Figure 6

Mediation path diagram for all three key mediators of social evaluative threat (SET) effects on heart rate. Solid black lines indicate significant relationships, and light gray lines indicate non-significant relationships. Connections hypothesized to be directional are shown as one-way arrows, whereas effects likely to be bi-directional (feedback loops) based on anatomy are shown as double-headed arrows. Causality could only be inferred for the SET-brain effects because SET was experimentally manipulated. First-level effects (SET-brain connectivity for Path a or brain-HR connectivity for Path b) are shown as line plots, and second-level effects (correlations between Path a or Path b and HR reactivity) are shown as scatterplots. Effect plots are shown for pregenual cingulate (pgACC) and medial orbitofrontal cortex (mOFC), but are omitted for putamen (Put) for space reasons. Full statistics are presented in Table 5.
