Three experiments examined how readers inferred spatial information that was relevant to a story character’s movements through a previously memorized layout of a fictional building relative to various tasks. This study also examined how inference measures were related to spatial imagery and reading comprehension ability. Replicating the spatial separation effect reported by , probed objects were responded to faster when they were located in the same room of a building as the main character of a narrative than when the objects were located in different rooms. Experiment 2 ruled out a simple name-based priming explanation of the spatial separation effect, and Experiment 3 demonstrated a facilitation for objects from the character’s target room even when readers were provided with a spatially indeterminate list description of the building. The construction-integration model of text comprehension accounted for the spatial separation effect in terms of variations in the knowledge-integration process. It was concluded that the integration of an enriched knowledge network can facilitate the process of mapping text information onto a developing mental representation of a discourse situation, a process that gains further support from spatial imagery and reading comprehension ability.
