Across all three task scenarios, there was a significant effect of task (p = 7.7 × 10–8), group (p = .024), and trend level interaction effect (p = .058) on phase-space trajectory lengths(A). Reappraise trajectory lengths negatively correlated with Reappraise scores on the ERQ in SAD participants (r=−0.64, p=0.002) (B). Maintain trajectory lengths positively correlated with negative affect ratings during the Maintain task scenario in the total sample (r=0.381, p=0.022) (C).
