Poverty shapes people in some hard-wired ways that we're only now beginning to understand. Back in August, we wrote about some provocative new research that found that poverty imposes a kind of tax on the brain. It sucks up so much mental bandwidth – capacity spent wrestling with financial trade-offs, scarce resources, the gap between bills and income – that the poor have fewer cognitive resources left over to succeed at parenting, education, or work. Experiencing poverty is like knocking 13 points off your IQ as you try to navigate everything else. That's like living, perpetually, on a missed night of sleep....
"Some new research about the long-term arc of poverty, particularly on the brain, was recently published in theProceedings of the National Academy of Sciences, and these findings offer a useful complement to the earlier study....
"Poor children, in effect, had more problems regulating their emotions as adults (regardless of what their income status was at 24). These same patterns of "dysregulation" in the brain have been observed in people with depression, anxiety disorders, aggression and post-traumatic stress disorders.
"Over the course of the longitudinal study – which included 49 rural, white children of varying incomes – these same poor children were also exposed to chronic sources of stress like violence and family turmoil, or crowded and low-quality housing. Those kinds of stressors, the researchers theorize, may help explain the link between income status in childhood and how well the brain functions later on. That theory, they write, is consistent with the idea that "early experiences of poverty become embedded within the organism, setting individuals on lifelong trajectories."

This appears to be important, ground-breaking, scientific confirmation of what many have been asserting for quite some time.
