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. This model paves the way for targeted interventions (CDPP-Adapt) and proposes a conceptual bridge between neuroscience and the philosophy of identity. Keywords : Identity development; emerging adulthood; prefrontal cortex; personal philosophy; socialization; cognitive flexibility; CDPP; functional connectivity.
