What's the Connection Between Conversation and Psychic Connection?

In western cultures, on average, we spout out one syllable every hundred mill seconds. When two people are in a conversation, their brains synchronize with each other and they're both synchronizing off of the same stimuli. Is this causing a sort of desynchronization distraction that is degrading our efficiency in having a conversation? And is that contributing to the fact that we get fatigued more quickly when we're in a video conference than we're in inperson conversation?
