Polyvagal Theory, developed by Stephen Porges, provides a neuroscience framework that explains many aspects of reaction formation in terms of the nervous system's safety-detection mechanisms.
The Three States of Polyvagal Theory and Reaction Formation
Ventral vagal (safe and social): Optimal state for connection, learning, and reaction formation management
Sympathetic mobilization (fight or flight): Anxiety-type reaction formation responses
Dorsal vagal shutdown (freeze/collapse): Depression and dissociation-type reaction formation
Neuroception and Reaction Formation
Neuroception — the body's unconscious safety-detection — can be dysregulated in reaction formation, causing false alarms (sensing danger when safe) that drive reaction formation responses.
Polyvagal-Informed Reaction Formation Treatment
Therapy that acknowledges the body's state — helping clients move into ventral vagal 'safe and social' — transforms reaction formation management.
Safe relationships, co-regulation, and body-based practices are particularly emphasized.
