q2 i? Structural MRI studies of children and youth identify regionally specific differences in cortical surface area as a function of family income and parental education, with the SES-surface area relationship strongest at the lowest SES levels. → Martha J. Farah 2017

q2 · i? · theoretical · r3

The Perspective reports, citing Noble and colleagues' structural MRI analysis of children and youth controlling for genetic ancestry and other covariates, that "the relationship between surface area and SES was shown to be strongest at the lowest SES levels". No effect size is printed.

"the relationship between surface area and SES was shown to be strongest at the lowest SES levels; SES had a positive relationship with surface area at all levels of income and education, but the difference between poverty and near-poverty mattered most."

Discussion¶

Learner Variables¶

• Socioeconomic Status — predictor: outcomes differ by group: a gap reflecting circumstances and treatment, not a cause
