Researchers have found similar patterns of brain activity in both boys and girls as they engage in basic math problems.

For the study, published in the journal Science of Learning, the research team from Carnegie Mellon University comprehensively examined the brain development of young boys and girls.

Through brain imaging, their research shows no gender difference in brain function or math ability.

“We see that children’s brains function similarly regardless of their gender. So hopefully we can recalibrate expectations of what children can achieve in mathematics,” said study researcher Jessica Cantlon from Carnegie Mellon University in the US.

For the findings, Cantlon and her team conducted the first neuroimaging study to evaluate biological gender differences in the math aptitude of young children.

Her team used functional MRI to measure the brain activity in 104 young children (3-to 10-years-old; 55 girls) while watching an educational video covering early math topics, like counting and addition.

The researchers compared scans from the boys and girls to evaluate brain similarity.

In addition, the team examined brain maturity by comparing the children’s scans to those taken from a group of adults (63 adults; 25 women), who watched the same math videos.

After numerous statistical comparisons, they found no difference in the brain development of girls and boys.

In addition, the researchers found no difference in how boys and girls processed math skills and were equally engaged while watching educational videos.

Finally, boys’ and girls’ brain maturity were statistically equivalent when compared to either men or women in the adult group.

The researchers also compared the results of the ‘Test of Early Mathematics Ability’, a standardised test for 3- to 8-year-old children, from 97 participants (50 girls) to gauge the rate of math development.

Air Pollution, Stress Associated with Thought Problems in Kids: Researchers

Stress likely leads to wide-ranging changes in, for example, epigenetic expression, cortisol, inflammation, and brain structure and function

Parents, please take note. Researchers have revealed that kids with elevated exposure to early life stress in the home and increased prenatal exposure to air pollution exhibited heightened symptoms of attention and thought problems.

Early life stress is common in youth from disadvantaged backgrounds who also often live in areas with greater exposure to air pollution, according to the study, published in the Journal of Child Psychology and Psychiatry.

“Prenatal exposure to polycyclic aromatic hydrocarbons, a neurotoxicant common in air pollution, seems to magnify or sustain the effects of early life social and economic stress on mental health in children,” said study first author David Pagliaccio from Columbia University in the US.

“Air pollutants are common in our environment, particularly in cities, and given socioeconomic inequities and environmental injustice, children growing up in disadvantaged circumstances are more likely to experience both life stress and exposure to neurotoxic chemicals,” said senior author Amy Margolis.

Air pollution has negative effects on physical health, and recent work has begun to also show the effects on mental health. Life stress, particularly in early life, is one of the best-known contributors to mental health problems.

This new study examined the combined effects of air pollution and early life stress on school-age children.

According to the researchers data were collected from the CCCEH Mothers and Newborns longitudinal birth cohort study in Northern Manhattan and the Bronx, which includes many participants who self-identify as African American or Dominican.

Mothers wore an air monitoring backpack during the third trimester of pregnancy to measure exposure to air pollutants in their daily lives.

When their children were 5 years old, mothers reported on stress in their lives, including neighbourhood quality, material hardship, intimate partner violence, perceived stress, lack of social support, and general distress levels.

Mothers then reported on their child’s psychiatric symptoms at ages 5, 7, 9 and 11.

The combined effect of air pollution and early life stress was seen across several measures of thought and attention problems/ADHD at the age 11.

The effects were also linked to PAH-DNA adducts–a dose-sensitive marker of air pollution exposure.

The researchers said that PAH and early life stress may serve as a “double hit” on shared biological pathways connected to attention and thought problems.

Stress likely leads to wide-ranging changes in, for example, epigenetic expression, cortisol, inflammation, and brain structure and function.

The mechanism underlying the effects of PAH is still being interrogated; however, alterations in brain structure and function represent possible shared mechanistic pathways, the study said. (IANS)
