In the last century, treatment of social and learning disabilities has drastically changed. Through the Individuals with Disabilities Education Act, every student who qualifies for special education is entitled to a free and appropriate public education, delivered through an individualized education plan. An ‘IEP’ is designed through the collaboration of parents, teachers, and special education specialists. The largest category of learning disability is the specific learning disability, of which dyslexia is a typical example.
The amount of care put into special education has drastically changed the lives of many individuals, however, special education excludes those who have a learning disability due to economic situations. This reflects a longstanding social and educational belief that learning disabilities are innate, the result of genetic predisposition and not due to upbringing. The prevailing paradigm did not believe that upbringing could have a significant effect on the development on the brain.
To little surprise, neuroscience is showing otherwise.
We have always known that acute incidents can have a significant effect on brain development and function (such as in the effects of repeated physical trauma on function), but recent research is suggesting that external factors during development, including many associated with poverty, can have significant, long-term effects. These factors include higher levels of environmental toxins, lower nutritional levels, and increased levels of parental neglect. Recent research suggests that external factors, including poverty, can have significant internal effects on the brain, including brain development and function. Poverty affects the development of the brain in multiple ways, including through poverty-associated factors such as higher environmental toxins, lower nutritional levels, and higher levels of parental neglect. However, the research of Gary Evans and Michelle Schamberg of Cornell University indicates that solely the added stress of low socioeconomic status is responsible for these effects.
