Walking through doorways causes forgetting: situation models and experienced space

Abstract

We investigated the ability of people to retrieve information about objects as they moved through rooms in a virtual space. People were probed withobject names that were either associated withthe person (i.e., carried) or dissociated from the person (i.e., just set down). Also, people either did or did not shift spatial regions (i.e., go to a new room). Information about objects was less accessible when the objects were dissociated from the person. Furthermore, information about an object was also less available when there was a spatial shift. However, the spatial shift had a larger effect on memory for the currently associated object. These data are interpreted as being more supportive of a situation model explanation, following on work using narratives and film. Simpler memory-based accounts that do not take into account the context in which a person is embedded cannot adequately account for the results.
