Response inhibition refers to performance on the Go/No-Go task, determined as an efficiency score (No-Go accuracy / Go reaction time). Family income is parent report of monthly gross household income, including sources such as government assistance or child support. Maternal education is parental report of years of education completed. Neighborhood poverty is census tract data indicating the percent of families with children under 18 within the census tract who were living below the poverty line from 2011 – 2015. IFG activation was extracted from a bilateral PickAtlas anatomical IFG mask.
