Face-to-face conversation has been shown to be influenced by features that ensure comprehensible and linear conversation (“endogeneity”), and attributes of its potential participants, such as organizational position or contextual role, that “permeate” these endogenous effects. A direct comparison of both features is rarely studied, however, due to methodological challenges it presents. In addition, conversation is increasingly taking place in new mediated forms, such as emails and social media. It remains to be seen if social dynamics observed in face-to-face conversation transfer to these new media forms. Using an email network among individuals during a military exercise, we use relational event modeling to determine whether social norms of communication dominate conversation flow in this medium and to what extent individual attributes affect the flow of messages to and from those in the organization. Though email communication does not require immediate response, we find that immediate-response turn-taking dynamics occur anyway; though emails are only visible to sender and recipient(s), we observe a “Matthew effect” in the communication sequence (i.e., those who receive many emails receive even more in the future). Finally, these dynamics are only marginally affected by measured individual attributes (e.g., military rank, situational awareness), suggesting the primacy of “endogenous” conversation dynamics in this network. We thus find that many previously-observed social dynamics in face-to-face conversation carry over to the new form, despite practical differences between the two types. This study is only one of a handful that directly compares endogeneity and permeation in a communication network.

事实表明，面对面对话受确保可理解和线性对话（“内生性”）的功能以及“渗透”这些内在影响的潜在参与者的属性（例如组织位置或上下文角色）的影响。然而，由于存在方法上的挑战，很少研究这两种功能的直接比较。另外，对话越来越以新的媒介形式进行，例如电子邮件和社交媒体。面对面对话中观察到的社会动态是否会转移到这些新媒体形式，还有待观察。在军事演习中使用个人之间的电子邮件网络，我们使用关系事件建模确定社交沟通规范是否主导了这种媒介中的对话流，以及各个属性在多大程度上影响了往来于组织中的消息流。尽管电子邮件通信不需要即时响应，但我们发现即时响应转弯动态仍然会发生。尽管电子邮件仅对发件人和收件人可见，但我们在通信顺序中观察到“马修效应”（即，收到很多电子邮件的人将来会收到更多）。最后，这些动态仅受测得的个体属性（例如，军衔，态势感知）的影响很小，这表明该网络中“内生”对话动态的重要性。因此，我们发现，许多以前在面对面交谈中观察到的社会动态都延续到了新形式中，尽管这两种类型之间存在实际差异。这项研究只是直接比较通信网络中内生性和渗透性的极少数研究之一。
