The Philosophico-Prefrontal Co-Development Model (CDPP): A Neuro-Social Framework for Identity Resilience and Public Health Inclusion, from Emerging Adulthood to Lifelong Transitions

Identity development in emerging adulthood remains a fragmented field, oscillating between neuroscience and social sciences. The Philosophico-Prefrontal Co-Development (CDPP) model proposes an integrative theoretical framework linking personal philosophy, secondary socialization, and prefrontal functional connectivity. The CDPP describes a circular process: personal values (vmPFC) guide actions, generating social feedback that fuels behavioral and identity adjustment through executive mediation (dlPFC). Four identity profiles emerge, with the Flexible-Integrated profile illustrating optimal resilience rooted in high neural integration. Hypotheses are formulated to test the correlation between prefrontal connectivity, cognitive flexibility, and identity stability. Beyond individual development, this model provides a scalable architecture for public health inclusion, offering a conceptual bridge between neuroscience and national strategies for psychological resilience.This framework provides the theoretical basis for identity resilience and public health inclusion, extending from emerging adulthood to lifelong transitions."
