A, B, and C illustrate the relationships between Salience Network Connectivity, SCR Reactivity, and Subjective Arousal. Each dot represents one individual participant. More intense Subjective Arousal is predicted by both stronger Salience Network Connectivity (A) and higher SCR Reactivity (B), whereas Salience Network Connectivity and SCR Reactivity were not related to each other (C). Negative values for SCR reactivity indicate that the participant generated, on average, more SCRs for neutral than highly arousing images. *p < .05.
