Hypothesis
Which working memory subsystem is essential for maintaining object locations during active navigation?
Conclusion
Good navigators rely on spatial working memory, while poor navigators use both spatial and verbal working memory.
Supporting Evidence
- Good navigators were only significantly impaired by the spatial secondary task.
- Poor navigators were impaired by both spatial and verbal secondary tasks.
- The visual secondary task did not significantly affect navigation performance in either group.
Takeaway
When people try to remember where things are while moving around, those who are good at navigating mostly use their spatial memory, while those who are not as good use both spatial and verbal memory.
Methodology
Participants navigated a virtual environment to remember object locations while performing secondary tasks that loaded different working memory subsystems.
Limitations
The study used a desktop virtual environment, which may not fully replicate real-world navigation experiences.
Participant Demographics
12 male and 12 female healthy volunteers, mean age 23 years.
