Active and passive spatial learning in human navigation: acquisition of survey knowledge

Area of Science:

• Cognitive Psychology
• Neuroscience
• Spatial Cognition

Background:

• Active environmental exploration is thought to improve spatial learning compared to passive observation.
• However, the specific sensory and cognitive components driving this advantage remain unclear, with mixed findings in prior research.

Purpose of the Study:

• To investigate the distinct contributions of visual, vestibular, podokinetic information, and decision-making to the acquisition of metric survey knowledge.
• To differentiate the effects of these components within active (walking, wheelchair) versus passive (video) learning conditions.

Main Methods:

• Participants learned object locations in a virtual maze under 6 conditions: walking/wheelchair/video crossed with decision-making/guided.
• Metric survey knowledge was tested by navigating a novel shortcut without the maze.
• Performance was measured by accuracy in reaching target locations.

Main Results:

• Passive video exposure yielded slightly above-chance performance.
• Vestibular information in the wheelchair condition did not enhance learning.
• Podokinetic information during walking significantly improved angular accuracy.
• Decision-making had no significant impact across any condition.

Conclusions:

• Visual and podokinetic information are crucial for developing metric survey knowledge.
• Vestibular information and cognitive decision-making do not appear to contribute significantly.
• Podokinetic information is identified as the primary driver of active learning for metric survey knowledge acquisition.
