Speaker and Listener Brains Sync Up During Conversation
When you listen to someone talking your brain starts working in sync with the speaker. Greg Stephens (2010) put participants in his research study in an fMRI machine and had them record or listen to recordings of other people talking. What he found is that as someone is listening to someone else talk, the brains patterns of the two people start to couple, or mirror each other. There is a slight delay, which corresponds to the time it takes for the communication to occur. Several different brain areas were synced. He compared this with having people listen to someone talk in a language they did not understand. In that case the brains do not sync up.
Syncing + anticipation = understanding – In Stephen’s study, the more the brains were synced up the more the listener understood the ideas and message from the speaker. And by watching what parts of the brain were lighting up, Stephens could see that the parts of the brain that have to do with prediction and anticipation were active. The more active they were, the more successful was the communication.
