Experimental: 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.
