Study tracks children's brain development.

摘要

Some of" the data validated trends seen in other studies. For example, children from low-income families performed somewhat more poorly on IQ and achievement tests and displayed more behavioral problems than did children from middle-income and higher-income families. However, the researchers found that children from families of different incomes did not differ on many measures of basic cognitive functions, such as memory and verbal fluency, or on most measures of social adjustment. Also, healthy low-income children performed above published norms for their demographic.
