People prove adept at predicting emotional transitions

Posted June 30, 2017

For most people, reading the emotions of those around you is second nature: Your spouse is grumpy. Your co-worker is anxious. Your child is happy.

But new work from researchers at Princeton University and Harvard University shows that people are also quite skilled at predicting others’ future emotions, thanks to a powerful mental model of emotional transitions.

“It’s one thing for me to know that your face right now is telling me that you’re happy, but that doesn’t give me any information about what I should do to prepare for whatever state you’re going to be in next,” said Diana Tamir, an assistant professor of psychology at Princeton and one of the researchers. “We found that people have really reliable, intuitive models for how people transition from one emotional state to the next.”

The research is detailed in an article titled “Mental models accurately predict emotion transitions,” published last month in the Proceedings of the National Academy of Sciences by Tamir and Mark Thornton, who did the work as Ph.D. student at Harvard and is now a postdoctoral researcher at Princeton. Thornton is also a member of Princeton’s Class of 2011.

For a social species like humans, the ability to predict the future emotions of those around us pays off all the time, whether you’re trying to comfort a loved one, outmaneuver a rival or close a sale. “This ability to see into others’ affective future may be one way by which humans achieve their impressive social abilities,” the researchers wrote.

To determine how likely people are to transition from one emotional state to another, the researchers looked at data from three studies that asked participants to record their current emotional state repeatedly over an extended time period. From that, the researchers estimated the actual rate of transitions between emotional states. Someone who reports feeling gloomy, for example, is much more likely to report next that they are feeling sad than they are to report feeling pleased.

Then, the researchers asked separate study participants to rate the likelihood that one emotion might transition to another.

“Comparing participants’ ratings of transition likelihood to others’ experienced transitions, we found that raters have accurate mental models of emotion transitions,” the researchers wrote. “These models could allow perceivers to predict others’ emotions up to two transitions into the future with above-chance accuracy.”

So, for example, the data on people’s reported emotional transitions showed it to be fairly likely that a person feeling touchy would next feel distressed. Similarly, the study participants rated “distressed” as an emotion likely to follow “feeling touchy.”

The researchers found evidence that the mental model people use to predict emotional transitions is informed by four conceptual dimensions:

  • valence, whether an emotion is positive or negative;
  • social impact, whether an emotion is intense and social or mild and asocial;
  • rationality, whether an emotion is more about cognition or affect; and
  • human mind, whether an emotion is purely mental and human-specific, or bodily and shared with animals.

Transitions are more likely to happen between emotions that share the same valence, for example. So, an emotion whose valence is positive, such as “giddy,” is more likely to be followed by another emotion with positive valence, such as “excited,” than an emotion with negative valence, such as “upset.”

Lisa Feldman Barrett, a University Distinguished Professor in the Department of Psychology at Northeastern University who is familiar with the work but wasn’t involved in it, said the research’s “focus on temporal dynamics, in particular, is an important innovation in the study of emotion perception.”

Tamir said the researchers are working to understand why some people are better than others at predicting emotional transitions and how different abilities translate to different levels of success in the world.
