Super interesting. Are there theories on the neural mechanisms of these synchrony-related changes in behavior? I wonder how these findings could be used to improve collaborative decision-making. Maybe we need our politicians learning dance routines together before debate.

I like this line: "We also rhythmically coordinate our movements, gestures, speech patterns, body language, breathing patterns, footsteps and even our brain waves, with each other, often without even knowing it."

I actually teach this (mirroring) in my social cognition groups for people with serious mental illness. It's amazing the ways people physically mirror each other without even trying!
