Brain scans offer new dimension to the so-called “achievement gap”
Richer pupils achieve higher academic grades because their brains are different, according to research.
Past research has shown pupils from low-income backgrounds fared worse than those from wealthier families.
Brain scans have now offered another dimension to this so-called “achievement gap” by showing richer pupils have thicker brain cortex in areas associated with visual perception and knowledge accumulation. There was a link between the brain anatomy and performance on standardised tests.
John Gabrieli, a professor of brain and cognitive sciences at Massachusetts Institute of Technology, said: “Just as you would expect, there’s a real cost to not living in a supportive environment.
“We can see it not only in test scores, in educational attainment, but within the brains of these children.
“To me, it’s a call to action. You want to boost the opportunities for those for whom it doesn’t come easily in their environment.”
