The mental representation of knowledge acquired from maps.

    Summary

    Cognitive maps prioritize route distance over straight-line (Euclidean) distance when representing knowledge. This finding suggests psychological distance is shaped by travel paths, not just spatial proximity.

    Area of Science:

    • Cognitive Psychology
    • Spatial Cognition
    • Human-Computer Interaction

    Background:

    • Understanding how humans mentally represent spatial information from maps is crucial for navigation and decision-making.
    • Previous research has debated whether cognitive maps are based on Euclidean (straight-line) or network (route) distances.

    Purpose of the Study:

    • To investigate the role of route distance versus Euclidean distance in the mental representation of map-acquired knowledge.
    • To determine the primary factor influencing psychological distance in cognitive maps.

    Main Methods:

    • Utilized recognition priming tasks to assess associations between learned map locations.
    • Employed distance estimation tasks to quantify perceived spatial relationships.
    • Conducted two experiments to ensure robustness and rule out learning artifacts.

    Main Results:

    • Recognition priming effects were stronger between cities closer in route distance, irrespective of Euclidean distance.
    • Distance estimations corroborated priming results, supporting the dominance of route-based relationships.
    • Findings remained consistent across experiments, indicating robustness.

    Conclusions:

    • Psychological distance in cognitive maps is predominantly determined by route distance, not Euclidean distance.
    • Mental representations of spatial knowledge from maps are structured around traversable paths.
