Summary
Hemispheric asymmetry in spatial attention remains stable in men but shows significant changes in women aged 50-69. These findings suggest sex-specific neuromorphological changes impact cognitive development across adulthood.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Human Development
Background:
- Hemispheric asymmetries in cognitive functions are known to change with age.
- The specific mechanisms, whether unilateral hemispheric aging or altered interhemispheric interactions, remain unclear.
Purpose of the Study:
- To investigate age-related changes in hemispheric asymmetry of spatial attention.
- To determine if these changes differ between sexes.
Main Methods:
- A line-bisection task was administered to 281 neurologically healthy, right-handed adults aged 20-79.
- Data were analyzed to assess leftward bias in midpoint estimation and hand-effect variations.
Main Results:
- A consistent leftward bias, indicating right hemispheric superiority in spatial attention, was observed.
- This pattern was stable in men but showed a reduced leftward bias and hand effect in women aged 50-69.
- These sex differences suggest differential aging patterns in spatial attention.
Conclusions:
- Developmental changes in spatial attention asymmetry are more pronounced in women.
- Neuromorphological changes during adulthood may differ significantly between sexes, impacting cognitive functions.
