The Entropic Process Personality Model (EPPM) applies General Coordination Dynamics (GCD) to individual psychological systems and their interpersonal couplings. Personality is modeled as a configuration of coordination subsystems—Emotional Relevance Modeling, Emotional Memory Loop, Conceptual Mapping Accuracy, Mirroring Feedback Stability, and Power Process Modulation—operating under finite coordination capacity, bounded energy gradients, and temporal asymmetry. The framework derives personality disorder configurations as characteristic viability regions within coordination state space, formalizes the exploration–stability tradeoff underlyingtherapeutic difficulty, introduces the actionability threshold distinguishing insight from change capacity, and predicts optimization trap dynamics leading to catastrophic failure modes. EPPM provides cross-scale consistency from individual through institutional dynamics using a single formal apparatus derived from domain-general coordination principles.
