The aim of this paper is to discuss the relationship of encyclopaedic knowledge and cultural models to intercultures that are co-constructed by interlocutors in intercultural communication.Intercultures as defined by are situationally emergent and co-constructed phenomena that rely both on relatively definable cultural models and norms as well as situationally evolving features.In the socio-cognitive approach that provides the theoretical framework for this paper,within the emerging intercultures encyclopaedic knowledge represents the relatively definable cultural models and norms that the interlocutors bring into the communicative situation based on their prior experience.This individual prior knowledge blends with the knowledge and information emerging from the actual situational context.This blend creates a third space that I call intercultures.According to this approach interculturality has both relatively normative and emergent components.This approach somewhat differs from other researchers' views that are dominated by a discoursive-constructivist perspective．
