities in language and emotion input. We then consider how domain-general learning abilities may underly the acquisition of language and emotion, and how this process may be constrained in each domain. This comparative developmental approach can advance our understanding of how humans learn to communicate with others.

获得复杂的交流系统：语言和情感的统计学习

在出生后的早期，大多数婴儿迅速学会理解两种自然进化的交流系统：语言和情感。虽然这两个领域包括不同类型的内容知识，但相似的学习过程可能有助于它们的获取。在这篇综述中，我们比较了语言和情感输入中可学习的统计规律。然后，我们考虑一般领域的学习能力如何成为语言和情感习得的基础，以及这一过程如何在每个领域中受到限制。这种比较发展的方法可以促进我们对人类如何学习与他人交流的理解。
