Whose turn is it anyway? Latency and the organization of turn-taking in video-mediated interaction

Latency in video-mediated interaction can frustrate smooth turn-taking: it may cause participants to perceive silence at points where talk should occur, it may cause them to talk in overlap, and it impedes their ability to return to one-speaker-at-a-time. Whilst potentially frustrating for participants, this makes video-mediated interaction a perspicuous setting for the study of social interaction: it is an environment that nurtures the occurrence of turn-taking problems. For this paper, we conducted secondary analysis of 25 video consultations recorded for heart failure, (antenatal) diabetes, and cancer services in the UK. By comparing video recordings of the patient's and clinician's side of the call, we provide a detailed analysis of how latency interferes with the turn-taking system, how participants understand problems, and how they address them. We conclude that in our data latency unnoticed until it becomes problematic: participants act as if they share the same reality.
