What is the main focus of this study?
The study focuses on age-related changes in functional connectivity of cognitive control networks during task switching.
How is fMRI data collected in this study?
fMRI data is collected from children and adults while they perform the dimensional change card sort task.
What analysis technique is used in this research?
The research employs multi-variate analysis, specifically Independent Component Analysis (ICA), on fMRI data.
What are the implications of the findings?
The findings provide insights into how cognitive control networks differ with age, which can inform developmental psychology.
