Situation models and abstract ownership relations

Six experiments used a fan-effect paradigm to test whether people can use the abstract relation of ownership to help integrate information into situation models. People studied sentences of the form The [person] owns/is buying the [object] for a later recognition test. The integration of sentences into a situation model (as evidenced by an attenuated or absent fan effect) was observed when the verb phrase referred to a specific event (is buying) and the objects could all be bought in the same place (e.g., a drugstore). This organization did not occur either when the verb phrase referred to general ownership (owns) or when the items were unlikely to be purchased in a single location (e.g., television and car). It was concluded that although abstract relations can be used to segregate information into sets that can be integrated into situation models, this integration is more likely when it can be embedded within a spatial-temporal framework.
