One Action, Two Reference Frames: Compound Cognitive Maps of Object Location

Area of Science:

• Cognitive Science
• Spatial Cognition
• Neuroscience

Background:

• Animals use body-based and environment-based reference frames for spatial navigation.
• The interaction between these reference frames in humans is not fully understood.
• Neuroscience suggests integration, while psycholinguistics suggests sequential use.

Purpose of the Study:

• To investigate whether humans spontaneously use multiple reference frames concurrently in a single action.
• To examine the interaction between body-based and environment-based frames during spatial tasks.

Main Methods:

• Adult participants (N=110) performed a spatial object placement task in a 2D array.
• Analysis focused on the reference frames used for object positioning.

Main Results:

• Participants routinely used a hybrid approach, employing an environment-based frame for left-right positioning and a body-based frame for front-back positioning simultaneously.
• This hybrid response pattern was consistent across Indigenous Tsimane' and educated U.S. participants.

Conclusions:

• Humans habitually construct compound cognitive maps by integrating multiple reference frames.
• This integration is crucial for representing complex, multidimensional spatial relationships in natural environments.
• Spatial cognition across cultures demonstrates a flexible, hybrid frame-of-reference system.
