Network control dynamics and subjective reactivity in physiological responses to psychosocial stress
Abstract
We integrated self-report, electrodermal activity, and EEG connectivity focused on the frontoparietal network (FPN) to predict psychosocial stress tolerance. A random forest model explained 23.5% of the variance. Two composites showed opposing effects: a higher stress response index predicted longer tolerance, whereas a stronger FPN causal connectivity predicted shorter tolerance. SECPT produced sympathetic-dominant arousal and attenuated global FPN connectivity. Findings provide insights into the mechanisms underlying stress tolerance in psychosocial contexts.
