Scientists from the University of California conducted an experiment to determine how different emotions affect the degree of trust and forming relationships. Positive emotions often Express a willingness to cooperate and build relationships. The scientists ' conclusion is simple: to get new friends, you need to smile more. This writes the Psych Central.
The volunteers were asked to look at 6 emotional videos. The video had to look either in the company of a stranger, or with a roommate. If the movie evoked positive emotions, approaching the stranger was faster and easier.
At the first contact with a stranger, many people use the "Duchenne smile". It is the involuntary contraction of the lower circular muscle of the eye and zygomatic muscles. That smile can only appear in the background of sincere emotions. A fake smile is quite simple to recognize, say experts.
