    Regions of interest. Regions of interest for the left amygdala (left) and right vlPFC (right) are shown. For the left amygdala, an anatomical ROI was used based on the probabilistic Harvard–Oxford Structural Atlas. The right vlPFC ROI mask was created using a spherical ROI centered at 56, 22, 8, a peak of activation for emotion labeling versus gender labeling in a study of healthy controls (Lieberman et al., 2007).

    vlPFC Trajectories. Analysis of the right vlPFC revealed a significant interaction (F(4,29)=5.43, p=.027) between age-related trajectories of functional activation during emotion labeling versus gender labeling for CHR patients and controls, such that controls showed increasing vlPFC activation whereas CHR patients showed decreasing vlPFC activation across development.

    Amygdala Trajectories. Regression analysis demonstrated a significant interaction (F(4,28)=4.84, p=.037) between age-related trajectories of left amygdala activation during emotion labeling versus emotion matching for CHR patients and controls, such that controls exhibited decreasing amygdala activation whereas CHR patients showed increasing amygdala activation with increasing age.

    Amygdala–prefrontal functional connectivity. CHR patients demonstrated weaker inverse task-dependent functional connectivity between the amygdala and prefrontal regions consisting of left orbitofrontal cortex and left inferior frontal gyrus, compared with controls (Z=3.82, p=.027, corrected).
