Interpersonal communication is an integral part of everyday life. People are constantly sharing thoughts, opinions, and information with others, both online and offline. Further, such social sharing has important implications for what people think, buy, and do. However, while it is clear that interpersonal communication is both frequent and important, research is only starting to understand what people share and why. This article reviews the literature on interpersonal communication and word of mouth, focusing on the drivers of social transmission and the implications for individuals and society at large. It discusses how factors like audiences, modalities (e.g., speaking or writing), channels (e.g., email or text), and devices (e.g., phone or PC) moderate what gets shared, and it outlines areas that deserve further attention. Such areas include the diffusion of false information, conversations and conversational dynamics, and how automated textual analysis can be used to shed light on a range of interesting questions.

共享哪些内容，为什么共享？人际沟通和口碑


人际交往是日常生活中不可或缺的一部分。人们不断地在线和离线与他人分享想法、意见和信息。此外，这种社交分享对人们的想法、购买和行为具有重要影响。然而，虽然很明显人际沟通既频繁又重要，但研究才刚刚开始了解人们分享什么以及为什么分享。本文回顾了有关人际沟通和口耳相传的文献，重点关注社会传播的驱动因素及其对个人和整个社会的影响。它讨论了受众、方式（例如口语或写作）、渠道（例如电子邮件或文本）和设备（例如电话或 PC）等因素如何调节共享内容，并概述了值得进一步关注的领域。这些领域包括虚假信息的传播、对话和对话动态，以及如何使用自动文本分析来阐明一系列有趣的问题。
