Researchers at McMaster's LIVELab have identified a correlation between romantic interest and the synchronization of body sway during speed dating. The study suggests that unconscious physical movements can serve as indicators of interpersonal connection.
Why it matters
This research provides insights into human social behavior and the non-verbal cues that influence romantic attraction.
Along with all the other nightmares that come with dating, the question of whether the person you are doing it with actually likes you is certainly up there in terms of sources of stress. In one study which set people speed dating and monitored the results, researchers found an unusual sign to look out for; how they are swaying their bodies. You don't need IFLScience to tell you that throughout life, we give away a lot of unconscious signals through our body language. Smiling all the way to the eyes, for example, can show familiarity, whilst clutching your stomach and rubbing it might indicate you are in severe need of a poop, if my own children are anything to go by. As well as this, how well your own body movements sync up with the people around you can tell onlookers a few things about your relationship.
