The Power of a Negative Mood: How It Enhances Analytical Thinking

According to new research, individuals who are in a negative mood may be more efficient at detecting inconsistencies in the things they read.

According to research from the University of Arizona, when you’re in a bad mood, you might want to focus on tasks that require attention to detail, such as proofreading.

A new study, published in Frontiers in Communication, led by the University of Arizona suggests that individuals in a negative mood may be quicker at spotting inconsistencies in what they read. This study builds upon existing research on the way the brain processes language.

Vicky Lai, an assistant professor of psychology and cognitive science at the UArizona, collaborated with researchers in the Netherlands to investigate the differences in how people’s brains respond to language when they are in a positive versus a negative mood.

“Mood and language seem to be supported by different brain networks. But we have one brain, and the two are processed in the same brain, so there is a lot of interaction going on,” Lai said. “We show that when people are in a negative mood, they are more careful and analytical. They scrutinize what’s actually stated in a text, and they don’t just fall back on their default world knowledge.”

Lai and her study co-authors set out to manipulate study participants’ moods by showing them clips from a sad movie – “Sophie’s Choice” – or a funny television show – “Friends.” A computerized survey was used to evaluate participants’ moods before and after watching the clips. While the funny clips did not impact participants’ moods, the sad clips succeeded in putting participants in a more negative mood, the researchers found.

The participants then listened to a series of emotionally neutral audio recordings of four-sentence stories that each contained a “critical sentence” that either supported or violated default, or familiar, word knowledge. That sentence was displayed one word at a time on a computer screen, while participants’ brain waves were monitored by EEG, a test that measures brain waves.

For example, the researchers presented study participants with a story about driving at night that ended with the critical sentence “With the lights on, you can see more.” In a separate story about stargazing, the same critical sentence was altered to read “With the lights on, you can see less.” Although that statement is accurate in the context of stargazing, the idea that turning on the lights would cause a person to see less is a much less familiar concept that defies default knowledge.

The researchers also presented versions of the stories in which the critical sentences were swapped so that they did not fit the context of the story. For example, the story about driving at night would include the sentence “With the lights on, you can see less.”

They then looked at how the brain reacted to the inconsistencies, depending on mood.

They found that when participants were in a negative mood, based on their survey responses, they showed a type of brain activity closely associated with re-analysis.

“We show that mood matters, and perhaps when we do some tasks we should pay attention to our mood,” Lai said. “If we’re in a bad mood, maybe we should do things that are more detail-oriented, such as proofreading.”

Study participants completed the experiment twice – once in the negative mood condition and once in the happy mood condition. Each trial took place one week apart, with the same stories presented each time.

“These are the same stories, but in different moods, the brain sees them differently, with the sad mood being the more analytical mood,” Lai said.

The study was conducted in the Netherlands; participants were native Dutch speakers, and the study was conducted in Dutch. But Lai believes their findings translate across languages and cultures.

By design, the study participants were all women, because Lai and her colleagues wanted to align their study with existing literature that was limited to female participants. Lai said future studies should include more diverse gender representation.

In the meantime, Lai and her colleagues say mood may affect us in more ways than we previously realized.

Researcher Jos van Berkum of the Netherlands’ Utrecht University, co-authored the study with Lai and Peter Hagoort of the Max Planck Institute for Psycholinguistics in the Netherlands.

“When thinking about how mood affects them, many people just consider things like being grumpy, eating more ice cream, or – at best – interpreting somebody else’s talk in a biased way,” van Berkum said. “But there’s much more going on, also in unexpected corners of our minds. That’s really interesting. Imagine your laptop being more or less precise as a function of its battery level – that’s unthinkable. But in human information processing, and presumably also in (information processing) of related species, something like that seems to be going on.”

  1. Read through to the end.

    Really? They studied women, alone? So they’ve established results for women so far ….

    While their next hypothesis may seem well established, shouldn’t we wait for the results in a more diverse study group to state something as general as the title?
