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.

|
|
Change from baseline in brain representation during arithmetic task performance
Periodo de tiempo: 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.
|
Baseline and post-intervention (after 6 weeks)
|
|
Change from baseline in brain connectivity during arithmetic task performance
Periodo de tiempo: Baseline and post-intervention (after 6 weeks)
|
Neural activity will be measured during the functional magnetic resonance imaging arithmetic task. Data will consist of generalized psychophysiological interaction beta values from individual subject contrast maps for Small vs. Large contrast. |
