Ever noticed how friends end up walking in synch or how an audience will eventually clap together? Scientists have measured this mysterious “brain-brain synchrony.” Although this type of synchronous body movement has been observed widely, its neurological mechanism and its role in social interactions remain obscure. Researchers found that body-movement synchronization between two participants increases following a short session of cooperative training, suggesting that our ability to synchronize body movements is a measurable indicator of social interaction.
