Abstract:

This article advances a conceptual dialogue between Attachment Theory and Polyvagal Theory, positioning co-regulation as their central point of convergence. While Attachment Theory explains how early relational experiences shape emotional regulation and internal working models, Polyvagal Theory provides a neurophysiological framework for understanding how states of safety and threat organize affective and relational functioning. Integrating these perspectives, the paper examines how the experience of feeling safe with another constitutes a foundational condition for emotional regulation and psychotherapeutic change.

Rather than proposing a unified model, the article offers an integrative conceptual framework that preserves the specificity of each theory while highlighting their shared clinical focus on embodied relational safety. The analysis demonstrates how attachment patterns and autonomic states interact through co-regulation within therapeutic encounters, fostering emotional tolerance, relational trust, and narrative integration. This perspective contributes a refined clinical lens for understanding affective dysregulation, relational trauma, and attachment-based difficulties in contemporary psychotherapy.
