How poverty affects children’s brains, Washington Post: ... In a study published this year in Nature Neuroscience, several co-authors and I found that family income is significantly correlated with children’s brain size — specifically, the surface area of the cerebral cortex, which ... does most of the cognitive heavy lifting. Further, we found that increases in income were associated with the greatest increases in brain surface area among the poorest children. ...
Some feared the study would be used to reinforce the notion that people remain in poverty because they are less capable than those with higher incomes. As neuroscientists, we interpret the results very differently. We know that the brain is most malleable in the early years of life...
Our [new] clinical trial is designed to provide strong evidence regarding whether and how poverty reduction promotes cognitive and brain development. This study, however, will take at least five years to complete — far too long for young children living in poverty today. We should not wait until then to push for policies that can help inoculate young children’s pliable brains against the ravages of poverty. ...
