“Tears of Joy” May Help Us Maintain Emotional Balance

Many life experiences, such as witnessing the birth of a child or finally achieving a long sought-after goal, can lead to what may seem like confusing expressions of emotion, like tears of joy. But new research suggests that these incongruous expressions may serve a fundamental purpose, helping us to maintain emotional balance.

The findings are forthcoming in Psychological Science, a journal of the Association for Psychological Science.

There are many examples of responding to a positive experience with a negative emotion. Take, for example, the emotional expressions people show in response to adorable babies – at the same time that adults coo at babies and swaddle them, they also can’t resist pinching, squeezing, and even playfully nipping or growling at them.

Surely people don’t intend actual harm to the babies with these aggressive behaviors  so why do they do it? Aragon and her colleagues at Yale designed several experiments to find out.

Data from an online survey of adults suggest that dimorphous expressions  two different expressions that have the same origin  aren’t situation-specific; rather, they seem to emerge in response to various kinds of positive emotions.

So, people who show dimorphous expressions in response to cute stimuli, like babies, tend to show them in response to other positive situations and emotions, such as crying during happy moments in movies. This suggests that dimorphous expressions may serve as a general mechanism of expression that helps to regulate positive emotion.

As part of the study, the researchers asked participants to look at and evaluate photos of different babies, some of whom appeared more infantile (i.e., rounder faces, bigger eyes) than others.

Participants showed higher expressions of care for the more infantile babies, saying that they wanted to take care of them and protect them. But they also reported higher expressions of aggression in response to these babies, saying that they wanted to pinch the babies’ cheeks and “eat them up.”

Another online study with 679 participants confirmed these findings, and revealed that participants were more likely to report feeling overwhelmed with very strong positive feelings in response to the more infantile babies.

Importantly, the data indicated that it was specifically this feeling of being overwhelmed by positive emotion that elicited the aggressive responses. People who showed higher expressions of aggression while looking at the babies tended to show a bigger drop-off in positive emotion five minutes after viewing the images, suggesting that the negative emotions helped them moderate their intense positive emotions, bringing them back to emotional equilibrium

These new discoveries begin to explain common things that many people do but don’t even understand themselves, Aragon said.

“These insights advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together,” she said.
