Does hemispheric asymmetry decrease with age?

basically,want a hypothesis that states a negative or positive correlation between hemispheric asymmetric and ageing based on the literature.The literature should be a mix of positive or negative correlation and then came out with a hypothesis . At the end of the discussion part, you just need to confirm or reject the hypothesis and related to the previous literature. Include study limitations and future improvements. You What is hemispheric asymmetry and how it is observed in the visual system

Describe how the task used in the present study allows the investigation of hemispheric asymmetry

What new knowledge does this study bring and why is it worth presenting?

How is it different from what previous experiments used to investigate hemispheric asymmetry and age?
