The Impacts of the Microbiome, Genetics, Parenting & Culture on Children’s Behavior


Excerpt from the January 5th, 2021 Insider Mom Podcast:

Does culture determine whether or not our kids become introverts or extroverts? What makes some babies and kids more prone to fussiness while others are more calm? Also, can we positively influence our children’s behavior or is temperament primarily genetic?

Maria (Masha) Gartstein is a professor in the Washington State University Department of Psychology and the Clinical Psychology Doctoral Program Director. Masha and her collaborators’ research has focused on the role that parenting plays in how temperament “comes online” in early childhood. Their work is the subject of an episode in the Netflix documentary “Babies” filmed at the Gartstein Temperament Laboratory.

In this interview she answers some of the above questions and also discusses findings on the impacts of the microbiome, genetics, epigenetics, parenting and culture on children’s temperament.

She also talks about:

– Her childhood growing up

– The impacts of stress during pregnancy

– Difficulties and challenges women researchers and faculty face when they become mothers

– Individualism vs. collectivism and how what’s valued in each culture influences our childrens’ behavior

– The Frozen II motto she lives by

If you’re interested in learning about her fascinating research, make sure to tune into this episode.

How U.S. Babies Behave Differently From Infants in Other Cultures – HUFFPO

How U.S. Babies Behave Differently From Infants in Other Cultures – HUFFPO


Excerpt from Huffington Post Article January 2017:

Babies are comfortable expressing negative moods, while American babies are particularly active and social. That’s because the values and norms of your culture shape the person you’ll become from a young age, scientists believe.

And the earliest, and likely the most lasting, of these cultural influences comes from ― you guessed it ― your parents.

During the five years she spent studying babies around the world, Washington State University psychologist Dr. Maria Gartstein made some striking observations of how parents’ different cultural values influenced the temperaments and behavior of their babies. These temperamental patterns could set the stage for mental health or illness down the road.

Gartstein and her colleagues conducted a cross-cultural examination of the behavior of Chilean, Polish, South Korean and American babies, the results of which were recently published in the European Journal of Developmental Psychology. The mothers of 125 to 420 babies in each country were asked to fill out observations of more than 200 behaviors and temperamental qualities in their infants at 6 months and 1 year old, including activity level, shyness, sadness, cuddliness and attention focusing.

The results showed significant parenting differences across these four cultures. American babies, for instance, were more social and impulsive than babies from the other countries, and they were also the most likely to enjoy highly stimulating activities.

“[American babies] have some unique opportunities and challenges, compared to infants growing up in other regions of the world,” Gartstein said. “I really appreciate their readiness to engage and share enjoyment ― the baby version of extraversion, if you will.”

American mothers also reported that their babies were less likely to display negative emotions, and are easy to soothe when upset. This behavior may result from parents discouraging their children from expressing negative emotions.

The other babies, however, acted very differently. In fact, Garstein says that she was taken aback by the extent of the behavioral differences seen across cultures.

“One of my more profound moments occurred when I realized that parent-infant interaction dynamics varied dramatically, even in cultures we think of as being similar,” Gartstein told The Huffington Post.
