Developing global spatial representations through across-boundary navigation.

Area of Science:

• Cognitive Psychology
• Spatial Cognition
• Human Navigation

Background:

• Understanding how humans form mental representations of environments is crucial for cognitive science.
• Across-boundary navigation, moving between distinct spaces, poses challenges for developing a cohesive global representation.

Purpose of the Study:

• To investigate the conditions under which people develop global spatial representations through navigation between local environments.
• To examine the role of prior global knowledge and navigation method (locomotion vs. teleportation) in spatial representation.

Main Methods:

• Participants learned object locations in two misaligned virtual reality rooms.
• A priming task assessed responses to locally or globally consistent views across rooms.
• An across-boundary pointing task measured participants' estimated global headings after navigation.

Main Results:

• Global priming effects and accurate global heading estimations occurred when participants learned landmarks and locomoted between rooms via a simple path.
• Local priming effects dominated when participants lacked prior landmark knowledge or were teleported between rooms.
• Prior global representations and path-based navigation facilitate the development of global spatial understanding.

Conclusions:

• People can develop global representations of local environments through across-boundary navigation.
• This ability is contingent upon having prior global representations and engaging in path-based locomotion between spaces.
