The wide use of virtual communication has raised a need to understand its effect on communication effectiveness and the ways its different forms influence users’ information processing. To that end, this study proposes the Dynamical Interpersonal Communication Systems Model and posits that the amount of information directly perceived affects individual and dyadic information processing. This proposition is tested by examining how visual information influences physiological patterns, known to underlie information processing, during in-person, video, and audio-only conferences. Results indicate that while audio-only communication sustained emotional intensity better, visual-based communication required less initial cognitive effort. Visual information in combination with physical presence (in-person communication) resulted in consistently lower cognitive effort and stronger synchronization of positive emotions, compared to contexts involving visual but without embodied information (video communication). This study shows the importance of investigating interpersonal communication simultaneously across multiple systems and at the intra- and inter-personal levels.

面对面、视频会议还是音频会议？检查作为通信系统功能的个体和二元信息处理

虚拟通信的广泛使用提出了了解其对通信有效性的影响及其不同形式影响用户信息处理的方式的需求。为此，本研究提出了动态人际沟通系统模型，并假设直接感知的信息量会影响个人和二元信息处理。通过检查视觉信息如何影响生理模式来测试这一命题，这些生理模式是信息处理的基础，在面对面的视频和纯音频会议中。结果表明，虽然纯音频交流可以更好地维持情绪强度，但基于视觉的交流需要较少的初始认知努力。与涉及视觉但没有具体信息的环境（视频通信）相比，视觉信息与身体存在相结合（面对面的交流）导致认知努力持续较低，积极情绪的同步性更强。这项研究表明了跨多个系统以及在人际和人际层面同时调查人际沟通的重要性。
