SES × Age interactions in left superior temporal gyrus and left inferior frontal gyrus. A priori ROIs defined in FreeSurfer were chosen that related to language processing. Among the 44 children whose parent education ranged from 11 to 17.5 years, SES × child age interactions were observed in (A) left inferior frontal gyrus (IFG; dark blue) and left superior temporal gyrus (STG; light blue). This is portrayed graphically in (B) left IFG (Beta = 2.769; p < .014), and (C) left STG (Beta = 2.516; p < .012), suggesting that SES differences in regional brain volume are not uniform at different ages. In all plots, regional volume is portrayed as the standardized residual, in standard deviations, after adjusting for total cortical volume. All analyses were performed using continuous variables for child age, parent education, and ROI volume, but are displayed with parental education represented in terciles, with 11–13.5 years of parental education in green; 13.5–15 years of parental education in orange; and 15–17.5 years of parental education in blue.
