Emotional contagion describes when one person’s emotions and related behaviors trigger similar emotions in another person. Our emotions can trigger other people’s emotions and vice versa because People mimic the facial expressions and body language of other people during social interactions and “catch” their emotions. You have probably experienced the impact of emotional contagion in your family. Someone (mom, dad, teen) comes home in a bad mood and suddenly everyone’s mood takes a turn for the worse. On the other hand, the same person comes home with a smile on their face and a bounce in their step and everyone feels better.
A smile on their face…that reminds me. Ka-shing Woo and Bobbie Chan conducted a study (2019) focusing on the impact of different types of smiles and nodding on warmth and friendliness between people. They found that a fake smile did NOT pass along good feelings. However, a genuine smile did pass along good feelings. They also found that slow, vertical head nodding communicates supportiveness and indicates the listener is paying attention. When the study participants combined a genuine smile with a slow, vertical head nod, they found a “potent emotional contagion” expressing warmth and friendliness that also served as a catalyst for reciprocal feelings of warmth and friendliness. In other words, genuine smiling and attentive nodding spreads warmth and friendliness, it draws people together in positive emotions, it builds intimacy…it is an emotional contagion of warmth and friendliness.
Interesting, isn’t it? A genuine smile combined with a nod of interest conveys a warmth and friendliness that is “catchy.” Now that is a contagion I would like to spread through my family. That is a contagion I would like to see spread through my family to the community as well. So, let’s start spreading that contagion today. Pass along a genuine smile and a nod of interest every chance you get.
