“Our brains are prediction generators, and when there are delays or the facial expressions are frozen or out of sync, as happens on Zoom and Skype, we perceive it as a prediction error that needs to be fixed,” said Paula Niedenthal, a professor of psychology at the University of Wisconsin at Madison who specializes in affective response. “Whether subconscious or conscious, we’re having to do more work because aspects of our predictions are not being confirmed and that can get exhausting.”
