“Those who wrote about an emotional experience showed more activity in part of the brain called the right ventrolateral prefrontal cortex, which in turn dampened down neural activity linked to strong emotional feelings.
Men seemed to benefit from writing about their feelings more than women, and writing by hand had a bigger effect than typing, Dr Lieberman said.
“Men tend to show greater benefits and that is a bit counterintuitive. But the reason might be that women more freely put their feelings into words, so this is less of a novel experience for them. For men it’s more of a novelty,” Lieberman said.
The study showed that writing about emotions in an abstract sense was more calming than describing them in vivid language, which could make people feel more upset by reactivating their original feelings.”
