Every hierarchy for working models includes both general working models (higher in the hierarchy) and relationship-specific working models (lower in the hierarchy). Studies have supported the existence of both general working models and relationship-specific working models. People can report a general attachment style when asked to do so, and the majority of their relationships are consistent with their general attachment style. A general attachment style indicates a general working model that applies to many relationships. Yet, people also report different styles of attachments to their friends, parents and lovers. Relationship-specific attachment styles indicate relationship-specific working models. Evidence that general working models and relationship-specific working models are organized into a hierarchy comes from a study by Overall, Fletcher and Friesen.
