It is often assumed that online collaboration, teamwork and communications is inferior to face-to-face equivalents as we miss the visual cues, facial, body language and so on. His would suggest that collaborative teamwork or meetings may be better with VIDEO ON, as opposed to JUST AUDIO.
Yet, this fascinating paper from Tomprou et al. (2021) at Carnegie Mellon, who looked at group ability to solve a range of different problems, found something quite counterintuitive. Visual cues have no effect on collaborative work. In fact, teams without visual presence were more successful, not only in synchronising their vocal cues but also speaking in turns and on solving problems. The authors rightly claim that this calls into doubt the conventional wisdom that you need video support.
