Eksperimentel: Arithmetic strategy training
Participants complete 6 weeks of activities, 1-hour hybrid sessions daily for 3 days per week (in total 18 sessions), that progressively develop the efficient use of arithmetic problem-solving strategies.
Before and after training, participants complete arithmetic problem-solving tasks during neuroimaging sessions.

|
Change from baseline in brain representation during arithmetic task performance
Tidsramme: Baseline and post-intervention (after 6 weeks)
|
Neural activity will be measured during the functional magnetic resonance imaging arithmetic task.
Data will consist of spatial correlations of voxel-wise brain activation between Trained vs. Rest and Untrained vs. Rest contrasts for individual subjects.
