The Takeaway

Researchers found that while different cultures have distinct rhythms for nodding and verbal feedback (backchanneling) in person, the lag and constraints of video software force everyone into a synchronized, tech-driven middle ground. The software itself acts as a cultural homogenizer.

From the abstract

Backchanneling is a core interactional practice through which listeners display attention, engagement, and affiliation during a conversation. While backchannels are used among most language communities, prior research suggests systematic variation across language groups in frequency, type and timing of these actions. However, following the rapid expansion of video-mediated interaction, it has become evident that video-calling constricts provision of well-timed listener feedback. It is therefore
