"Russian culture seems to value all emotions -- including negative emotions -- and it is important to learn from these emotions. Because the stories we read and hear as children often inform which emotions we value, we wanted to see how those stories might differ across these two cultures," Dutton added.
To that end, the researchers conducted two studies. In the first study, the researchers recruited 322 parents who had children under the age of 10. The parents belonged to three groups: 72 parents were born in the US and lived there; 72 parents were born in Russia, but lived in the US; 178 parents were born in Russia and lived there.
In this study, the researchers asked parents to describe the extent to which the books they read to their children depicted 10 different emotions -- six positive ones and four negative ones.
"There were no differences across groups when it came to the frequency of positive emotions -- everybody likes a book with some positivity," said Anita Adams, a graduate student at the University of Kentucky who worked on the project as an undergraduate at NC State.
"However, Russian parents chose to read books with more negative emotions than US parents. Russian-American parents were somewhere in between those two groups," she added.
And, when the researchers looked at parents' beliefs about the value of sadness, they found that Russian parents valued the experience of sadness more than US parents.
"That value seemed to be part of why they were willing to engage more with their children about negative emotions in general," Halberstadt said.
The second study evaluated the 40 best-selling fiction books aimed at preschool-age children in the US and Russia. The researchers analysed the text and illustrations of all 80 books to assess the range and frequency of positive and negative emotions.
This study found that a wider range of emotions are represented in the children's books that are popular in Russia, as compared to children's books popular in the US specifically, the text of Russian books referenced anger and sadness more often than the US books; and illustrations in Russian books depicted happiness, anger and fear more frequently than the US books. The researchers found this even when they accounted for differences in the length of texts and the number of illustrations featuring facial expressions.
"Taken together, these studies highlight how Russian parents engage with their children about emotions differently than US parents," Halberstadt said.
"Simply put, the study suggests Russian parents are more likely to support opportunities to engage with their young children about challenging emotions, such as anger and sadness. Future studies may want to explore what this might mean in terms of providing children more tools with which to navigate difficult emotions," she added.
