2 min readKey summary
Two Israeli researchers found that 24 girls walking in pairs often matched their steps spontaneously, especially when holding hands.
The article links this body synchronization to studies of cardio-respiratory and movement synchrony, and to empathy and cooperation.
The finding suggests physical coordination between people may strengthen mutual perception, group cohesion, and social bonding.
It may also reflect an evolutionary tool that helped humans live together in groups.
