FIGURE 2.
Between-group results for which substance non-initiators (SN) participants demonstrate increased activation relative to Substance Initiators (SI) adolescents. Interaction charts depict mean parameter estimates (error bars represent standard errors) for (A) High-reward/risk > Low-reward/risk, left insula; and (B) Win > Lose, left anterior cingulate cortex (ACC). FSIQ as covariate of no interest. Initial cluster defining threshold = p < 0.001, k = 10 voxels. Results survive FWE cluster-correction at p < 0.05.
