Two-category place representations persist over body rotations

Area of Science:

• Cognitive Psychology
• Spatial Cognition
• Environmental Psychology

Background:

• Understanding how humans form environment-centered frames of reference is crucial for spatial memory.
• Previous research often focused on 2D domains, leaving gaps in understanding enclosed spaces.

Purpose of the Study:

• To investigate how environmental geometry and external cues (environmental and object-based) influence spatial memory in an enclosed space.
• To determine if environmental geometry affects reference frame construction and object location memory.
• To test the applicability of the category-adjustment model to observed spatial memory phenomena.

Main Methods:

• Participants were assigned to groups receiving environmental cues (doors), object cues, or no external cues.
• The category-adjustment model (cue-based fuzzy boundary version) was used to fit the collected data.
• Object locations were remembered within a two-category (left vs. right) environmental frame.

Main Results:

• Environmental geometry significantly biased remembered object locations across all conditions.
• The influence of environmental geometry persisted even after participant body rotation, affecting front cues more than rear cues.
• Both door and object cues acted as boundaries for spatial categories during reorientation.

Conclusions:

• Environmental geometry plays a significant role in shaping spatial frames of reference and memory.
• Both environmental and object-based cues can effectively support environment-centered memory formation.
• The findings extend previous models by demonstrating the impact of environmental geometry in real-world spatial tasks.
