Victor Borge once wrote, "Laughter is the closest distance between two people." Yet laughter isn't always positive for relationships. Think of your friend laughing at your embarrassing mistake. This kind of unshared laughter can have the opposite effect.
Now, a new study explores when laughter works as a social glue. While all genuine laughter may help us feel good, shared laughter may communicate to others that we have a similar worldview, which strengthens our relationships.
Researchers at the University of North Carolina found a way to produce shared laughter to measure experimentally how it might impact a relationship with a stranger. Participants watched a funny, not-so-funny, or not-funny-at-all video while video-chatting with another same-sex participant. Unknown to them, the video chat displayed a pre-recorded clip (片段) of someone laughing the same amount for each of the two funny videos, but only smiling occasionally during the unfunny video. This produced more shared laughter in the first situation, less shared laughter in the second, and no shared laughter in the third. Afterwards, the participants then filled out questionnaires about their sense of similarity to their video partner, and how much they liked or wanted to get to know their video partner.
Results showed that, across the different videos, the amount of shared laughter had consistent (一致的) effects on the participants' sense of similarity to the video partner ― and that this, in turn, increased how much participants liked their partner and wanted to affiliate with him or her. "For people who are laughing together, shared laughter signals that they see the world in the same way, and it momentarily improve their sense of connection," says Sara Algoe, co-author of the study.
How can we put these findings into practice? Algoe suggests that relationship partners may want to find opportunities to laugh together in order to boost closeness, especially before having difficult conversations. Likewise, shared laughter could be introduced into staff meetings to make people feel more on the same page and thus become more productive.
