Intervention on Mathematical Problem-Solving Skills

20 augusti 2026 uppdaterad av: Vinod Menon, Stanford University

Interventions in Math Learning Disabilities: Cognitive and Neural Correlates

The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing and remediating weaknesses in arithmetic skills in children, including those with mathematical learning disabilities.

Intervention / Behandling
Experimentell: 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.
Arithmetic strategy training includes activities that progressively develop the efficient use of arithmetic problem-solving strategies.
Aktiv komparator: Speeded practice training
Participants complete 6 weeks of activities, 1-hour hybrid sessions daily for 3 days per week (in total 18 sessions), that focus solely on enhancing arithmetic fluency. Before and after training, participants complete arithmetic problem-solving tasks during neuroimaging sessions.

Åtgärdsbeskrivning
Tidsram
Change from baseline in arithmetic task performance (reaction time)
Tidsram: Baseline and post-intervention (after 6 weeks)
Performance will be measured by children's reaction time (milliseconds) on arithmetic task
Baseline and post-intervention (after 6 weeks)
Change from baseline in arithmetic task performance (accuracy)
Tidsram: Baseline and post-intervention (after 6 weeks)
Performance will be measured by children's accuracy (% trials correct) on arithmetic task
Baseline and post-intervention (after 6 weeks)
Change from baseline in latent cognitive measures of arithmetic task performance (drift rate)
Tidsram: Baseline and post-intervention (after 6 weeks)
Latent cognitive processing will be measured by drift rate from children's arithmetic task performance
Baseline and post-intervention (after 6 weeks)
Change from baseline in latent cognitive measures of arithmetic performance (post-error adjustment)
Tidsram: Baseline and post-intervention (after 6 weeks)
Latent cognitive processing will be measured by post-error adjustment from children's arithmetic task performance
Baseline and post-intervention (after 6 weeks)
Change from baseline in brain activation during arithmetic task performance
Tidsram: Baseline and post-intervention (after 6 weeks)
Neural activity will be measured during a functional magnetic resonance imaging arithmetic task. Data will consist of beta values from individual-subject contrast maps for the Small vs. Large contrast in the whole-brain general linear modeling functional magnetic resonance imaging analysis.
Baseline and post-intervention (after 6 weeks)
Change from baseline in brain representation during arithmetic task performance
Tidsram: 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
Tidsram: Baseline and post-intervention (after 6 weeks)
