In summary, the mental working models that underlie attachment styles appear to contain information about self and information about others organized into relational schemas. The relational schemas are themselves organized into a three-tier hierarchy. The highest level of the hierarchy contains relational schemas for a general working model that applies to all relationships. The middle level of the hierarchy contains relational schemas for working models that apply to different types of relationships (e.g., friends, parents, lovers). The lowest level of the hierarchy contains relational schemas for working models of specific relationships.
