In a study recently published in the Journal of Cognitive Neuroscience, scientists said that normal 9- and 10-year-olds, differing only in socioeconomic status, have detectable differences in the response of their prefrontal cortex, the part of the brain that is critical for problem solving and creativity.
"This is a wake-up call," Knight said. "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 socioeconomic status: fewer books, less reading, fewer games, fewer visits to museums."
Kishiyama, Knight and Boyce suspect that the brain differences can be eliminated by proper training.
