Spatial updating of real objects occurs automatically when imagining environments. However, automatic updating of imagined environments requires real-world interaction and perceptual experience, not just verbal descriptions.

Area of Science:

  • Cognitive Psychology
  • Spatial Cognition
  • Human Navigation

Background:

  • Spatial updating is crucial for navigation in both real and imagined environments.
  • Previous research suggests spatial updating can occur automatically.
  • The conditions under which automatic spatial updating operates remain incompletely understood.

Purpose of the Study:

  • To compare spatial updating in real versus imagined environments.
  • To investigate the conditions necessary for automatic spatial updating.
  • To examine the role of perceptual experience in spatial updating.

Main Methods:

  • Three experiments were conducted comparing spatial updating in real and imagined settings.
  • Participants learned object locations in a room and imagined their kitchens.

  • Participants turned and pointed to targets in both environments before and after movement.

    • Main Results:

    • Real environment objects were automatically updated when participants turned in an imagined environment.
    • Imagined environment targets were not automatically updated when participants turned in the real environment.
    • Automatic updating of real objects required visual or tactile perception, not verbal descriptions.

    Conclusions:

    • Automatic spatial updating is asymmetric, depending on the environment's reality and perceptual engagement.
    • Perceptual experience is a key factor for automatic spatial updating of real-world objects.
    • Explicit spatial updating is equally efficient for both real and imagined environments.
