Note: N=258. Socioeconomic resources and amygdala reactivity measured at age 20. Amygdala reactivity represents a mean of activity across right and left amygdala regions of interest. All models include child race as a covariate. Models with antisocial behavior as the outcome also include antisocial behavior at age 20 as a covariate and models predicting income additionally include schooling status (i.e., in school or not) and housing status (i.e., living with family or independently) as covariates. Note that including income at age 20 as a covariate rather than as an indicator in the socioeconomic resource index, did not change that the results of our models predicting income at age 22.
