My paper argues that cognition is fundamentally and constitutively structured by an agent’s ongoing engagement within social roles and shared norms. It investigates how socio-cultural structures constitute the space of possible actions and inferences available to embodied agents. I propose that roles, and the expected and regular norms that individuate them, function as dynamically evolving constraints on shared state spaces, shaping trajectories of action and forming the basis of habitual, socially situated cognition. On this view, sociocultural structures are not merely external influences but organizing conditions that co-constitute what counts as intelligible action. Conceptually, the project defends the claim that the stabilizing patterns of sociocultural structures should be treated as constitutive elements of distributed cognitive systems. Norms and shared practices organize what actions make sense, shape the appearance of reasons, help determine what is experienced as appropriate, expected and possible for agents as they skillfully navigate the world. Drawing on enactivism, I develop an account in which social practices sediment into habits, stabilize as institutions, and recursively structure future cognition and action. This framework integrates distributed cognition, social ontology, and collective intentionality.
