An American study has shown that the brains of kids belonging to low-income families process information differently to those of children from wealthier homes.
Can wealth affect the brain’s development? Apparently, yes! That’s what an American study has proved. According to the study’s results, children hailing from low-income families have lower brain development and hence, process information differently from their wealthier playmates.
Conducted at the University of California, Berkeley, the study involved 26 children in the age group of nine to ten years. Half of them were from low-income homes, while half from high-income families.
Health Insurance
Health insurance has emerged as one of the fastest growing segments in the non-life insurance industry with 30% growth in 2010-11 with annual premium collections being over Rs 6,000 crores.

During the test, the children were shown an image onto a screen. They had not been briefed about the picture.
The researchers measured the subjects' brain responses as they saw the picture.

"The low socio-economic kids were not detecting or processing the visual stimuli as well - they were not getting that extra boost from the prefrontal cortex," the BBC quoted Dr. Mark Kishiyama, one of the researchers, as saying.

Family's Food Insecurity Linked to the Smoking Adult
A new study has found that kids and adults living with adult smokers appear less likely to have daily access to enough healthy food compared with those living with non-smoking adults,

The researchers also referred to past studies that showed that children in low-income families were spoken to far less, on average hearing 30 million fewer words by the age of four.

Obesity Rises With the Rise in Family Income
A new study in Britain reveals that with the rise of family income, the risk of obesity also rises. It has been seen that the kids with rich middle class parents are more likely to be fat.

"We are certainly not blaming lower socioeconomic families for not talking to their kids - there are probably a zillion reasons why that happens," he said.
His colleague, Professor Robert Knight, added: "This is a wake-up call - it's not just that these kids are poor and more likely to have health problems, but they might actually not be getting full brain development from the stressful and relatively impoverished environment associated with low socio-economic status."
He believed that it was possible to achieve improvements, even in older children, through "proper intervention and training".
Dr Emese Nagy, from the University of Dundee, called it a "pioneering" study saying that it could help deeply understand how environment could affect brain development.
She said: "Children who grow up in a different environment may have very different early experiences, and may process information differently than children from a different environment."
She added: "The study showed that low socio-economic status children behaved exactly the same way as high socio-economic status children, but their brain processed the information differently."
