Girls, boys have similar brains with equal math ability

Washington, Nov 9: There are no gender differences in math ability, according to a study that examined the brain development of young boys and girls.

The researchers, including those from Carnegie Mellon University in the US, conducted the first neuroimaging study to evaluate biological gender differences in math aptitude of young children.

The results of the study, published in the journal Science of Learning, revealed that there are no differences in the brain development of girls and boys, including how they processed math skills.

"This is an important reminder that humans are more similar to each other than we are different," said study co-author Alyssa Kersey from the University of Chicago in the US.

The study also noted that both boys and girls were equally engaged while watching educational videos.

"It's not just that boys and girls are using the math network in the same ways but that similarities were evident across the entire brain," Kersey said.

As part of the study, the researchers used functional MRI to measure the brain activity in 104 young children between the ages 3 to 10 (55 girls and 49 boys) while watching an educational video covering early math topics, like counting and addition.

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

The team also examined brain maturity in the children by comparing their scans to those taken from a group of adults -- 63 adults; 25 women -- who watched the same math videos.

The researchers also compared the results of the Test of Early Mathematics Ability -- a standardized test for children between 3 and 8 years of age -- from 97 participants (50 girls and 47 boys) to gauge the rate of math development.

Overall, the findings indicated that math ability was equivalent among the children, and did not show a difference in gender, or with age.

The researchers could also not find a gender difference between maths ability and brain maturity.

Jessica Cantlon, the lead researcher of the study from Carnegie Mellon University, said the society and culture likely are steering girls and young women away from science, technology, engineering, and mathematics (STEM) fields.

The researchers said families spend more time with young boys in play that involves spatial cognition, and many teachers also preferentially spend more time with boys during math class, predicting later math achievement.

Cantlon also suspected that children pick up on cues from their parent's expectations for math abilities.

"Typical socialization can exacerbate small differences between boys and girls that can snowball into how we treat them in science and math," Cantlon said.

"We need to be cognizant of these origins to ensure we aren't the ones causing the gender inequities," she said.

The current study looked at early childhood development using a limited set of math tasks, the researchers said.

Cantlon and her team plan to assess a broader array of math skills during childhood development such as spatial processing and memory and follow the children over many years.

Should you let your babies "cry it out" or rush to their side? Researchers have found that leaving an infant to 'cry it out' from birth up to 18 months does not adversely affect their behaviour development or attachment.

The study, published in the Journal of Child Psychology and Psychiatry, found that an infant's development and attachment to their parents is not affected by being left to "cry it out" and can actually decrease the amount of crying and duration.

"Only two previous studies nearly 50 or 20 years ago had investigated whether letting babies 'cry it out' affects babies' development. Our study documents contemporary parenting in the UK and the different approaches to crying used," said the study's researcher Ayten Bilgin from the University of Warwick in the UK.

For the study, the researchers followed 178 infants and their mums over 18 months and repeatedly assessed whether parents intervened immediately when a baby cried or let the baby let it cry out a few times or often.

They found that it made little difference to the baby’s development by 18 months.

The use of parent’s leaving their baby to ‘cry it out’ was assessed via maternal report at term, 3, 6 and 18 months and cry duration at term, 3 and 18 months.

Duration and frequency of fussing and crying was assessed at the same ages with the Crying Pattern Questionnaire.

According to the researchers, how sensitive the mother is in interaction with their baby was video-recorded and rated at 3 and 18 months of age.

Attachment was assessed at 18 months using a gold standard experimental procedure, the strange situation test, which assesses how securely an infant is attached to the major caregiver during separation and reunion episodes.

Behavioural development was assessed by direct observation in play with the mother and during assessment by a psychologist and a parent-report questionnaire at 18 months.

Researchers found that whether contemporary parents respond immediately or leave their infant to cry it out a few times to often makes no difference on the short - or longer term relationship with the mother or the infants behaviour.

This study shows that 2/3 of mum's parent intuitively and learn from their infant, meaning they intervene when they were just born immediately, but as they get older the mother waits a bit to see whether the baby can calm themselves, so babies learn self-regulation.

The World Health Organisation has warned that the COVID-19 pandemic is entering a "new and dangerous" phase. Thursday saw the most cases in a single day reported to the WHO.

Tedros Adhanom Ghebreyesus said the day had seen 150,000 new cases with half of those coming from the Americas and large numbers also from the Middle East and South Asia, the BBC reported.

He said the virus was still spreading fast and the pandemic accelerating.

He acknowledged people might be fed up with self-isolating and countries were eager to open their economies but he said that now was a time for extreme vigilance.

Maria van Kerkhove, technical lead of the WHO's COVID-19 response, told a press conference the pandemic is "accelerating in many parts of the world".

"While we have seen countries have some success in suppressing transmission and bringing transition down to a low level, every country must remain ready," she said.

Mike Ryan, the head of the WHO's Health Emergencies Programme, said that some countries had managed to flatten the peak of infections without bringing them down to a very low level.

"You can see a situation in some countries where they could get a second peak now, because the disease has not been brought under control," he said.

"The disease will then go away and reduce to a low level, and they could then get a second wave again in the autumn or later in the year."

With the sales of chicken and mutton going down due to the coronavirus scare, it is the humble 'Kathal' (jackfruit) is emerging as an acceptable alternative.

'Kathal' is now selling at ₹120 per kilogram -- an increase of more than 120 per cent over the normal ₹50 per kilogram.

The jackfruit, in fact, is now priced higher than chicken which is selling at ₹80 per kilogram due to poor demand.

"It is better having a 'Kathal' biryani instead of a mutton biryani. It tastes reasonably good. The only problem is that 'Kathal' has been sold out in the vegetable market and is difficult to find," said Purnima Srivastava whose family savours non-vegetarian food on a regular basis.

The corona scare has hit poultry business so hard and the Poultry Farm Association recently organized a Chicken Mela in Gorakhpur to dispel the misconception that birds are carriers of the deadly virus.

"In fact, we gave away plateful of chicken dishes for Rs 30 to encourage people to savour the delicacies. We cooked one thousand kilograms of chicken for the Mela and the entire stock was sold out," said Vineet Singh, head of the Poultry Farm Association.

However, the Mela did not do much to dispel the fears about chicken, mutton or fish consumption amid the virus outbreak.
