A virtual reality platform for memory evaluation: Assessing effects of spatial strategies

Area of Science:

• Cognitive Science
• Neuroscience
• Human-Computer Interaction

Background:

• Traditional human spatial memory assessments lack ecological validity.
• Virtual reality (VR) offers a promising avenue for more realistic spatial memory tasks.
• A gap exists in cross-species comparable spatial cognition research tools.

Purpose of the Study:

• To present and evaluate novel software for creating computer-assisted virtual environment (CAVE) spatial memory experiments.
• To develop an immersive spatial memory task for humans that mimics real-world navigation.
• To enable direct comparison of spatial memory across species.

Main Methods:

• Developed a spatial memory task within a CAVE system, allowing participant navigation via joystick.
• The task design facilitates immersive spatial exploration without VR goggles.
• Implemented a user-reported strategy assessment alongside memory performance evaluation.

Main Results:

• Participants who utilized spatial cues in the virtual environment exhibited significant learning.
• A significant performance advantage was observed in the memory test for strategy users.
• The developed tool allows for human spatial memory evaluation in an ecological setting.

Conclusions:

• The novel software provides an ecologically valid method for assessing human spatial memory.
• The task's design facilitates cross-species comparisons in spatial cognition research.
• This tool can be adapted for various spatial cognition assessments.
