Global frames of reference organize configural knowledge of paths.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Spatial Cognition

Background:

• Understanding how humans form spatial memories is crucial for navigation.
• Previous research suggests reliance on egocentric or allocentric frames of reference.
• The role of contextual cues in establishing a global frame of reference for complex paths remains unclear.

Purpose of the Study:

• To investigate whether individuals establish a single global frame of reference or multiple path-aligned frames for an irregular path.
• To examine the influence of salient contextual cues on spatial memory organization.

Main Methods:

• Participants navigated a virtual six-segment path using a head-mounted display.
• Path segments were grouped into two sets with internal alignment and inter-set misalignment (45°).
• Judgments of Relative Directions (JRD) were used to assess spatial memory accuracy after repeated exposure.

Main Results:

• Pointing errors were lower for the most salient leg (longest or first) when contextual cues were consistent.
• When contextual cues were inconsistent, pointing errors were similar for different path segments.
• The salience of the longest leg and the presence/alignment of a room influenced the established frame of reference.

Conclusions:

• A single global frame of reference is established when a dominant contextual cue is present.
• Inconsistent or competing contextual cues can lead to the formation of multiple, oblique reference frames.
• Spatial memory organization is flexible and adapts based on environmental salience and consistency.
