Summary
Gender differences in electroencephalographic activity (EEG) were observed during navigation tasks. While performance was similar, training altered brain activity synchronization differently between males and females, suggesting distinct working memory strategies.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Human-Computer Interaction
Background:
- Understanding gender-specific brain activity during spatial navigation is crucial for cognitive science.
- Previous research suggests potential differences in spatial processing between genders.
Purpose of the Study:
- To investigate gender differences in electroencephalographic (EEG) activity changes during a virtual navigation task after training.
- To explore how navigational training impacts brain activity synchronization in young adult females and males.
Main Methods:
- Assessed EEG changes in young adults (females and males matched for initial navigation performance) before and after a 9-session navigational skills training.
- Recorded EEG in an immersive virtual environment without visual cues during navigation task performance.
- Analyzed theta band coherence and correlation across different brain regions.
Main Results:
- Females exhibited higher frontal-parietal and frontal-central theta band coherence than males pre-training.
- Post-training, theta band correlation increased in the left hemisphere for females and the right hemisphere for males.
- Navigation training induced differential hemispheric synchronization changes in theta band activity between genders.
Conclusions:
- Navigation training promotes fronto-central-parietal synchronization in both genders, but with distinct hemispheric lateralization.
- Findings suggest that females may rely more on verbal-analytical working memory, while males utilize a global-spatial working memory mode during navigation.
