In their article, “Socioeconomic status and the brain: mechanistic insights from human and animal research,” Daniel A. Hackman, Martha J. Farah, and Michael J. Meaney explore how low socioeconomic status (SES) affects underlying cognitive and affective neural systems. They identify and focus on two sets of factors that determine the relationship between SES and cognitive development: (1) the environmental factors or ‘mechanisms’ that demonstrably mediate SES and brain development; and (2) those neurocognitive systems that are most strongly affected by low SES, including language processing and executive function. They argue that “these findings provide a unique opportunity for understanding how environmental factors can lead to individual differences in brain development, and for improving the programmes and policies that are designed to alleviate SES-related disparities in mental health and academic achievement” .
|Neuroscience can tell us how SES may affect her brain.
Can it move us to do something about it?
Theoretically, I have no doubt that neuroscience can make a powerful contribution to early childhood development by determining whether and which neurocognitive systems appear to be more extensively affected by low socioeconomic status.
